Which Hawaii Island has the best Turtle Snorkeling? Oahu, Maui, Big Island or Kauai

Turtle snorkeling in Hawaiʻi is a bucket list experience, but not all islands offer the same opportunities. If your goal is to get in the water and swim beside a Hawaiian green sea turtle (honu), choosing the right island and the right beach, can make all the difference.

Maui and the Big Island are consistently rated as top destinations for turtle snorkeling, thanks to their calm waters and thriving marine habitats. But Oʻahu isn’t far behind and offers some standout tours, especially at Turtle Canyon. Let’s break down the best snorkeling destinations on each island with both in the water and from the shore.

1. Maui: The Undisputed Leader in Turtle Snorkeling

With its gentle currents, vibrant reefs, and clear visibility, Maui is widely considered the best island for turtle snorkeling. The island’s southern coast, especially, is home to some of the most reliable turtle encounters in the state.

Best In-Water Snorkel Spots:

Turtle Town (Maluaka Beach): A go-to location for swimming with sea turtles, especially during morning hours when the water is calm.
Honolua Bay: A protected marine preserve with coral reefs that attract turtles year-round.
Olowalu Reef: Often called “Coral Gardens,” this spot features shallow waters and a high chance of turtle sightings.

Best Land-Based Viewing:

Black Rock at Kaanapali Beach: A favorite for snorkelers and sunbathers alike.
Napili Bay: Calm waters make it ideal for beginner snorkelers.
Makena Landing: A good launch point for kayak-snorkel combos that often lead to turtle encounters.

2. Big Island: Wild Coastlines and Turtle-Filled Bays

The Big Island boasts the longest coastline in the Hawaiian chain, giving sea turtles plenty of space to thrive. The island’s diverse beaches, from black sand to rocky bays, host a variety of marine life, including frequent turtle sightings.

Best In-Water Snorkel Spots:

Honaunau Bay (Two Step): Crystal-clear water, lava rock entries, and turtle-friendly coral make this a top snorkel site.
Kahaluu Beach Park: Easily accessible and rich in both coral and turtle populations.
Kealakekua Bay: Famous for its snorkeling and occasional turtle sightings among spinner dolphins and reef fish.

Best Land-Based Viewing:

Punaluu Black Sand Beach: Turtles love to sunbathe here on the jet-black sand.
Richardson Ocean Park: Good for both snorkeling and shoreline viewing.
Carlsmith Beach Park: A lagoon-like area often visited by turtles near Hilo.

3. Oʻahu: An Underrated Turtle Snorkeling Destination

While Oʻahu is more famous for surfing and city life, it has some excellent snorkeling locations too, especially if you know where to look. The island ranks third, but it’s still a great place for unforgettable turtle encounters.

Best In-Water Snorkel Spot:

Turtle Canyon (Waikiki Area): This offshore reef is one of the top-rated places to snorkel with turtles on Oʻahu. Book with Turtle Snorkeling Oahu which is a 5.0-star reviewed tour company known for their expert guides and sustainable practices.

Makaha Beach: Known for its mix of snorkeling and surfing, and occasional turtle sightings near the reef.

4. Kauaʻi: Scenic But Less Reliable for Turtle Encounters

Kauaʻi is rich in beauty, from the Nā Pali Coast to Waimea Canyon. However, it’s not the best island for consistent turtle snorkeling. That said, you still might get lucky in a few spots.

Best In-Water Snorkel Spots:

Poipu Beach: Calm enough for families and beginner snorkelers, and occasionally visited by turtles.
Tunnels Beach: Offers beautiful reef formations and a chance to spot turtles.

Lawai Beach: A small but popular snorkeling area near Poipu.
Keʻe Beach: Great for scenery, and sometimes turtles swim close to shore.

Sea Turtles and Snorkels: The Ultimate Island Experience Awaits

Swimming with sea turtles is one of the most unforgettable experiences you can have in Hawaiʻi. Maui offers the most consistent encounters, followed by the Big Island’s remote charm. Oʻahu may surprise you with its quality spots, especially if you book a top-rated tour at Turtle Canyon.

No matter which island you choose, remember: turtles are protected under federal and state law. Look, don’t touch and always give them space in the water and on the shore.
