Why the Big Island is Perfect for Sea Turtle Spotting
The Big Island of Hawaii isn’t just known for its active volcanoes, lush rainforests, and stunning black sand beaches — it’s also one of the best places in the entire state to see Hawaiian green sea turtles, or honu, in their natural habitat. Whether you’re traveling with family or adventuring solo, nothing compares to the experience of seeing these ancient creatures gracefully swim through the crystal-clear waters or bask lazily on sun-warmed sands.
Top Beaches to See Sea Turtles on the Big Island
Punaluʻu Black Sand Beach
Punaluʻu Beach is often considered the most reliable place to spot green sea turtles. Thanks to the warm volcanic-sand shore and abundant nearshore seaweed, honu are frequent visitors here. Located on the southeastern coast of the island, this beach’s shimmering black volcanic sand creates a striking contrast to the green-brown shells of the turtles.
Tip: Arrive in the morning or late afternoon to increase your chances of seeing turtles sunbathing. Make sure to keep a respectful distance — at least 10 feet — and never touch or feed the turtles.
Carlsmith Beach Park (Four Mile)
Located just a few miles from downtown Hilo, Carlsmith Beach Park is another excellent spot for safe and respectful turtle spotting. The calm tidal pools and shallow lagoons provide a safe haven for sea turtles to graze and rest, making this a perfect destination for families with kids. Don’t forget your snorkel and reef-safe sunscreen before heading into the water.
Kaloko-Honokōhau National Historical Park
On the Kona side of the island, this national park combines cultural history with biological diversity. The protected tidepools, fishponds, and sandy shores are often frequented by sea turtles. The beach area near the Aiʻōpio Fishtrap, in particular, usually has turtles both in the water and on land. While you’re there, you can also learn about traditional Hawaiian fishpond infrastructure and ancient coastal living.
Snorkeling with Sea Turtles
If you’re interested in snorkeling with turtles, head to Kahaluʻu Beach Park, minutes from downtown Kailua-Kona. The sheltered cove offers calm waters ideal for beginners, with abundant coral reefs and marine life. Turtles are often seen grazing in the shallow waters near the shoreline.
Before you dive in, make sure you’re wearing marine-safe sunscreen to protect both your skin and the sensitive coral environment. Products like those offered by Coco Botanicals are mineral-based, reef-safe, and ideal for families looking to explore responsibly.
Best Times of Day and Year to Spot Turtles
While sea turtles can be seen year-round on the Big Island, the best chances are during the warmer months between April and October. Time of day also matters — early mornings and late afternoons tend to be the most active times for turtles to feed or bask on the shore.
Important Guidelines for Responsible Turtle Watching
- Keep at least 10 feet (3 meters) away from turtles at all times.
- Never touch, chase, or feed them.
- Use only reef-safe, mineral-based sunscreen.
- Stay quiet and avoid crowded groups near turtles.
- Observe posted signs and park guidelines to help preserve turtle habitats.
Final Thoughts
The Big Island offers multiple family-friendly destinations for observing sea turtles in their natural environment. Whether you’re snorkeling in calm coastal lagoons or relaxing on a black sand beach, seeing a honu up close is an unforgettable experience — and a chance to connect with Hawaii’s unique natural beauty. Just remember to respect local wildlife and preserve the environment for generations to come by traveling responsibly.
