The world's second deepest underwater sinkhole — a 202-meter deep blue hole on Long Island, Bahamas, used for free diving world records and surrounded by one of the finest cove beaches in the islands.
Why It’s Worth Your Time
Dean's Blue Hole on Long Island is the world's second deepest known marine blue hole, plunging to 202 meters (663 feet). The surface opening is a nearly perfect circle of dark blue water set within a stunning turquoise cove — it's visually extraordinary even from the beach. The site has been used repeatedly for world freediving record attempts; the water clarity and depth make it one of the great technical dive sites on Earth. For non-divers it's simply one of the finest beaches in the Bahamas. Long Island requires a flight but rewards those who make the effort — very few crowds.

- World's second deepest underwater sinkhole — 202 meters
