Hawaii is a paradise for snorkelers and divers, boasting some of the clearest waters and most vibrant marine life on the planet. From beginner-friendly bays teeming with colorful fish to challenging dives amidst ancient lava formations, there’s something for every level of experience. This guide will navigate you through the best snorkel and dive spots in Hawaii, covering each island’s unique underwater treasures.
Oahu: A Blend of Accessibility and Variety
Oahu, known as “The Gathering Place,” offers a fantastic introduction to Hawaiian snorkeling and diving. Its sheltered bays and accessible reefs make it ideal for beginners, while more experienced divers can explore deeper wrecks and offshore sites.
Hanauma Bay: The Iconic Snorkeling Haven
Hanauma Bay is undoubtedly Oahu’s most famous snorkeling spot. Formed within a volcanic crater, this protected bay is home to a vast array of colorful fish, including the iconic humuhumunukunukuapua’a (reef triggerfish), Hawaii’s state fish. The shallow, calm waters make it perfect for families and novice snorkelers. Before jumping in, you’ll need to watch a short video about reef conservation; this effort has significantly helped to protect the bay’s delicate ecosystem. Keep an eye out for sea turtles, often seen grazing on the sea grass. Entrance fees are usually around $25 per person (as of October 2024, but check the official Honolulu Parks & Recreation website for the most current pricing), and reservations are required. Parking can be a challenge, so arrive early (even before the official opening) or consider taking a shuttle.
Directions: Hanauma Bay is located on the southeastern coast of Oahu. From Waikiki, take H-1 East and follow the signs. The drive is approximately 30-45 minutes, depending on traffic.
Tip: Bring your own reef-safe sunscreen – it’s a must for protecting both your skin and the coral reef. Also, avoid standing on the coral, as it’s extremely fragile. Consider investing in a good-quality snorkel mask for a more comfortable and enjoyable experience. You can rent gear at the entrance, but bringing your own is often more hygienic and cost-effective.
Shark’s Cove: North Shore’s Summer Gem
During the summer months (May-September), when the North Shore seas are calmer, Shark’s Cove transforms into a fantastic snorkeling destination. Despite its intimidating name, sharks are rarely seen here. The cove is filled with lava rock formations creating numerous tide pools and shallow snorkeling areas teeming with marine life. It’s an excellent place to spot butterflyfish, tangs, and other reef fish. Conditions can be rough during the winter months (October-April), so be sure to check the surf report before heading out.
Directions: Shark’s Cove is located on the North Shore of Oahu, near Pupukea Beach Park. It’s approximately an hour’s drive from Waikiki. Parking is limited, especially during peak season, so arrive early.
Tip: Wear reef shoes to protect your feet from the sharp lava rocks. Be aware of the tides and currents, and avoid snorkeling in areas with strong currents. There are several dive shops nearby that offer snorkeling gear rentals and guided tours.
Electric Beach (Kahe Point): Warm Water Discharge Fun
Electric Beach, also known as Kahe Point, is unique due to the warm water discharged from the nearby electric power plant. This warm water attracts a variety of marine life, making it a popular snorkeling and diving spot. You can often see turtles, rays, and a wide array of fish here. The current can be strong, especially further out from the shore, so it’s best suited for confident swimmers. There are two entry points: the beach itself and a channel further north that provides an easier entry point with slightly less current.
Directions: Electric Beach is located on the west side of Oahu, near Nanakuli. From Waikiki, take H-1 West to Farrington Highway (Highway 93). It’s about a 45-minute drive.
Tip: Check the current conditions before entering the water. The current can be particularly strong during tide changes. Be aware of boat traffic, especially near the channel entry point. Consider using a dive flag to mark your location. Scuba diving is also popular at Electric Beach, and several dive shops offer guided tours.
For Divers: The Corsair and Sea Tiger Wrecks
Oahu offers several excellent wreck dives for experienced divers. The Corsair, a World War II airplane, lies in approximately 100 feet of water off the coast of Sand Island. It’s a popular dive site due to its fascinating history and the marine life that has colonized the wreck. The Sea Tiger, a former Chinese freighter, was intentionally sunk in 1999 to create an artificial reef. It’s now home to a thriving ecosystem of fish, turtles, and eels. The Sea Tiger is a deeper dive, typically around 120 feet, so it requires advanced diving certification. Several dive operators on Oahu offer trips to these wrecks.
Cost: Expect to pay around $150-$200 for a two-tank dive trip to the Corsair or Sea Tiger. This usually includes equipment rental and boat transportation.
A Note on Currents
Oahu’s currents can be unpredictable. Always check the local surf report and heed any warnings posted by lifeguards. If you’re unsure about the conditions, it’s best to err on the side of caution and choose a different location or postpone your snorkeling or diving trip.
Maui: The Valley Isle’s Underwater Wonders
Maui, known as “The Valley Isle,” is renowned for its exceptional snorkeling and diving, offering a diverse range of underwater experiences, from Molokini Crater to the vibrant coral reefs along its coastline.

Tip: Be cautious when cliff-jumping, and only jump from a height that you’re comfortable with. Check the water depth before jumping to avoid injuries. Wear reef shoes to protect your feet from the rocks. Be aware of boat traffic in the area.
For Divers: Mala Wharf
For divers, Mala Wharf is a truly unique experience. The pier was destroyed by a hurricane in 1992, and the wreckage has become an artificial reef, attracting a staggering amount of marine life. You’ll find schools of fish, sea turtles, white tip reef sharks, and even frogfish hiding amongst the debris. The average depth is around 25-30 feet, making it suitable for divers of all skill levels. Shore entry is easy, and the visibility is usually good.

Night Manta Ray Snorkel/Dive: An Unforgettable Experience
The night manta ray snorkel/dive is a must-do experience on the Big Island. Every night, manta rays gather off the Kona coast to feed on plankton attracted by spotlights shining into the water. Snorkelers and divers can observe these graceful creatures up close as they soar and glide through the water. It’s a truly magical and unforgettable experience. Several tour operators offer night manta ray snorkel/dive trips.
Cost: Night manta ray snorkel tours typically cost between $100 and $150 per person. Dive trips are usually more expensive, ranging from $150 to $250 per person, depending on the number of dives and equipment rental.
