Dean's Blue Hole

Dean's Blue Hole is a marine sinkhole on Long Island near Clarence Town and is the second-deepest known blue hole in the world, plunging 202 meters straight down from a shallow sandy beach entry. The hole is set within a small protected bay that allows shore entry into completely sheltered water, with the rim sitting in just a few meters of depth before the bottom drops sharply away. For recreational divers the site offers a dramatic and easy descent: kick out from the beach, fin over the lip, and watch the wall sheer into darkness. The upper walls in 10 to 25 meters host small tropical fish, sergeant majors, and the occasional barracuda or stingray. Below that, depth and overhead-environment-style conditions take over. The site is a global freediving mecca and has hosted multiple world-record attempts, including those by William Trubridge and Alexey Molchanov. Visibility is generally good and conditions are calm thanks to the protected setting.
