Best Snorkeling in Hawaii: Big Island, Maui, and Oahu
If you’re looking to swim with sea turtles and beautiful coral, these are the best places to visit in Hawaii for snorkeling.
Imagine snorkeling the warm waters of Hawaii as a sunny school of yellow tang flashes past. You kick your flippers, and a moray eel tucks into its crevasse between the coral while a large sea turtle slowly cruises past. Pack your swimsuit and reef-safe sunscreen and get going!
The Big Island has vast stretches of corals making it a snorkeler’s heaven, Maui is known for its popularity with sea turtles, and Oahu has one of the best snorkeling beaches in the United States. Every island has fantastic snorkeling for beginners to experts, and conservation areas like Molokini Crater and Hanauma Bay ensure plentiful wildlife sightings.
From white-sand beaches to lava-rock coasts, many of Hawaii’s top snorkeling spots are accessible from the shore, but to reach some of Hawaii’s prime snorkeling locations, you’ll need to go by boat. Plenty of snorkel tour operators are happy to take you out for a full-day or half-day adventure and often bundle together other fun activities, such as dolphin watching, kayaking, or surfing lessons.
Snorkeling the Big Island
Kahalu’u Beach Park
Shallow water makes Kahalu’u Beach Park perfect for beginner snorkelers, and the abundance and tameness of the sea life keeps veteran snorkelers coming back for more. Just a short walk from the historic town of Kailua-Kona, this volcanically formed beach has a few sandy places that let you easily enter the water with your fins on. While snorkeling at Kahalu’u Beach Park you’re likely to spot sea turtles feeding on seaweed or sunning on the lava rocks. When the tide goes out, carefully peer into the tide pools to see who stayed behind, such as hermit crabs, sea stars, and sea urchins.
Amenities include restrooms, showers, picnic tables, and a life guard on duty. Keep in mind that the parking lot tends to fill up fast, so it’s best to get there early.

Glide over a vast expanse of coral reef teeming with tropical fish in the calm waters of Kealakekua Bay State Historical Park. From the parking area, a steep hour-long hike takes you down to the Captain James Cook Monument where you can slip into the water. Travel by catamaran for a more relaxing journey as leaping spinner dolphins accompany you to this amazing snorkeling location.

Night Snorkel with Manta Rays
Join a thrilling night snorkel to swim with manta rays as they gracefully backflip to feed on plankton just below your fins. Giant manta rays can grow to 3,000 pounds (1,360 kg), but these gentle relatives of sharks are harmless to humans. Learn about these magnificent creatures from your knowledgeable guide as you sail into the Pacific sunset. Then, don your snorkel gear and hold onto a lighted flotation device that illuminates the wide wingspans of the manta rays below. Swimming with manta rays in Hawaii is a magical, moonlit experience for the whole family.

Snorkeling in Maui
In the crystal-clear waters of Hawaii’s longest fringing reef, you’re sure to see dozens of colorful fish darting around coral while snorkeling Molokini Crater. You’ll have to get to Molokini by boat since it’s located 3 miles (4.8 km) off the coast of Maui, but along the way, keep your eyes open for playful dolphins, stately whales (December to April), and nesting seabirds around this protected sanctuary. Trade winds tend to kick up in the afternoon, so head to this crescent-shaped volcanic crater in the morning for calm water suitable for beginner snorkelers.
If you’re scuba certified, don’t miss a chance to scuba dive Molokini. Explore the crater’s back wall and keep an eye out for endemic species like Hawaiian garden eels, masked angelfish, and longnose hawkfish.
- Sea turtles
- Whales (December–April)
- White-spotted puffer
- Picasso triggerfish
- Reef sharks (don’t worry, they’re harmless to humans)
Snorkel over lava rocks formed by submarine volcanoes on Maui’s southern coastline between Nahuna Point and Oneuli Beach. Honu (Hawaiian green sea turtles) love this area earning it the nickname Turtle Town. The sea turtles come to get their shells cleaned by surgeon fish and munch on marine greens making it one of the best places in Hawaii to swim with sea turtles. Launch from the uncrowded Maluaka Beach—which can be hard to find—or skip the navigational stress and snorkel with a local guide.

- Moray eels
- Humuhumunukunukuapua’a (Hawaii’s state fish)
Intermediate snorkelers will find unique coral formations around the Marine Life Conservation Area on Maui’s northwest shore. Known as Honolua Bay, this rocky beach is a great place for spotting lots of sea creatures below the water and surfers above. Waves get gnarly during the winter months, so swap your snorkel for a surfboard and have at it.

Snorkeling in Oahu
Hanauma Bay Nature Preserve
One of the best beaches in the United States for snorkeling, Hanauma Bay welcomes an average of 3,000 visitors each day. Even so, you can still find a spot on the white sand to lay out your towel before wading into the shallow turquoise waters. This volcanic crater on Oahu’s east side protects swimmers from ocean swells, making it one of the best snorkeling locations in Hawaii for beginners. Magnificent coral provides lots of crevices for fish to peek out from and you can get a good look as the wildlife is accustomed to visitors.
Hanauma Bay is an easy drive by car, but get there early since the parking lot fills up fast. No car? No problem! Take a shuttle from your Waikiki hotel and bundle it with snorkel gear rental to save even more time. When you arrive at the bay, be sure to check in at the marine education center to learn how to help preserve marine life.
Expedia Local Expert tip: The beach closes every Tuesday to give the sea life a rest.

Swim with Sharks
While another popular snorkel spot on Oahu is called Sharks Cove, you’re highly unlikely to actually encounter a toothy beastie in the water there. However, if aquatic predators are your thing, then sign up to swim with sharks in Hawaii. During your shark excursion, you’ll float at the surface in a metal cage as sharks circle mere inches from the bars. With your snorkel and mask, get a good look at some of the 40 species of sharks that inhabit the waters of Hawaii on a heart-pounding adventure.
- Galapagos sharks
- Sandbar sharks
- Grey reef sharks
- Hammerhead sharks
Swim with Dolphins
Oahu has fewer snorkeling beaches compared to the other islands, but traveling by boat can take you to some excellent snorkeling locations. On your way, you’re likely to see spinner dolphins leaping from the waves in joyful, acrobatic displays. While it’s illegal to swim with wild dolphins, you can still fulfill your life-long dream of swimming with dolphins in Hawaii at Dolphin Quest or Sea Life Park in Oahu. Have a personal moment with a trained dolphin or learn to be a dolphin trainer for a day.
