    StandoutExceptional marine biodiversity

    Big Bight in Roatán is one of those spots we always recommend for divers who like to take things slow and really explore the nooks and crannies. It’s a channel dive, essentially, with walls of coral and rock that feel like an underwater canyon. We love to drift through, letting the gentle current guide us over the sandy patches fringed with turtlegrass. Keep an eye out for the small stuff here, the goby peeking out of its burrow, maybe a Blackberry Drupe clinging to a rock. The maximum depth of 20m makes it comfortable for divers of all experience levels, and honestly, you don't need to go deep to appreciate Big Bight. Our favourite time to dive it is in the late afternoon, when the light shifts and paints the coral in deeper hues. You’ll often spot a Green Moray Eel peeking from a crevice or a big Blue Parrotfish munching on the reef. It’s a great site for seeing how many different species of cone snails you can spot – they’re everywhere if you look closely.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
