The Hawaiian archipelago is one of the most adventurous destinations to visit in the United States, being home to spectacular tropical coastlines, smoldering volcanic craters and lush, green rainforests.
Each island is different though, and you’ll find that the four main islands each have their own vibes, their own different sights to see and their own unique cultural traits, which all add to the state’s immense diversity.
You can see active volcanoes on the Big Island, snorkel with turtles on Maui, explore canyons on Kauai, or discover the city of Honolulu and the history of Pearl Harbor on Oahu.
There are a lot of things to do in Hawaii, so to help you to plan your trip, here are our favorites!

Climb Diamond Head Crater
If you look along the length of Waikiki Beach, you can’t miss the staggering sight of the Diamond Head Crater. The enormous crater is one of the largest on the island and the hike to the summit is one of the best things to do in Hawaii.
The hike from the base of the volcano is steep, but there are many steps built along the trail to help you out. The hike takes around 2 hours round trip, so start early to beat the heat, and take plenty of water to keep you hydrated.

White sands line the shore, and dramatic cliffs rise high until they drop off into the clear, turquoise-blue water. It’s the perfect place for snorkeling, as the protected area is a haven for local species of fish and other marine wildlife which are found just off the beach.

Haleakala National Park
Maui’s most spectacular area of wilderness is found within the boundaries of the Haleakala National Park. The park is named for the massive Haleakala Crater, a volcanic crater that rises at its highest point to over 3000 meters in height.
The hike to the summit is one of the most arduous and challenging in Maui, but it’s one of the best things to do in Hawaii, as you’ll find yourself at high altitude and in otherworldly landscapes. If tackling the summit isn’t for you, then the national park is laced with different walking trails leading to smaller peaks, to valleys and to waterfalls.
Our top recommended tours including Haleakala National Park:
- Maui’s Best Adventure – Haleakala Bike & Zipline Tour
- Haleakala Sunset Tour and Dinner on Maui
- East Maui 45-minute Helicopter Tour over Haleakala Crater
Drive the Road to Hana
The Hana Highway is Maui’s eastern road that takes you from Kahului in the north to Hana in the east and then further south to Kipahulu. It’s one of the best road trips you can make in Hawaii, as the highway takes you past the best of Maui’s dramatic coastal scenery.
The east is nowhere near as built up as other parts of the island, and you’ll find yourself exploring isolated beaches and bays, discovering small coastal towns, villages and enjoying a quiet side of Maui that has been lost in the touristy areas.
We use Discover Car Hire for comparing car prices to find the best deal. They search both local & international rental companies.
Our top recommended tours including Hana Highway:
Luau Feast
One of the most cultural things to do in Hawaii is to experience a Luau. This traditional, Hawaiian style feast is a dinner of epic proportions, and across Maui, you can find some of the best Luau.
A Luau involves eating an extraordinary amount of food, with the centerpiece being a pig that’s been slow cooked in an earthen oven. These days, many of the Luau are aimed specifically at tourists, but that means that alongside the food you’ll be able to enjoy plenty of drinks as well as cultural performances from dancers and musicians.
Our top recommended tours including a Luau Feast:
Things to do in Kauai
Waimea Canyon
Waimea Canyon is one of the best things to do in Hawaii and this magnificent natural sight that’s located on the island of Kauai is absolutely beautiful to explore.
The canyon is formed by the Waimea River which cuts through the rock, and it’s vibrantly colored in different shades of red, orange and green. Known as the Grand Canyon of the Pacific, you have all manner of adventure opportunities awaiting you at Waimea, from helicopter rides to hiking tours.

The cliffs here are rugged and green, and the tallest rise to over 1000 meters in height. There are some excellent hiking trails through the valleys that lead to the cliffs, but one of the most exciting ways to experience Na Pali is by joining a thrilling helicopter ride along the coastline.
Wailua River
Another adventurous spot to visit in Kauai is the Wailua River, which is the island’s longest and arguably, most scenic river.
