Keyhole

Keyhole is a wall dive off Roatan in the Bay Islands of Honduras, part of the fringing reef system that runs along the island's coastline before dropping sharply into deep water. The site is reached by short boat trips from operators based on the island. Keyhole reaches a maximum depth of around 100 metres and is rated a technical dive, well beyond the shallower reef profiles found along much of Roatan's wall. Divers have reported a range of reef fish on the site, including Atlantic blue tang, sergeant majors, blueheaded wrasse, four-eyed butterflyfish, longsnout seahorses, queen angelfish, and both stoplight and yellowtail parrotfish.
