Oahu is paradise. The number of beaches to visit, hikes to choose from and adventures to go on are endless. You can be sure that there will be no shortage of things do to on Oahu, the challenge, however, will be choosing what to do. This blog covers the things that you must do on Oahu.

Visit Kualoa Ranch

Kualoa Ranch is considered the world’s most famous Private Nature Reserve, with over 50 movies and TV shows filmed here over the years. Visitors can choose from a range of guided tours and activities such as zip-lining, ATV tours, jungle expedition tours, movie site tours and horseback riding tours.

I took the Movie Site Tour and absolutely loved it. So many of my favourite movies and shows such as 50 first dates, Jurassic Park, Hawaii 5 0, Soul Surfer and Godzilla have been filmed here.

Ride a submarine scooter around the ocean floor

This was by far one of the coolest things I have done. Your head goes into a submarine tank as you submerge yourself to the ocean floor. You are sitting on a seat and can steer yourself around the ocean floor, with all the rainbow fish and turtles. This was an experience like no other.

Hike the Lanikai Pillbox Trail

The Lanikai Pillboxes hike is one of the most scenic hikes on the island, offering views over Lanikai Beach and the offshore islands of Na Mokulua. Pack water and some snacks because when you get to the top you won’t want to come down. See my guide to hiking Lanikai Pillboxes.

Relax on Lanikai Beach 

Lanikai Beach has white powder sand, crystal clear blue waters and a stunning view of the twin islands of Na Mokulua offshore, making it the most picturesque on the island (in my opinion).

Kailua Beach Park

Equally as beautiful as Lanikai Beach and in my opinion better because it is generally less crowded. Like Lanakai, Kailua Beach has white powdery sand, perfect waters and an incredible view.

Snorkel at Hanauma Bay

Anyone that has been to Hanauma Bay will tell you… DO NOT MISS IT! Hanauma Bay offers some of the best snorkelling conditions on the island, with an abundance of rainbow fish and turtles to swim with. Entry into Hanauma Bay is $7.50 and you can hire a snorkel for $20.

I recommend buying a snorkel from Walmart and taking it everywhere you go on the island.

Tips: Arrive early as it gets crowded. As per usual, I suggest packing a picnic to enjoy in the bay.

Hike the Koko Head Crater Trail

This is a short but extremely steep hike made up of 1042 stairs. The trail follows the old tram line directly up the side of the volcano. The stairs are uneven and should be done slowly and with caution. One section of the trail has caved out underneath the tram line so there is a 10ft drop below the tram line. If you are afraid of heights I would give this one a miss, but if you can overcome that fear, you won’t regret it. The view from the top is unreal.

Makapu’u Beach and lighthouse trail

The most scenic drive on the Island is between Hanauma Bay and Kailua. Around mid way, you will come across Makapu’u Beach and lighthouse. Makapu’u beach is beautiful, and so is the view from the lookout above it. You can choose to stop at the lookout for some photos of Makapu’u and the offshore islands or can take the lighthouse trail to an even higher lookout. The is an easy, 2-mile paved hike that can be done in an hour, round trip. Makapu’u is also popular for its tide pools and blowhole.

This hike isn’t for the faint-hearted. It takes you across a ridge with steep drops on either side and up rock walls of around 3 metres high. See that ridge below, that is what you will be hiking along. The view from the top is stunning and is guaranteed to get your adrenaline pumping.
