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!

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.

Pearl Harbor is today home to many memorials commemorating the attack, including the USS Arizona Memorial and the USS Missouri Memorial, which both offer a somber look at the infamous day’s events.

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.

7. 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 like 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.

8. 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.
