Guacamaya Island - Caribbean Coast

Lighthouse Reef is a site we keep coming back to, mainly for the nurse sharks. This isn't a deep dive, maxing out at 20 meters, but it’s an exposed patch reef, so surface conditions can be a bit bouncy. Don't let that deter you though, because below the waves, it's a completely different story. We love finning through the overhangs and around the large rocks here, always with an eye out for those big nurse sharks. They tend to chill in the shadows, and we've seen some truly huge ones, easily three meters long. If you're lucky enough to dive it mid-year, you might even spot some pregnant females, which is a rare treat. Beyond the sharks, there are some impressive sea fans swaying in the gentle surge, and we often spot barracuda patrolling the reef edge. Keep an eye out for the smaller stuff too, like the Harlequin Bass darting between the corals and the Blackfin Blennies peeking out from their holes. It's a relaxed dive, good for photographers or anyone who enjoys a bit of exploration with a strong chance of a memorable encounter.
