"Meet Humuhumunukunukuapuaa The most colorful of all the state fishes also has the most spectacular name: Hawaii’s Humuhumunukunukuapuaa. While the name is unusual, the Humuhumu (for short) is fairly easy to spot at any good snorkeling beach in the Hawaiian Islands. The one pictured was spotted in the protected Keauhou Bay on the Big Island where the water is clear and fish abound. It is also a great place to spot green sea turtles munching on algae in the shallow pools near the shore."

This bay has the most "electric blue" water that you have probably ever seen. There is also a small beach, a pier that is very popular with local anglers, and an interesting little historical park. With free public parking and a restroom, it's a beautiful spot to check out for 20-30 minutes. The fisherman are quite friendly if you feel like talking story!

A beautiful bay, The Royal Hawaiians from the past lived here and there is lots of historical information. Most of the snorkel and boat trips leave from here.

This is not a Sandy, lay around beach. This beach has amazing, outstanding snorkeling and is great for beginner to novice surfers as well. There is a picnic area and a clean bathroom and shower place. We loved our time here!

Love swimming here, jumping off the Dock and getting out at the boat ramp. No facilities and some private property signs but the area around the water is for public use. Absolutely beautiful area.

Cool place can see fish from the docks and mongooses running around. Go early if you do not want to walk as parking is limited and fills up quickly. A few tour boats leave fro. Here which can end up getting busy and having to park 1/2 mile away and walking in.

One of my pledges this year is to complete more reviews of dive shops & sites. Keauhou Bay is one of two sites in Kona for night manta dives, I've done one there. But some Kona dive friends have introduced me to much better dive opportunities there during the day time. Located on Ehukai St near the old location of the Sheraton, now an Outrigger hotel, there is a cross walk that leads out to a concrete path. At the end of the path, there is a jump off point into the water, and rock pathway out of the water. Once in the water (don't forget your dive flag), follow the reef out about 100 yards. This is an active boat channel, so if you surface swim out partways, stay on the side closest to the hotel. There will be a slow incline, then it will rapidly descend to the bottom. Stay along that ledge going out until you see a concrete pylon on its side. That is the area the becomes the "campfire" on the night manta dive, where all the lights are set to attract the mantas. During the day, that area is a manta cleaning station, where they slowly move around to allow fish to come and clean them by eating algae and other things that irritate their skin. As fun as it is to see the mantas rushing around at night trying to eat plankton as fast as they can, there is a poetic beauty to seeing them moving slowly during the day. For 2 out of the 3 dives I've done there, we've also been lucky enough to see sub-adults who are a lot more curious than most and got came very close to us! The reef there is pretty dead there, so there pretty much there isn't much else to see there. But to see the mantas gracefully moving around the cleaning station, wow! Repeat and recommend!

It is almost always crowded at Keauhou Bay especially around sunset and night and that is because of all the night snorkeling tours that go out to view the manta rays! There is roadside parking on Kamehameha II Road but that fills up very quickly as expected. Anyways, the bay itself is beautiful to check out and it is protected from rough waves and currents. But it's mostly full of commercial snorkeling companies and resorts, so there isn't a whole lot to do outside of that other than standing or sitting and enjoying the views.

Keauhou Bay was the meeting point for our snorkel sail aboard Fair Wind's Fair Wind II boat. PARKING: Because we were going on tour, we were allowed to park in their dedicated gravel lot just off of Kamehameha II Road. All others can park along the roadside, which wasn't crowded at all, even on a Sunday. THE BAY: The bay sports a tiny black sand beach which is well protected from waves, restrooms, and is home to a canoe club, dock, moored boats, Fair Wind Adventures, boat ramp, and a restaurant called Akule Supply. Other than a local family having a party on the grass, and a few people fishing, the bay in general seems like a low key area. It isn't the prettiest of beaches but the surrounding scenery is beautiful. OVERALL: More commercial than leisure.

This wasn't a destination for me, per se, but a stop on my morning walk from the resort. It's about a 3 mile round trip from Holua property and a nice stop for the halfway point of my walk. It seems to serve as a staging area for water excursions and had a landing area with many folks heading out to start their day with various tour groups. Other than a small grassy area, a tiny beach which and a wall you can sit on, there is it not much to do other than enjoy the views. If you're staying in the area, it's a nice place to talk a walk to.

Love this bay. Took off from this bay to 3 of my open sea adventures. Very friendly folks here at the bay. You have to come here if you are on this side of the island.

I came here on a Thursday night -7pm- to go on a manta ray night dive with some locals we met with. We traveled with the canoe club (hut! Ho!) out near the lights of the Sheraton and jumped into the water with our snorkels and flashlights. Almost immediately, we spotted a manta ray beneath us. We hovered around, bobbing on the surface for another 10 minutes with our underwater flashlights, and then the mantas got hungry. GIANT 14 ft- wing span mantas swimming toward you: they've got a black top, and a huge, gaping mouth, wide open. They seem to be playing chicken with you: who's going to move? Not I. I couldn't move, unless I want to kick the ray, damaging their fragile skin. I stayed afloat, breathing DEEP, NERVOUS breaths, the manta ray still staying on track coming closer and closer to my face. At the last minute, he does a flip, leaving us belly to belly, almost grazing my entire body with his white underside. His white underside has little black spots, as my boyfriend & I call them, "puppy spots" like a dalmation. He continues to do 3-4 flips beneath me until he swims off, only to return for more flips beneath our flashlights. We had 3 or so mantas grazing beneath our flashlights, enjoying the plankton photosynthesizing in our flashlights' beams. The water was calm, the moon was non-existent; it was only the 12 of us, our underwater flashlights, and the mantas. Until there were jellyfish-prickling our skin. It was a truly amazing experience that I will never forget for the rest of my life.
