So, you’ve just had an epic snorkeling session in Oahu? Maybe spotting green sea turtles in Waikiki, swimming through coral reefs at Hanauma Bay, or floating in the clear waters off the North Shore. Now what?
Oahu isn’t just a snorkeling paradise – it’s packed with unforgettable sights, cultural landmarks, and adventure-filled stops. If you’re wondering what to do after you’ve rinsed off the salt water, here’s your go-to list of the top attractions in Oahu to explore post-snorkel.
1. Pearl Harbor National Memorial – Dive Into History
Rated 5.0 by over 33,000 visitors, Pearl Harbor is one of the most important historical sites in the United States. Visit the USS Arizona Memorial, watch a short documentary, and walk through exhibits that tell the story of the attack that changed the course of WWII. It’s a moving, must-see experience that offers a powerful contrast to a day in the ocean.
2. Oahu North Shore – Surf Culture & Shrimp Trucks
Already snorkeled on the calm summer side? Head back in winter to see the North Shore transform into a surfing mecca with 40-foot waves. On land, grab a plate of garlic shrimp from a famous food truck, stroll through artsy Haleiwa Town, or hike to a waterfall. It’s the laid-back, local side of Oahu — and a total vibe.
3. Dole Plantation – Pineapple Paradise
Trade your snorkel gear for a scoop of fresh Dole Whip. The Dole Plantation is fun for all ages, offering a charming train ride through pineapple fields, a giant garden maze, and cool agri-tours. It’s a sweet stop that captures Oahu’s agricultural roots.
4. Diamond Head Crater – Best Hike for Views
You’ve seen it from Waikiki Beach — now hike it! The Diamond Head trail is a moderate climb with panoramic views of the coastline and Honolulu skyline from the summit. The 760-foot ascent is well worth the sweat.
5. Kualoa Ranch – Jurassic Adventure
Ready to trade fins for an ATV? Kualoa Ranch is an adventure-lover’s dream. Tour film sites from Jurassic Park, ride ziplines through the jungle, or paddle in a traditional Hawaiian fishpond. The ranch spans 4,000 lush acres and is one of the most versatile activities on the island.
6. Makapuu Lighthouse Trail – Easy Coastal Hike
If you’re looking for a low-key adventure with killer views, hit the Makapuu Point Lighthouse Trail. This paved path hugs the cliffs of Oahu’s windward side and ends with sweeping ocean views. In winter, you might even spot migrating humpback whales!
7. Halona Blowhole – Nature’s Ocean Geyser
Just minutes from Hanauma Bay, this natural lava tube sends water shooting up to 30 feet in the air when waves crash into the shore. The lookout also gives you a perfect panoramic view of the southeast coastline.
8. Waikiki – Endless Shopping & Nightlife
Back in Waikiki? Swap your snorkel mask for a sunset cocktail. With world-class dining, high-end shopping, street performers, and night markets, Waikiki is just as lively after dark as it is on the beach.
9. Sandy Beach Park – Watch the Pros
This beach isn’t ideal for casual swimming, but it’s legendary for bodyboarding and wave watching. The powerful shore break has earned it the nickname “Break Neck Beach,” so bring your camera, not your floaties.
10. National Memorial Cemetery of the Pacific (Punchbowl) – A Peaceful Tribute
For a quiet and respectful pause in your trip, visit Punchbowl Crater, the final resting place for thousands of veterans. The location offers historical insight and sweeping views of Honolulu from its hilltop position.
Oahu is full of incredible things to do beyond snorkeling — from epic hikes and historic landmarks to local eats and island-style adventures. Whether you’re exploring the coastline, diving into history, or chasing waterfalls, there’s always something new to discover after your time in the water.
Pro Tip: Plan your day with a snorkel spot in the morning and a nearby attraction or hike in the afternoon. That way, you get the best of both worlds — under the sea and above it.
