Seeing a Hawaiian green sea turtle, or honu, cruising through turquoise water or resting on a black sand beach is a core memory for many visitors to Hawaiʻi. These gentle, ancient creatures are a treasured part of the marine ecosystem and Hawaiian culture. The Big Island offers some of the best opportunities in the state to witness them, but it comes with a responsibility to view them safely and respectfully.

This guide will walk you through the best spots to find them, from famous “turtle beaches” to lesser-known snorkeling coves, and most importantly, how to be a courteous observer so these animals continue to thrive for generations to come.

Understanding Hawaiʻi's Sea Turtles

When you see a sea turtle on the Big Island, you’re most likely looking at a honu, the Hawaiian green sea turtle. They are the largest hard-shelled sea turtle in the world and can be seen feeding on algae (limu) in shallow waters or basking on the sand. You might also, if you are exceptionally lucky, spot the rarer and critically endangered hawksbill sea turtle, known as honu ʻea. They are distinguished by their narrower, bird-like beak.

Both species are woven into the cultural fabric of Hawaiʻi, appearing in creation chants and revered as ʻaumākua, or ancestral spirits, by some families. Their populations were decimated by overharvesting, but thanks to decades of protection, they are making a comeback. Both the honu and honu ʻea are protected under the federal Endangered Species Act and state laws in Hawaiʻi, making it illegal to harm, harass, or disrupt them in any way.

The Golden Rules of Ethical Turtle Viewing

Observing wildlife in its natural habitat is a privilege. To ensure the safety of both you and the turtles, please follow these guidelines from NOAA Fisheries and the State of Hawaiʻi Division of Aquatic Resources. Remember, you are a guest in their home.

Keep Your Distance: This is the most important rule. Always stay at least 10 feet (3 meters) away from sea turtles, whether they are in the water or on the sand. This is a legal requirement. An easy way to measure is to imagine two adult-sized snorkelers lying head-to-toe between you and the turtle.
Never Touch, Chase, or Feed: Touching a turtle can transfer bacteria and diseases (in both directions) and causes them stress. Chasing them in the water disrupts their natural feeding and resting patterns. Feeding them is harmful and illegal.
Don't Block Their Path: Turtles basking on the beach need a clear path back to the ocean. Never stand between a turtle and the water. Give them plenty of space to move freely.
Use Reef-Safe Sunscreen: Standard sunscreens contain oxybenzone and octinoxate, chemicals that are incredibly harmful to coral reefs and marine life, including the turtles' food sources. Choose mineral-based sunscreens with zinc oxide or titanium dioxide.
No Flash Photography: Sudden, bright flashes can startle and disorient turtles, especially at night or in low-light conditions. Use natural light and turn off your flash.
Observe Quietly: Approach basking areas quietly and avoid making loud noises. Use the zoom lens on your camera or phone to get a closer look without physically approaching.

Best Turtle Beaches on the Kona & Kohala Coasts

The dry, sunny western side of the Big Island is turtle paradise. Clear waters and calm coves make it the most reliable area for sightings.

Punaluʻu Black Sand Beach

Located in the southern Kaʻū district, Punaluʻu is arguably the most famous “turtle beach” in all of Hawaiʻi. The jet-black sand, created by lava flowing into the ocean, absorbs sunlight and creates the perfect warm spot for honu to haul out and bask (pē ʻana i ka lā, or 'basking in the sun'). It’s not uncommon to see several turtles resting here at any given time, especially in the afternoon. Be aware: the surf here can be rough and is not recommended for novice swimmers or snorkelers.

Kahaluʻu Beach Park

Just south of Kailua-Kona, Kahaluʻu is one of the island's most reliable and accessible snorkeling spots for seeing turtles. The shallow, protected bay is teeming with fish and honu that come to graze on the abundant algae. Because it’s so popular, it’s especially important to be mindful of your space and not crowd the turtles you encounter while snorkeling. Look for the on-site educators from The Kohala Center's Reef-Teach program, who can provide great information.

Kīholo Bay

For a more adventurous outing, Kīholo Bay on the South Kohala Coast is a stunning location. It requires a bit of a walk from the highway or access via a rough unpaved road. The reward is a beautiful bay with a mix of black sand, lava rock, and a large, brackish water pool called Wainānāliʻi Pond where turtles love to congregate. You can often see dozens of them popping their heads up for air. It feels like a prehistoric, untouched piece of Hawaiʻi.

ʻAnaehoʻomalu Bay ("A-Bay")

Located in the Waikoloa Beach Resort area, A-Bay is a long, curving white-sand beach with ancient fishponds behind it. While it’s a popular spot for swimming and paddleboarding, turtles are frequently seen resting on the sand, particularly on the southern end of the beach near the lava rock outcroppings. The easy access and calm waters make it a great, family-friendly option.

More Spots for Turtle Sightings

Hungry for more? These locations also offer frequent turtle encounters, often with fewer crowds.

Hōnaunau Bay (Two Step)

Next door to the Puʻuhonua o Hōnaunau National Historical Park, Hōnaunau Bay (known as "Two Step" for its natural lava rock entry point) is a world-class snorkeling and diving destination. There isn't a sandy beach here, but the exceptionally clear water and healthy reef provide a window into an aquatic world where turtles, dolphins, and endless schools of fish are common sights.

Richardson Ocean Park (Hilo)

On the east side of the island, your best bet for turtle viewing is Richardson Ocean Park in Hilo. This collection of protected coves with black sand and calm pools is a popular feeding ground for honu. While basking is less common here than on the Kona side, you have a very high chance of seeing them while swimming or snorkeling in the protected waters.

Guided Snorkel Tours

Many boat tours, particularly those that visit the protected Kealakekua Bay, offer fantastic opportunities to snorkel with turtles in open water. Opting for a tour with a reputable operator ensures you are in the hands of professionals who prioritize marine life safety. Many of the partners recommended by High End Hawaii run small-group tours that focus on respectful wildlife encounters and education.

When to See Turtles

You can see sea turtles on the Big Island year-round! They are resident animals and do not migrate away from the islands for feeding.

For Basking: The best time to see turtles resting on the beach is often in the afternoon, from about 1 p.m. until sunset, when they come ashore to digest and regulate their body temperature after a morning of foraging.
For Snorkeling: Mid-day, when the sun is directly overhead, provides the best visibility for spotting turtles in the water.

Remember that these are wild animals on their own schedule. While these locations offer a high probability of a sighting, nothing is ever guaranteed. The thrill is in the search and the privilege of sharing a moment with these incredible creatures in their natural home.

Frequently asked questions

Is it guaranteed I'll see turtles at these beaches?

While these locations offer a very high chance of seeing turtles, they are wild animals, so sightings are never guaranteed. Visiting in the afternoon often increases your chances of seeing them basking on the sand. Patience and respect are key.

What is the fine for touching a sea turtle in Hawaiʻi?

Touching, harassing, or disturbing sea turtles is illegal under state and federal law. Fines can be substantial, running into the thousands of dollars, and can even include jail time. It's crucial to respect the law and give them their space.

Why do sea turtles come onto the beach?

Hawaiian green sea turtles are unique in their behavior of 'basking,' or coming ashore to rest in the sun. They do this to regulate their body temperature, conserve energy for foraging, and possibly avoid predators like tiger sharks. A basking turtle is not sick or stranded; it is simply resting.

What's the difference between a honu and a honuʻea?

The honu is the Hawaiian green sea turtle, which is larger with a rounded head and a primarily herbivorous diet of algae. The honuʻea is the much rarer hawksbill sea turtle, which is smaller with a distinctive, sharp, bird-like beak used to eat sponges from the reef.

Is it safe to swim or snorkel with sea turtles?

Yes, it's generally safe as long as you maintain a respectful distance of at least 10 feet. Do not chase them, block their path, or attempt to touch them. Observe them calmly and let them go about their business. They are gentle creatures and pose no threat if left alone.

What do I do if I see a sick, injured, or stranded turtle?

If you see a turtle that appears to be in distress, injured, or entangled, do not intervene yourself. Keep a safe distance and report it immediately to the NOAA Marine Wildlife Hotline at (888) 256-9840. Note the exact location and a description of the animal.
