The East Side of Oahu: Hanauma Bay, Koko Head, Kailua & Lanikai, Kualoa Ranch & MORE

This post may contain some affiliate links, which means I’ll make a little money on anything you choose to purchase. But of course, I only recommend my absolute favorites to you. Thank you for supporting the brands that make HulaLand possible.

The east side of Oahu (the windward side) is (in my opinion) by far the most beautiful part of the island. It’s famous for its jagged green mountains, sweeping coastal views, laid back towns, gorgeous beaches, and top notch attractions that feel a world away from Waikiki. 

You absolutely need to plan at least a day (preferably more) exploring this side of the island!

If you’re the type that likes a good drive with a few stops, you could do this in one epic day. 

If you’re the type that likes to spend time snorkeling, hiking, sightseeing, shopping and bumming around the beach, then you could break this up into several days. 

If you’re looking to do EVERYTHING, I would recommend a day south of Kailua (snorkeling Hanauma Bay, Koko Head, Halona Blowhole, Waimanalo Beach, etc.), a day in Kailua (Kailua & Lanikai beaches, Lanikai Pillbox hike, kayaking, etc.), and a day north of Kailua (Ho’omaluhia Botanical Garden, Kualoa Ranch, etc.). If you pick and choose your favorites, you can do a lot in two days. 

Things to Do on the East Side of Oahu

So I’m going to break down my favorite things to do on the east side of Oahu starting at the southern end and going north. 

*If you’re driving from Waikiki and planning to focus on the Kailua area (and to the north), plan to drive over on the H3. It has the most EPIC views of Oahu and it’s an attraction in itself. Even if you’re driving around the island from Hanauma Bay/Koko Head northward, you should still try to do this at some point. 

Snorkeling at Hanauma Bay

Oahu’s most popular snorkeling spot, Hanauma Bay is a nature preserve now and they’re making attempts to restore the reef after years of abuse. 

It’s largely protected from the ocean and the reef is home to a huge range of species. It’s also a perfectly idyllic beach to wile away the day.

Parking and entry is limited and fairly, er, complicated, so you’re going to have to plan ahead if you want to visit Hanauma Bay. 

Currently, here are the details: 

Hanauma Bay is CLOSED on Monday and Tuesday to give the reef a chance to rest. 

Daily hours are 6:45AM to 4PM (last entry at 1:30PM, they start to clear the beach at 3:15PM, and the gates at the parking lot are closed at 4PM). 

Closed Christmas Day (Dec 25th) and New Years Day (Jan 1st). 

The entrance fee is $25/person (12 and under, active military, and local residents with Hawaii state idea are FREE). 

Parking is $3/vehicle, cash only. 

Here’s where it gets complicated: RESERVATIONS ARE REQUIRED for entry, and they book quickly. They can be booked online here at 7AM HST two days in advance. They’re limited and are usually gone within 5 minutes (if not sooner) of the release time. Only 1400 people are allowed into Hanauma Bay each day (40 people every 10 minutes). Reservations are spaced in 10 minute increments throughout the day. 

There are a limited number of walk in tickets available each day if you show up in person when the park opens. If you’re not able to get reservations online in advance, this is your only option. But you’ll have to show up early. 

Locals (with valid Hawaii state ID) can enter for free without reservations between 6:45AM and 9AM daily. After 9AM, you’ll need reservations like everyone else. 

The parking lot has 300 spaces and fills up first come first serve, even if you have reservations. So early is the name of the game here. 

A few more details: 

Snorkeling equipment is available to rent for $20/set. You can also bring your own. 

The snack bar on the main level (near the parking lot) is now open (including a small gift shop with beach essentials), but you’re also welcome to bring small coolers. 

Lockers are available to rent down at the beach level. 

A shuttle down to the beach and back is included. It’s a pretty steep walk. 

Things you should bring with you (if you want them): towels, swimsuits, chairs and umbrellas, life vests, waterproof phone cases or cameras, reef safe sunscreen. 

AND BESIDES ALL OF THIS: You’ll also want to monitor the conditions at Hanauma Bay closely before your trip as it’s a pretty delicate ecosystem and the state is really focused on protecting it (and keeping visitors safe). 

While it’s always closed on Mondays and Tuesdays, it can also close spur of the moment due to jellyfish (which sometimes has to do with the tides and moon phases and other times just seems random), and earlier this year experienced a more prolonged closure due to high bacteria levels in the water. 

Needless to say, snorkeling here can be hit or miss due to conditions, and as you now know it’s not the easiest place to access, but it truly is special.

***Want to save major $$$ on your trip to Hawaii? I get asked ALL the time how I’m able to travel so often to Hawaii and stay at really nice resorts. Well, my favorite travel hack is cashing in points to score free airfare and free nights at some of Hawaii’s most high end resorts. Read my full guide on the exact system I use to max out credit card rewards here. Seriously, it’s going to save you soooo much money. 

Hiking Koko Head Crater

Sometimes overshadowed by Diamond Head, this crater is a popular hike, but I’ve been told it makes Diamond Head seem easy. I haven’t done it yet, but It’s 1000 steps (on old railroad ties) straight to the top. Simple and straightforward, but a real leg burner. 

Lanai Lookout

As you cruise around Koko Head, the road really opens up to incredible coastal views and the Lanai Lookout is a great place to stop. 

Halona Blowhole

Blowholes always draw a big crowd in Hawaii, and this is one of the most easily accessible ones you’ll find. You just have to fight off the crowds from the tour buses to get a look! There’s a turnout on the highway with plenty of parking spots.

The strength of the blowhole does change throughout the day according to the tides. Low tide means a weak blowhole and high tide means a much stronger one. Actually last time I was there it was low tide and you couldn’t see the blowhole at all. 

Also, the viewing area is very clearly walled off to discourage people from climbing down to get closer to it, but there’s always a few people that don’t think that applies to them. People get sucked into blow holes or overpowered by a rogue wave and swept out to see ALL THE TIME. Watch from a safe distance. 

There’s also a popular cove beach just south of the overlook (you’ll usually see plenty of people down there) that’s pretty picturesque. 

Makapu’u Point and Trail

This is a great easy/beginner hike with a big payoff of great views at the top. 

You’ll see a turn off with cars parked along it and a small parking lot at the bottom. It’s a mile hike (at a decent incline) to get to the top (where you can see a lighthouse plus epic views of the windward coast), but it’s entirely paved. I did this in flip-flops, although I wouldn’t really recommend it. It’s an easy enough hike, but a pretty good incline going up. The hike only takes about an hour, but bring plenty of water because there’s not really any shade. 

Waimanalo Beach

Also known as Sherwood Beach, this is a beloved local beach with a more low key atmosphere than other nearby popular beaches. And the backdrops are pretty lovely. 

Lanikai Beach

THIS is why you come to Hawaii. Regularly found on lists of world’s greatest beaches, Lanikai is picture perfect. It’s not the most convenient beach, but it’s worth it. Lanikai is a small neighborhood right next to Kailua Beach Park and there’s not much parking. There’s no parking allowed on the side of the street with the bike path, and you obviously can’t park in people’s yards or driveways, so you may have to hunt for a spot (or park at Kailua Beach and walk over). You also won’t find any amenities at this beach, so pack in (and out) everything you’ll need.

In recent years, Lanikai has become REALLY popular and it’s created a strain on the local community. At this beach (maybe more so than any other on Oahu), you’re accessing through a neighborhood so just be respectful of people’s space. 

Side Note: If you’re looking for a rental car for your trip, I LOVE Discount Hawaii Car Rentals. They’re seriously the only company I ever use. They’ll give you the very best prices, you don’t have to reserve with a credit card or pay until you show up, you can cancel and re-book anytime if you find a better rate, and they usually have a special that adds additional drivers for no fee. It’s a no brainer. Click here to check rates for your trip.

Kailua Beach

While next-door Lanikai beach is the island’s crown jewel, Kailua beach isn’t exactly the ugly stepchild. It’s gorgeous! And it has great amenities. You’ll find restrooms, showers, picnic areas, rentals, and the Kalapawai Deli. There’s also plenty of shade. 

Lanikai Pillbox Hike

There are so many hikes on Oahu, but this is my favorite! It’s fairly short, but it’s got a good pay off. You’ll find the trailhead on Kaelepulu Drive in Lanikai. All of the parking is on the road and it’s super limited. Be sure to respect the signs of where you’re allowed to be and where you’re not and don’t go traipsing through people’s yards.

This hike only took me about an hour up and back, but you really have to scramble in some places. The first part is by far the steepest. Most people stop when they reach the first pillbox, but you can keep going if you want to see them all. 

Kayak to the Mokulua Islands

If you love to kayak, paddleboard, or are just looking for an ocean adventure, you’ve got to paddle over to the “mokes.” Just a 30-minute paddle from Lanikai beach, there’s a small beach to land on and a whole lot of fun to be had. You can rent kayaks in Kailua, but the best place to launch them from is Lanikai. I haven’t done this yet, but I enjoyed reading this post about kayaking over on Memorial Day.

Shopping in Kailua

Kailua has so many cute boutiques but my favorites are on Hekili Street. It’s a great little strip with tons of cute boutiques and snack spots. Bikini Bird is one of my favorites. 

Breakfast at One of Kailua’s Popular Spots

Cinnamon’s is probably the most popular and talked about breakfast spot on the island (at least in Kailua). They’re famous for their pancakes, and the guava ones are my favorite. Go early (when they open) or expect to wait in line. They’ve recently opened up a location in Waikiki. Boots and Kimo’s is another famed spot best known for the macadamia nut sauce they put on their pancakes. Again, go early or expect to wait in line.

My personal favorite spot is Moke’s Bread and Breakfast. It doesn’t get the attention that Cinnamon’s or Boots and Kimo’s gets, but it’s fantastic. The best lilikoi pancakes period.

Get Shave Ice at President Obama’s Favorite Spot

Island Snow is rumored to be Barack Obama’s favorite shave ice spot on the island and it just so happens to be mine. It’s not far from Kailua Beach.

On Another Note: If you’re looking for a condo or vacation rental for your trip, I always book with Vrbo. They’ve got the largest selection of rentals you’ll find anywhere and you can easily filter to find exactly what you’re looking for. Need a specific number of bedrooms and bathrooms? Narrowed it down to a certain location? Want flexible cancellation terms? Need to stay under a fixed budget? Click here to search for Oahu vacation rentals for your trip.

Ho’omaluhia Botanical Garden

Just north of Kailua in Kaneohe you’ll find the Hoʻomaluhia Botanical Garden. Admission is free and the gardens are lovely, but the real star is the drive back to the gardens. The mountains are beautiful and seem to rise up right in front of your vehicle.

Haleiwa Joe’s

I think this is the best spot for a nice dinner on Oahu and the place that’s probably most comparable to Mama’s Fish House on Maui (although still not in the same league). The location in Kaneohe (Haiku Gardens-not to be confused with the one that’s actually in Haleiwa) is one of the loveliest spots on Oahu, the food is delicious, and the atmosphere feels special but not pretentious. It’s a favorite spot with locals to celebrate special occasions.

Kaneohe Bay Sand Bar

The sandbar in Kaneohe Bay has long been a favorite spot for locals who have boats to hang out on the weekends, but recently there has been a rise in tour operators who offer an adventure option for visitors. This is high on my list of things to do next time I’m on the island. 

Leaving Kaneohe and driving north, you’ll find yourself on THE best drive on Oahu. The drive along the windward coast towards the north shore is one of my favorite things to do on Oahu. You’ll be sandwiched between majestic green mountains on one side and stunning white sand beaches on the other.

Kahana Bay

This beautiful bay is such a gorgeous spot to pull over and stretch your legs. 

Mokolii Island (Chinamans Hat)

Pull over at Kualoa Park for great views of this funny shaped island just offshore. You can kayak out to Chinaman’s hat and hike to the top, but I wouldn’t say it’s an adventure for beginners. If you’re interested, find more info and book a rental here

Kualoa Ranch


We’ll end our adventures on this side of the island with one of Oahu’s biggest tourist attractions. “Tourist attraction” can sound like a dirty word, but I think Kualoa Ranch is a don’t miss. In the last 30 years, Kualoa Ranch has become Hollywood’s go to filming destination when they need a tropical jungle with breathtaking mountain views. 

The ranch really is incredible, and there are so many ways you can experience it. My personal favorite is the Jurassic Adventure Tour and I can’t recommend it enough. Read all about Kualoa Ranch here.

Everything You Need to Know BEFORE You Go to Oahu

Here’s one more really important thing you need to know before your Hawaii trip…

Reservations You Need to Make BEFORE Your Hawaii Trip

You’ve got your airfare, hotel, rental car and your big activities booked, so you should be good to go, right? Wrong!

Travel is BOOMING in Hawaii so a lot of state and national parks used the closure and reopening to institute reservation systems at some of the island’s most popular spots to make things a little more sustainable.

That means that there are now over half a dozen sites (beaches, trailheads, etc.) that require advance reservations. And some sell out well before you arrive on the island so you really need to have some sort of a plan.

I recently saw somebody in a Hawaii travel group post in a panic that they didn’t know they had to make reservations for things in advance…they thought they could just show up and “go with the flow.” I was tempted to say, well, “as long as the flow doesn’t take you somewhere that requires reservations, you can!” ; )

But I don’t want YOU to be that person, so I’ve pulled together a list of all the places you need to reserve entry in advance (plus all the details on booking windows, price, links, etc.) and a handful of popular tourist hotspots that book out really far in advance too.

Haleakala National Park (Maui)

To visit Haleakala National Park for sunrise at the summit, you must make reservations in advance here.

Reservations are required to enter the park gates between 3AM and 7AM (sunrise hours).

Online reservations are $1 per reservation/vehicle PLUS you’ll pay the park entrance fee of $30/vehicle when you arrive (National Park annual passes are also accepted at the gate).

The reservation booking window opens 60 days in advance at 7AM HST. There are also a limited number of tickets released two days before.

You can make one reservation every three days with the same account. So if you want to make reservations for back to back days (in case of weather/conditions), you’ll need to do so with separate accounts (email addresses).

If you can’t get reservations for sunrise, you can enter the park anytime after 7AM without reservations. The summit is spectacular during the day and you don’t need reservations for sunset.

I strongly recommend creating an account before and making sure you’re logged in at 7AM HST because it’s not uncommon for reservations to sell out quickly.

Waianapanapa State Park (Maui)

To visit Maui’s famous black sand beach at Waianapanapa State Park on the Road to Hana, you must make reservations in advance here.

Reservations are required to visit the beach and are distributed in windows from 7AM-10AM, 10AM-12:30PM, 12:30PM-3PM, and 3PM-6PM. And they are pretty strict about exiting by the end of your window time (you can arrive anytime within your window).

It’s $5/person to enter plus $10/vehicle to park and those fees are paid when you book your time slot.

Reservations open up 30 days in advance.

Iao Valley State Park (Maui)

To visit the lush, green mountains and hike at Iao Valley State Park, you must make reservations in advance here.

Reservations are offered for 90 minute time slots beginning at 7AM and ending at 6PM. They ask that you arrive within the first 30 minutes of your time slot.

Entry is $5/person plus $10/vehicle to park.

Reservations open up 30 days in advance.

Diamond Head (Oahu)

To hike to the top of Waikiki’s famous Diamond Head, you must make reservations in advance here.

Reservations are offered in two hour increments beginning at 6AM (6AM-8AM, 8AM-10AM, etc.) and ending at 6PM. If you’re parking onsite, they ask that you arrive within the first 30 minutes of your reservation window.

Entry is $5/person plus $10/vehicle to park.

Reservations open up 30 days in advance.

Tip: I recommend booking one of the first two time slots because there isn’t much shade on this hike and it gets pretty hot.

Hanauma Bay (Oahu)

To snorkel at Oahu’s pristine Hanauma Bay, you must make reservations in advance here.

Entry times are staggered in 10 minute increments from 7AM to 1:20PM with roughly 1000 slots being assigned in advance every day.

Reservations can be made two days in advance and they open at 7AM HST. They’re usually gone in minutes (if not seconds).

If you’re unable to get an advanced reservation, you can try for a day of, walk in ticket. They open at 6:45AM and they only have a limited number available. Everyone in your group needs to be present when you purchase your tickets in person.

There are no reservations for parking and it’s first come, first serve. $3/vehicle.

It’s $25/person to snorkel at Hanauma Bay (12 and under, active military, and locals with HI ID are free).

The Hanauma Bay Nature Preserve is open Wednesday through Sunday (CLOSED MONDAY AND TUESDAY) from 6:45AM-4PM. Last entry is at 1:30PM, the beach is cleared at 3:15PM and you have to leave the facility by 4PM.

Jellyfish patterns can also affect whether or not the bay is open so double check the day before/day of.

USS Arizona at Pearl Harbor (Oahu)

If you want to take the boat tour at Pearl Harbor out to the USS Arizona, it’s recommended to make advance reservations here.

Online reservations are guaranteed a specific boarding time to go out to the USS Arizona. If you’re unable to get an advance reservation, you can wait standby when you arrive. The line could be short (15 minutes or so) or long (hours) and it just depends on the day (if they’re having problems with the loading dock sometimes they don’t take many from the standby line) and the time of day.

Reservations are supposed to open up 60 days in advance, but keep an eye on your exact dates, because lately they’ve actually been opening up about 57ish days in advance???

They also release a small batch of tickets the day before.

The boat ride out to the USS Arizona is free, but it’s $1 to make the reservations online.

They recently started charging $7/vehicle for parking at Pearl Harbor.

Haena State Park / Kalalau Trail (Kauai)

If you want to hike Kauai’s famous Kalalau Trail, you must make advance reservations here.
You’ve got three options here:

1) Parking & Entry: This is the most flexible option and also the most limited. THESE RESERVATIONS SELL OUT IN LESS THAN A MINUTE. There are three time slots available: 6:30AM-12:30PM, 12:30PM-5:30PM and 4:30PM to sunset. You can purchase multiple time slots if you want to stay longer. It’s $10/timeslot (parking) plus $5/person and you have to reserve every person when you initially book. Everybody has to arrive in the same car and your ID needs to match the reservation.

2) Shuttle & Entry: If you can’t get parking at the trailhead, there’s also a shuttle option. Shuttle reservations are $35/person (16+), $25/person (ages 4-15), 3 and under can ride free. The shuttle runs every 20 minutes 6:20AM to 6:40PM.

3) Entry Only: If you’re a Hawaiian resident (with HI ID) or someone WITH a Hawaiian resident, you can purchase entry only for $5/person with no advance reservations. Also, if you’re walking or biking to the trailhead you can do this option. But there is NOWHERE to park in the area to walk in. So this really only works for those with bikes or who are staying close enough to walk. They will tow your car if you park outside the designated areas.

The reservation window opens 30 days in advance at 12AM HST. The parking & entry option usually sells out in a minute, but the shuttle availability will last longer.

There are a TON of FAQs here including the possibility of snagging a canceled reservation.

Other Things to Book in Advance

Hawaii is a busy place these days! Besides the state and national parks above, here’s a handful of miscellaneous things you should make reservations for in advance (if they’re on your radar):

Mama’s Fish House (Maui): The iconic spot is the most popular restaurant in Hawaii and dinner reservations usually start filling up about 6 months in advance (they open up bookings 18 months in advance). Make reservations through their website and if the dates you want are already booked, you can join a waitlist. Most people have pretty good success getting in on the waitlist (even if it’s for lunch).

Old Lahaina Luau (Maui): Honestly, any luau you’re planning to attend you should book early, but most people are usually shocked how far out the Old Lahaina Luau books out. Book it as soon as you know your dates (I think they open at the six month window). They also have a waitlist.

Kualoa Ranch UTV Tour (Oahu): Everybody loves Jurassic Park so getting to ride UTVs where they filmed the movies is very popular. The ranch offers a lot of different tours but the UTV tours usually book out a couple of months in advance.

Spa Reservations: If you’re staying at a resort with a spa (or planning on visiting one), don’t wait until you arrive to make your reservations. I’d make them at least a month in advance.

Tee Times: Same for golf, reserve your tee times well in advance.

Dining Reservations: Any “fancy” or resort restaurant is likely to be booked up these days so if you like having a nice dinner every night, make your plans in advance.
