Kona, on the Big Island of Hawaii, is a paradise for snorkeling and diving enthusiasts. Its crystal-clear waters teem with vibrant marine life, offering unforgettable underwater experiences regardless of your skill level. From beginner-friendly snorkel spots to advanced dive sites, Kona has something for everyone who dreams of exploring the ocean’s depths and discovering all of its beauty.
Why Kona is a Scuba Diving & Snorkeling Hotspot
Kona’s appeal as a premier dive destination stems from a few key factors. First, the consistently calm and clear waters provide exceptional visibility, often exceeding 100 feet. This allows you to fully appreciate the dazzling array of coral reefs and the creatures that call them home. Second, Kona enjoys year-round warm water temperatures, typically ranging from 75 to 82 degrees Fahrenheit, making even extended dives incredibly comfortable without heavy exposure suits for much of the year. Finally, the volcanic coastline, shaped by ancient lava flows, has created unique underwater formations, including lava tubes, arches, and caves, adding an extra layer of excitement to every dive.
Snorkeling Paradise: Must-Visit Spots for All Levels
Kahalu’u Beach Park: The Perfect Beginner’s Paradise: This is probably the most popular snorkeling spot on the Kona coast, and for good reasons. Kahalu’u Bay is protected by a natural lava rock barrier, creating a calm, shallow lagoon that’s ideal for beginners and families with young children. The water is usually very clear, and you’ll see a wide variety of colorful fish, including parrotfish, tangs, and butterflyfish. Keep an eye out for sea turtles (honu), as they frequently graze on the algae in the bay. To park, the entrance to the park is off Ali’i Drive. Parking can be limited, especially during peak hours, so arrive early. Look for parking along Ali’i Drive, or use free parking available, and plan for possibly a short walk. It’s entirely free to snorkel at Kahalu’u Bay, though you might choose to rent gear. Rental equipment is typically available for around $10-$15USD. Remember that sunscreen is vital to protect sensitive skin from the sun’s UV rays. You can even review park amenities and more details here.
Captain Cook Monument (Kealakekua Bay): History and Underwater Beauty: While getting here requires a bit more effort, the payoff is well worth it. Kealakekua Bay is a historical site and a marine sanctuary. The snorkeling here is phenomenal, with vibrant coral reefs and abundant marine life. You can reach the monument by boat tour, kayak, or a challenging 4-mile round-trip hike. Boat tours often include snorkeling gear and lunch, and it can be a convenient way to access the bay if you’re not up for a hike. If you opt for the hike, be sure to bring plenty of water and wear sturdy shoes. Snorkeling here gives you the chance to swim with dolphins, see manta rays gliding through the water, and observe the diverse coral formations. Multiple tour operators provide excursions to Kealakekua Bay, and the cost varies widely depending on the operator and the duration of the tour. Expect to pay somewhere between $100-$180USD per person for a half-day snorkeling tour. Before the snorkel, plan for a possible hike as well.
Honaunau Bay (Two Step): Easy Access to Incredible Reefs: Nicknamed “Two Step” because of the easy entry point using two natural steps carved into the lava rock, Honaunau Bay offers some of the best snorkeling on the Kona coast. Even the shallow waters near the entry point are teeming with fish, and as you venture further out, you’ll encounter stunning coral formations and a chance to see larger marine animals such as eels and octopus. The visibility is typically excellent, and the water is calm, making it a great spot for snorkelers of all skill levels. While there is little to no sand, the easy access, combined with the incredible underwater scenery, makes it a must-visit spot. The park is located off Highway 160 near the Pu’uhonua o Honaunau National Historical Park. The entrance involves some rocks, however, the snorkeling itself is very rewarding. There are usually food vendors around for refreshments, so it makes for smooth sailing. Make sure you’re up to date on the park’s potential closures.
Magic Sands Beach Park (La’aloa Beach Park): Surf and Snorkel in One Location: Known for its disappearing sand, Magic Sands is a popular beach park that offers both swimming and snorkeling opportunities. During the winter months, the surf can be high, making it ideal for bodyboarding and surfing. However, during the summer months, the waves calm down, making it a great spot for snorkeling. The reef is located close to shore, and you’ll be able to see a variety of colorful fish. There are also restrooms, showers, and picnic tables available, making it a great place to spend the day. You’ll find it along Ali’i Drive, south of Kailua-Kona. Keep in mind that the sand can disappear quickly due to strong wave action, so check the conditions before you go. Look for fish and other marine life and be mindful of the surf conditions. It’s a great spot for fun and convenience all in one.
Diving Deep: Kona’s Top Dive Sites
Manta Village: Witness the Night Ballet: Kona is world-famous for its manta ray night dives, and the Manta Village dive site is the epicenter of this incredible experience. Divers and snorkelers gather after sunset to witness these gentle giants feeding on plankton attracted by spotlights placed on the ocean floor. As you descend into the inky blackness, you’ll be surrounded by these graceful creatures, some with wingspans exceeding 12 feet. The experience is truly magical, and it’s something you’ll never forget. Numerous dive operators offer manta ray night dives, and the cost typically ranges from $150-$200USD per person.

The water is usually calm and clear, and there are plenty of fish and coral to see. You can explore the pilings under the pier, which are covered in marine life, or venture out to the nearby reef. It’s a great spot for macro photography, as you’ll find a variety of nudibranchs, crabs, and shrimp hiding among the coral. Parking is available near the pier, but it can be limited. You can enter the water directly from the beach or from the pier itself. Divers sometimes gather around the pier to see the various fish and other marine life. Before arriving review the current conditions of the pier to be respectful of any local closures.

The crater floor is covered in colorful coral formations, and the steep walls of the crater are home to a variety of marine life, including eels, octopus, and reef sharks.

The area requires a boat and is often best suited for experienced divers.
The Aquarium: A Gentle Drift Dive: The Aquarium is a shallow reef dive, perfect for beginners or those who want a relaxing dive with amazing visibility.

Essential Gear for Snorkeling and Diving
Having the right gear can make all the difference in your snorkeling or diving experience. For snorkeling, you’ll need a mask, snorkel, and fins. Make sure the mask fits snugly and creates a good seal around your face. Fins help you move more efficiently through the water, allowing you to cover more ground and conserve energy. A rash guard or wetsuit can provide protection from the sun and keep you warm in cooler waters. Bring along reef-safe sunscreen to protect your skin without harming organisms in the water.
Scuba diving requires a more extensive set of equipment, including a wetsuit, BCD (buoyancy control device), regulator, dive computer, and mask and fins. Depending on the dive, you may also need additional equipment such as a dive light, a dive knife, and a SMB (surface marker buoy). Ensure you are diving with properly maintained equipment that is inspected and in good working condition. Renting high quality gear is a must.
Tips for a Safe and Enjoyable Experience
Respect Marine Life: Remember, you are a visitor in the underwater world. Avoid touching or disturbing coral or marine animals. Maintain a safe distance from wildlife and never feed the fish, as this can disrupt the natural ecosystem.
Be Aware of Your Surroundings: Pay attention to the weather and ocean conditions before entering the water. Be mindful of currents, tides, and wave action. If you’re diving from a boat, listen carefully to the dive briefing and follow the instructions of the divemaster.
Know Your Limits: Don’t push yourself beyond your comfort level or skill level. If you’re a beginner, start with easy snorkel spots or guided dives. If you’re an experienced diver, choose dive sites that match your experience and training.
Stay Hydrated: Drink plenty of water before and after snorkeling or diving to avoid dehydration.
Buddy Up: Always snorkel or dive with a buddy, and stay within sight of each other.
Sun Protection: The Hawaiian sun is intense, so protect your skin with reef-safe sunscreen, a hat, and sunglasses. Wear a rash guard or wetsuit for added protection.
Practice Buoyancy Control: Good buoyancy control is essential for safe and enjoyable diving. Practice achieving neutral buoyancy so you’re not bumping into coral or stirring up sediment.
Responsible Snorkeling and Diving: Protecting the Reefs
Hawaii’s coral reefs are fragile ecosystems that are threatened by pollution, climate change, and unsustainable tourism practices. It’s important to snorkel and dive responsibly to minimize your impact on these precious environments. Choose reef-safe sunscreen that doesn’t contain harmful chemicals like oxybenzone and octinoxate. Avoid touching or disturbing coral or marine animals. Don’t litter or leave any trash behind. Support local businesses and organizations that are working to protect the reefs.
Here are some great alternatives to using traditional sunscreens:
- Badger Balm
- Mama Kuleana
