Quick answer: The most reliable place to see honu near Kealakekua and Kailua-Kona is Kahaluʻu Beach Park at Keauhou, where green sea turtles come in to graze on the reef most mornings, and Honokōhau Beach in Kaloko-Honokōhau National Historical Park, where they haul out onto the sand to sleep. Stay at least ten feet away in the water and twenty on land, never touch one, and do not drive to Punaluʻu for turtles right now, because the park has been closed since the county lease ended in August 2026.
Almost every list of where to see sea turtles on the Big Island sends you to the same two places and skips the part that matters, which is how to behave once you find one. We live ten minutes up the hill from Kealakekua Bay and see honu most weeks, and what we end up telling guests is that a turtle asleep on the sand is not a photo opportunity waiting for somebody to improve it.
So this is both halves. Where they reliably are on this coast, what has changed this year, and the rules, which are stricter than most visitors expect.
The rule that matters more than the map
NOAA asks you to stay at least ten feet away from a sea turtle, in the water and on land. The national park at Honokōhau asks for twenty. Give them the bigger number and you will never have to think about it again. The NOAA marine life viewing guidelines are worth two minutes before you get in the water anywhere in Hawaii.
Harassing a sea turtle is illegal under federal and Hawaii state law, and harassment is a wider word than people assume. It is not only touching. It covers following one, cornering it, standing between it and the ocean, and crowding it until it gives up and moves.
The practical version is one sentence. If the turtle changes what it is doing because of you, you are too close. No touching, no riding, no feeding, no flash, no drone overhead. If one swims toward you while you are floating, hold still and let it pass.
Kahaluʻu Beach Park, the one that actually works
Kahaluʻu is at Keauhou, five miles south of Kailua-Kona, ten minutes from our condo in town and about twenty five from Kealakekua. The reef starts almost at the sand, and the honu come into the shallows to graze on the algae growing on the rock. If you have one morning and want to see a turtle, this is where we send you.
The Kohala Center has ReefTeach volunteers on the beach every day the park is open, 8:30 in the morning until 3 in the afternoon. Check in with one before you get in. They will tell you where the turtles were that morning, which is information no website has, and their orange buoys mark where you must not stand. They ask for mineral sunscreen only, zinc oxide or titanium dioxide, the same thing we say in our guide to snorkel gear in Kona. What the ReefTeach program asks of visitors is on their page.
The honest part: it gets busy and parking is the whole difficulty. Make it a before nine plan and it is a different beach. It is also the most forgiving snorkeling on this coast, which is why it is top of our list of the best beaches for kids on the Big Island. The loaner bins are stocked for adult faces, so bring a mask for a child. More of what the water here offers is on our Ocean Activities page.
Honokōhau Beach, where they come out of the water
North of Kailua-Kona, past the boat harbor, is Kaloko-Honokōhau National Historical Park. Park at the harbor end or the main lot and walk in over the lava. This is the most reliable place on the Kona coast to see honu basking, which means asleep on the sand above the waterline rather than swimming past you.
The park asks for twenty feet rather than ten, and says plainly that a turtle which goes back in early has not finished resting. It is their beach and their number, so use it. The park page on sea turtles is clear about the rest.
Worth knowing before you treat it as a turtle stop: this is a real place with Hawaiian fishponds, a shoreline fishtrap and a visitor center, not a beach with turtles at it. Give it a proper hour. There is no shade, so go early or late. Entry is free.
Two Step, Kealakekua Bay and the South Kona water
Hōnaunau Bay, which everybody calls Two Step, has the clearest water in South Kona and turtles pass through it regularly. Regularly is not the same as reliably, so go for the water and treat a turtle as the bonus it is. Parking is the difficulty here too, so go early, and walk next door afterward to Puʻuhonua o Hōnaunau, which is worth a proper couple of hours.
Kealakekua Bay itself is a protected marine area with a resident pod of spinner dolphins and the healthiest reef within reach of the house. Turtles turn up there too. Our guide to snorkeling at Kealakekua Bay explains how to get to the good water without trying the hike, which we talk people out of most weeks. The other stops along this coast are on our South Kona page.
Not to be confused with any of this: the manta ray night snorkel is a different animal entirely, an evening boat trip rather than a shore entry, and the one ocean thing we recommend to nearly everybody.
Punaluʻu, and why we are telling you to wait
Punaluʻu, the black sand beach down in Kaʻu, is the photo everybody has seen: green turtles asleep on black sand with palms behind them. It is the single most recommended turtle spot on the island and every guide still lists it.
Here is what those guides do not say. Hawaii County had leased the land for decades, the lease ended on 29 August 2026, and the park closed. On 14 October 2026 the county announced a tentative deal to buy the parcel and keep it open permanently, which is good news, but the purchase could take months. Until it goes through, the parking, restrooms and pavilions are not operating.
It is more than two hours each way from Kealakekua. Do not spend a day of a seven day trip on it without checking the Hawaii County parks notices the week you travel, and do not trust this page either. We will update it when the beach reopens. If you are going down that end of the island anyway, our guide to the green sand beach and South Point covers the same drive and is honest about what that day costs you.
Kiholo Bay, if you are already up the coast
Kiholo is a state park reserve up the Kohala Coast, and turtles are often in the brackish lagoon there. It is a rough access road and a walk along the shore, and the gate hours change, so check the state parks notices rather than turning up. Treat it as a half day of its own, not a stop on the way to something else. If you are heading that way for the sand instead, our list of the best beaches near Kona is the better starting point.
What a basking turtle is, and what to do about it
Hawaii green turtles are the only population in the world that routinely hauls out onto land to rest in the sun. A turtle lying still on the sand with sand on its shell is not sick, not stranded and not dying. It is asleep.
So do not pour water on it to help, and do not push it back toward the ocean. Do not form a ring of people around it either, which is the most common thing that goes wrong, because everyone is individually ten feet away and the turtle is still surrounded. Back off, give it twenty feet, and let it sleep. If one is visibly injured or tangled in fishing line, that is the time to call it in, and the park or the lifeguards will know the number.
An honest note about the photo on this post. That is a basking honu, photographed at Laniakea on Oʻahu, where basking is far more common than it is here. On the Kona side you are more likely to meet one in the water than asleep on sand, and Honokōhau is the exception.
There is no turtle tour, and that is a good thing
Nobody can sell you a guaranteed turtle encounter. Anybody implying otherwise is either overselling an ordinary snorkel trip or doing something they should not. There is no feeding program, no touch tank and no swim with turtles operation in Hawaii, because all three would be illegal. A turtle on a boat trip is a bonus, not a product.
Which means the free version is also the best version. Kahaluʻu costs nothing but a parking space and getting up early, and Honokōhau costs nothing at all. Both are near the top of our list of things to do in Kona.
How to actually find one
Go in the morning, before the wind comes up and the water gets stirred. The first sign is almost always a head breaking the surface for a breath, held there a second or two, then gone. Watch for that, then look down along the rock line where the algae grows, because that is what they came in for.
Then float. Do not swim at it. Move parallel rather than toward it, and stay still when it is feeding. Fifteen patient minutes in one spot beats an hour of crossing the bay, which is the mistake most people make. Flat water helps more than anything else, so pick your day: our notes on the best time to visit the Big Island cover which months give you the calmest water, and in winter you will be watching for whales from the same beach.
Questions we get asked
What is the best place to see sea turtles on the Big Island? Kahaluʻu Beach Park at Keauhou for turtles in the water, most mornings, with volunteers there to point you the right way. Honokōhau Beach in Kaloko-Honokōhau National Historical Park for turtles basking on sand. Both are free and both are within half an hour of Kailua-Kona.
Is Punaluʻu Black Sand Beach open right now? As of the middle of October 2026, no. The county lease ended on 29 August 2026 and the park closed, and although a purchase deal was announced on 14 October it has not completed. Check the Hawaii County parks notices the week you travel before committing a day to the drive.
How close can you get to a sea turtle in Hawaii? Ten feet is the figure NOAA asks for, in the water and on land. Kaloko-Honokōhau asks for twenty. Harassment is illegal under both federal and state law, and it includes following, cornering and blocking a turtle from the water, not just touching it.
Do you need a tour to see turtles in Kona? No, and there is no such thing as a turtle tour here. Shore snorkeling at Kahaluʻu or a walk at Honokōhau will do it. Boat trips to Kealakekua Bay are worth booking for the reef and the dolphins, and a turtle on one is luck rather than the itinerary.
Are there turtles at Kealakekua Bay? Yes, though it is better known for its spinner dolphins and its reef. Two Step at Hōnaunau, fifteen minutes further south, is the more dependable turtle water in South Kona.
Where to stay for the water
All of this works from one house. Casa Grateful is our one bedroom in Kealakekua, the one couples take, ten minutes up the hill from Kealakekua Bay and twenty from Two Step. Casa Gratitude is the one for families and groups, also in Kealakekua, with two bedrooms and two bathrooms and a third bedroom for children on request. Casa Aloha is our condo in Kailua-Kona, ten minutes from Kahaluʻu, walkable to dinner in town, with a pool that sits right on the ocean.
Casa Grateful and Casa Aloha come with snorkel gear, a cooler, beach chairs and an umbrella. Casa Gratitude does not, so rent or bring your own if you are staying there. Check in is 4pm and check out is 10am, with earlier or later available for an additional fee if the calendar allows, and the rest of the house rules are on our FAQ page.
Have a look at all three homes, see how a week fits together in our seven day Big Island itinerary, read a bit about who we are, and if you want a recommendation for your particular week, just ask. More local guides live on our blog, and the town side of things is on our Kailua-Kona page.
