Best Snorkeling in Hawaii: Where to Go on Each Island
Each of Hawaii’s islands boasts its own distinct snorkeling experience. Some places are perfect for beginners, while others require a bit more effort to reach—but the reward is worth it. Here’s a breakdown of the best spots by island.
1. Best Snorkeling in Maui
Maui stands out as a prime snorkeling spot with its clear waters and thriving marine life. Whether you want to explore offshore craters or easy-access beaches, Maui delivers some of the best snorkeling in Hawaii.
Molokini Crater
Molokini, a renowned snorkeling spot in Hawaii, is a crescent-shaped volcanic crater off Maui’s coast, boasting visibility up to 150 feet. Since it’s a marine life conservation district, the waters are packed with colorful fish and even the occasional reef shark. Booking a snorkeling tour in Maui is the only way to access this spot, and it’s well worth the trip.
Honolua Bay
If you prefer snorkeling straight from shore, Honolua Bay is an excellent choice. This protected bay on Maui’s northwest coast is home to vibrant coral reefs and a huge variety of fish. It’s best to visit in the summer when the waters are calm.
Kapalua Bay
Kapalua Bay is a favorite for families and beginner snorkelers. The gentle waves and easy beach entry make it a stress-free place to explore. You’ll see plenty of tropical fish and, if you’re lucky, a Hawaiian green sea turtle.
2. Best Snorkeling on the Big Island
The Big Island offers some of the most diverse snorkeling experiences in Hawaii, from lava rock formations to historical bays filled with marine life.
Kealakekua Bay (Captain Cook Monument)
Kealakekua Bay ranks among Hawaii’s most breathtaking snorkeling destinations. The waters here are protected and incredibly clear, making it easy to spot vibrant coral and large schools of fish. This spot holds historical significance as the landing site of Captain James Cook in Hawaii. The best ways to reach it are by snorkeling tour, kayak, or a scenic hike.
Two Step (Honaunau Bay)
Two Step (Honaunau Bay) is a must-visit for experienced snorkelers. Located near Puʻuhonua o Hōnaunau National Historical Park, this spot is famous for its lava rock ledges, which make for an easy water entry. You’ll see parrotfish, moray eels, and even spinner dolphins if you go early in the morning.
Kahalu’u Beach Park
This is a great option for families and beginners. Located near Kailua-Kona, Kahaluʻu Beach Park offers shallow waters and a high fish population. It’s also an ideal spot for snorkeling lessons.
3. Best Snorkeling on Oahu
Oahu has plenty of fantastic snorkeling locations, whether you’re looking for a family-friendly beach or an off-the-beaten-path adventure.
Hanauma Bay
Hanauma Bay is globally recognized as a premier snorkeling destination. This nature preserve is home to over 400 species of fish, and the calm waters make it perfect for beginners. A small entry fee is required, and the park closes on Mondays and Tuesdays to help preserve marine life.
Shark’s Cove
Despite the name, Shark’s Cove isn’t known for sharks—but it is packed with marine life. This rocky cove on Oahu’s North Shore offers some of the best snorkeling in Hawaii for those who want to see caves, tunnels, and a huge variety of fish.
4. Best Snorkeling on Kauai
Kauai, known as the Garden Isle, has fewer snorkeling spots than other islands, but the ones it does have are spectacular.
Tunnels Beach (Makua Beach)
Tunnels Beach, part of Haʻena State Park, is one of Kauai’s best snorkeling spots, featuring an extensive coral reef system. The dramatic underwater landscape is perfect for exploring, and the visibility is excellent when the ocean is calm.
Poipu Beach Park
For a family-friendly snorkeling experience, Poipu Beach Park is the place to go. With its shallow waters, this spot is perfect for kids and is sometimes visited by Hawaiian monk seals.
Snorkeling Tips for a Safe and Fun Experience
Snorkeling in Hawaii is an incredible adventure, and a bit of planning can make it even more enjoyable.
- Use reef-safe sunscreen: Hawaii has strict sunscreen laws to protect coral reefs. Be sure to use sunscreen that’s labeled “reef-safe” and free of oxybenzone.
- Arrive early: Many snorkeling spots get crowded later in the day. Mornings also offer the best conditions, with calmer waters and better visibility.
- Check ocean conditions: Always look at the surf report before heading out. Some areas, especially in the winter, can have dangerous waves and currents.
- Respect marine life: Never touch the coral or chase sea turtles. Give wildlife plenty of space to keep the ecosystem healthy.
- Consider a guided tour: If you’re new to snorkeling or want to access the best spots, booking a Hawaii snorkeling tour can be a great way to enhance your experience.
Where to Rent Snorkeling Gear in Hawaii
If you don’t have your own snorkeling gear, renting is simple. Most popular tourist spots have rental shops with budget-friendly daily or weekly rates. Some top places to rent gear include:
- Boss Frog’s Snorkel Rentals (Maui, Kauai, Big Island)
- Snorkel Bob’s (Oahu, Maui, Kauai, Big Island)
- Hanauma Bay Snorkel Rentals (Oahu)
If you’re snorkeling for multiple days, investing in your own mask and snorkel can provide a better fit and more comfort.
