"Dean’s Blue Hole Nestled inside a protected cove on the coast of Long Island, Dean’s Blue Hole is an unusual natural wonder. From the shore, it looks like a round patch of blue water surrounded by turquoise green. That’s the result of a massive sinkhole that collapsed near the shore, creating a natural tunnel that drops to more than 660 feet deep, making it the deepest blue hole in the world. The site is commonly visited by scuba divers and free-divers who explore the vertical cavern walls. It’s also a great place for swimmers, and because it’s protected within the cove thereare no currents or waves to worry about."

Great spot to stop in with the whole family. Nice beach and shallow area for those that don't want to venture into the deeper water. Great snorkling around the perimeter of the hole with fish and other marine life. Platform is set up in the middle with lines going down for the competitons. You can climb up and jump off the rocks into the water. There is a small jumping spot and a bigger one for those dare devils.

Deans Hole is a fantastic spot for both a quick exploration and an entire day of beach fun. Whether you’re stopping by briefly to soak in the scenery or spending your day snorkeling and enjoying the coastal vibes, this place offers something for everyone. I really enjoyed my time there, and I highly recommend making a visit. The beautiful beach and clear waters provide a perfect backdrop for both adventure and relaxation.

So we came here in the morning had the whole place to ourselves, pretty amazing experince didn't expect the fish to come right up to you, the water was so clear. Also climbs the backside to see it from above, just an all around cool spot.

Well worth the visit. Known for freediving but was a nice snorkel spot. Accessible by beach. Would be good for scuba diving as well.

Spectacular place to visit. Highly recommend. Plan your visit as you’ll need water, towel, snacks etc. Nothing around, which is exactly how we liked it. Stunning contrast between the crashing waves around the corner and the peaceful bay and blue hole. Mesmerizing!

Beautiful scenery. Absolutely astonishing. It's nice to snorkel and on a sunny day you can see pretty far into the hole. Hold your breath and see how far you can dive. Nice to see the fish swimming around. There is also a dive deck for scuba diving.

Great place. I decided not to freedive all the way down since I just had lunch so I can't really tell how if its good at the bottom.

Great spot for a fun exploration. There are some amazing shallow areas. Beautiful clear water. There weren't a lot of people. Very relaxing fun spot. Definitely not overcrowded. Worth the time. Highly recommend.
