Sea turtles at Napili Bay: where, when, and how close
Honu are regulars here. They come in to graze the algae on the rock at both points, and on a calm morning you can watch one work the shallows for twenty minutes. Ten feet is the distance. That part is not optional.

Green sea turtles — honu — are the reason a lot of people end up at Napili Bay rather than the beach outside their own condo. They are here for the algae growing on the lava, which is why they are almost always at the edges of the crescent and almost never out in the sandy middle.
You are not looking for turtles in open water. You are looking along the rock, in three to eight feet, where the reef meets the shallows. Swim the shoreline toward either point with your face down and let them appear.
Calm water beats clever timing.
People want a magic hour. The honest version: early morning and late afternoon are your best windows, but what actually determines your odds is how calm and clear the water is. A churned-up bay hides everything regardless of what time you show up.
So the early-morning advice is not really about turtle behaviour. It is about the fact that the bay is glassy before the trades build, visibility is at its best, and there are fewer people in the water pushing them off the rocks. Same reason the snorkelling is better then.
If you get a flat, clear, quiet morning at Napili Bay and you swim the shoreline toward a point, your odds are good. If you get a windy afternoon in February, they are not — and no amount of patience changes that.
How close you are allowed to get.
Hawaii’s standard is ten feet — about three metres — in the water and on the sand. Green sea turtles are federally protected, and the guidance is enforced. Ten feet is closer than people expect and further than most people behave.
What that means in practice: do not touch, do not chase, do not feed, do not ride, do not reach out, and do not position yourself between a turtle and the open water or between a turtle and the surface. They breathe air. Blocking the way up is not a neutral act.
If one swims toward you, hold still and let it pass. The rule governs your behaviour, not the turtle’s — you are not breaking it by being approached, only by pursuing. Same on the sand: a honu hauled out to rest is resting. Give it the distance and take the photo from where you are.

Honokeana Cove is two minutes south.
Napili Bay is reliable for turtles. Honokeana Cove, just down the coast, is famous for them — smaller, rockier, less sand and more structure, with honu often visible from the rocks without getting in at all.
It is a different kind of visit: no real beach, harder entry, and it sits in front of a residential condo community, so go quietly and park considerately. Kapalua Bay, a few minutes north, is the third of the local turtle spots and the easiest of the three to park at.
All three are covered in the nearby beaches guide.
FAQ
Turtle questions
Are there sea turtles at Napili Bay?
Yes. Green sea turtles — honu — are seen regularly at Napili Bay, most often along the rocky edges at the north and south points where they graze on algae.
What time of day is best to see turtles at Napili Bay?
Early morning, when the water is calm and clear and the crowds are thin, and again late in the afternoon. Calm water matters more than the clock: when the bay is churned up you will not see much of anything.
How close can you get to a sea turtle in Hawaii?
Hawaii asks you to stay at least 10 feet away from honu, in the water and on the sand. Never touch, chase, feed, ride, or block the path of a turtle — green sea turtles are federally protected.
What do I do if a turtle swims toward me?
Hold still and let it pass. The 10-foot rule is about your behavior, not the turtle’s. Do not swim after it, and do not reposition yourself to stay close.
Where else can you see turtles near Napili?
Honokeana Cove, just south of Napili Bay, is a well-known turtle spot — smaller and rockier, with turtles often visible right off the rocks. Kapalua Bay to the north is another reliable one.
