Hawaii’s marine environment is a treasure trove of biodiversity, offering visitors unforgettable encounters with some of the ocean’s most remarkable creatures. From vibrant coral reefs to majestic whales, here are the most incredible marine life experiences to have on your next trip to Hawaii.
1. Snorkeling at Hanauma Bay, Oahu
Hanauma Bay is a renowned marine life conservation area and one of Hawaii’s premier snorkeling destinations. Visitors can expect to see a dazzling array of fish, including the state fish, the humuhumunukunukuāpuaʻa, along with angelfish and butterflyfish. The bay’s clear waters and rich biodiversity make it an ideal spot for both novice and experienced snorkelers. Remember, the bay is closed on Tuesdays for conservation efforts, so plan your visit accordingly.
2. Exploring Molokini Crater, Maui
Located about three miles off the coast of Maui, Molokini Crater is a volcanic caldera famous for its crystal-clear waters and vibrant marine life. With visibility often reaching up to 150 feet, snorkelers can encounter moray eels, rays, and a plethora of tropical fish. The unique underwater landscape offers a captivating experience for divers and snorkelers alike.
3. Swimming with Manta Rays on the Big Island
The Kona Coast of the Big Island is famous for its nighttime manta ray encounters. Visitors can book tours to snorkel or dive with these gentle giants, which can have wingspans of up to 20 feet. The experience of watching manta rays glide gracefully through the water, illuminated by the glow of underwater lights, is truly magical and often cited as a highlight of any Hawaiian trip.

The best times of year to see manta rays on the Big Island
There isn’t a specific “best” time of year to see manta rays on the Big Island of Hawaii. Here are the key points about manta ray sightings throughout the year:
Consistency of sightings: According to data from one tour operator, manta rays show up over 80% of the time at popular viewing sites like Manta Ray Heaven / Garden Eel Cove.
Year-round sightings: Manta rays can be encountered in Hawaii throughout the year. There is no strict “season” for manta ray sightings.
Consistent presence: Unlike some other marine animals like humpback whales that migrate seasonally, manta rays spend their time around the island year-round and don’t venture too far away.
Summer preference: Manta rays tend to be more active in warmer weather and calmer waters. As a result, they are often seen more abundantly during the summer months (May to September).
Winter activity: While sightings may be less frequent in winter (January through March), manta rays are still present. The oceans can be rougher during this time, which may affect their visibility.
Nightly encounters: The best time to see manta rays is typically in the evening. Many tour operators offer night snorkelling or diving experiences, as manta rays are attracted to areas where lights are used to draw in plankton, their primary food source.
4. Dolphin Watching and Swimming
Hawaii is home to two main species of dolphins: spinner dolphins and bottlenose dolphins. Spinner dolphins are known for their acrobatic displays and can often be seen in pods off the coast of the Big Island and Oahu. Many tour operators offer dolphin-watching excursions, providing opportunities for close encounters with these playful creatures. Swimming with dolphins is a bucket-list experience for many visitors.
5. Whale Watching
From late November to early May, humpback whales migrate to Hawaii’s warm waters to breed and nurse their calves. Whale-watching tours are available throughout the islands, with Maui being a prime location for sightings. The experience of seeing these magnificent creatures breach and spout water is awe-inspiring and a must-do for nature lovers.
6. Encountering Hawaiian Green Sea Turtles
The Hawaiian green sea turtle, or honu, is an iconic species that can often be seen swimming in the waters around the islands or basking on the beaches. Popular spots for turtle sightings include Kahaluu Beach Park on the Big Island and various North Shore beaches on Oahu. Observing these gentle creatures in their natural habitat is a highlight for many visitors.
7. Discovering the Underwater World at Kealakekua Bay
Kealakekua Bay, known for its historical significance and stunning natural beauty, is also a fantastic snorkeling destination. The bay is a Marine Life Conservation District, teeming with colorful fish and coral. Visitors may also spot spinner dolphins here, making it a perfect location for marine life enthusiasts.
8. Exploring Tunnels Beach, Kauai
Tunnels Beach, located on Kauai, offers a unique snorkeling experience with its intricate reef formations. The diverse marine life includes butterflyfish, surgeonfish, and sea turtles. This spot is suitable for both beginner and experienced snorkelers, providing a captivating underwater adventure.
