The Blue Hole
Why dive here
With 210+ marine species recorded in the area - including barracuda, dolphins, eagle rays, nurse sharks and sea turtles - The Blue Hole offers some of Utila's richest cenote diving. Water ranges 27-31°C, warmest June, August, September.
Utila’s Blue Hole, not to be confused with its famous Belizean cousin, offers a different kind of drop. We're talking about a volcanic swim-through here, not a giant sinkhole. The entry can be a bit tricky, often through a surge channel, so keep an eye on conditions. Once you’re in, you’ll navigate through some striking rock formations. It's a tighter squeeze than some might expect, leading to a small cavern where light filters down from above. You won't find large pelagics here, but it's a unique geological dive for those who appreciate the shape of the reef itself. Best for experienced divers comfortable with overhead environments and minor current.
