Why dive here
With 213+ marine species recorded in the area - including barracuda, dolphins, eagle rays, nurse sharks and sea turtles - Long Caye offers some of Lighthouse Reef's richest diving. Water ranges 27-30°C, warmest August, September, October.
Long Caye, out in the southern reaches of Lighthouse Reef, offers a relaxed kind of wall diving we really enjoy. Along the west coast, you’ll find expansive coral gardens topping a wall that just keeps going down. It’s a comfortable depth, around 10 meters, so you can take your time scanning for nurse sharks tucked under ledges or graceful eagle rays gliding past in the blue. This is a site that suits divers who appreciate a slow drift along a healthy reef, where the macro life often reveals itself after a few minutes of quiet observation.
