(4.4/5 based on 11,000+ reviews on the web)
Famous for its sheltered inlet of calm and clear turquoise water, Hanauma Bay Nature Preserve protects about 400 different species of fish and attracts amateur and professional snorkelers from around the world. The bay is also a nursery for green sea turtles, which you may see nesting as you walk or swim along the coastline. You can rent diving equipment if you don't bring your own and spend a day searching for parrotfish and coral. The preserve's regulations prohibit touching or walking on the coral heads, which often resemble large rocks on the ocean's floor. Keep in mind that touching or brushing up against coral or marine rocks may also result in serious wounds.

  • Being a rainy day I was worried for some fish species was going deep in the rich and so enjoyable was the entry fee to receive a snorkel points I'm not puffy

  • Amazing snorkling for all levels. You can see beautiful, tropical fish everywhere. Go early because it does get crowded. 
  • My teenage children said numerous times "this is the best thing we've done all trip!!!" Snorkel out to the edges and go out away from the shore. The colours of the reef are best there. Way more school...  more »

  • This bay is very beautiful but the quality of the coral is not. With all the tourists that flock here everyday it's open ( closed on Tuesday) the coral has taken a hammering and it's not as vibrant or alive as it should be. Upon arrival you watch a video explaining how to protect the coral. This does not stop tourists from standing all over the coral, which is not allowed! It's so frustrating to see such lack of care for the environment. Granted there is still fish to spot, it's sad to see the coral so grey and life less. Pro tip : arrive early, between 6-730am if you want a car park. Also the water has better clarity in the morning. Pro tip 2 : bring an underwater camera. The fish eyeball you in this bay! They come right up to your mask and are more inquisitive than timid. This is also a great bay for beginners and kids with lots of sandy entry points and water is shallow with coral close to the beach.
  • This is the number one tourist attraction in Hawaii and rightfully so, it's a beautiful place to go snorkeling. Just plan ahead. Closed on Tuesdays. Parking may get full sometimes, so get there early. Parking will cost you $1 (free if you're cycling, using a moped or walking in). Entrance fee is $7.50 for tourists and free for Kamaaina (locals) and military. Oh yeah, you have to watch a video as well. Other than that, snorkeling here is awesome. I go at least 1-2 times a month.
  • This is without a doubt the most beautiful water I have ever seen. When you walk along the path down to the bay you are greeted with an overhead view of the reef below the water which beckons you to come closer and experience what Hanauma Bay has to offer. All first time visitors must go through a briefing before being allowed to enter the bay. This is to protect the environment as well as educate on what you are about to experience. Spend the day snorkeling or read a book under a large palm tree. As with all Oahu beaches, there are families and tourists everywhere but the serenity of this natural volcano made bay brings you in and massages you soul with relaxing sounds, eye-watering views, and warm sensual waters. A must see when vacationing on the island.
  • It's really nice that they've tried to preserve this. The informational video that they play before you go down to the bay was nice. The lady presenting it was very friendly and accommodating to the handicap or pregnant women who needed seating. The walk down to the bay was nice you could either walk or pay for a trolley down. The snorkeling part was fun as well we saw many fish and corral. You could definitely tell that the ecosystem has changed from what it used to be, now that it's taken care of properly hopefully it starts to thrive again like it once did.
  • A wonderful place to snorkel on Oahu especially if you are with a family. There are many fish and occasionally sea turtles. There is an entrance fee to get into the park however this fee allows for crew to keep the park nice and clean for your visit. There is a good size parking lot which usually fills up midday. The park is closed on Tuesdays. So plan your visit accordingly.
