Site details

Cathedral Reef off Ambergris Caye is named for its tall, light-filled coral canyons and archways that evoke a cathedral interior. Sand-floored gullies between 15 and 30m wind past sponge-covered walls where turtles, rays and reef sharks pass. It is a scenic intermediate spur-and-groove dive popular on San Pedro boat trips.
