Stargate

Stargate on Andros Island is one of the most famous blue holes in the world, named for its perfectly geometric underwater opening that resembles a portal to another dimension. This advanced site features a large circular opening in the reef at about 15 meters that drops into an enormous cavern system below. Ancient stalactites frame the entrance, and the crystal-clear water allows light to penetrate deep into the void. Schools of silversides create living curtains of light during summer months. The site's otherworldly beauty has made it a bucket-list dive for adventurous divers worldwide.
