Half Moon Wall - Roatán

Little Bight is a delightful little spot, especially if you’re into the smaller stuff. We love it for its gentle slope, transitioning from a shallow sandy patch near shore to a more reef-fringed edge at around 17 metres. It's an easy dive, perfect for photographers wanting to take their time or for divers who just want to drift and look. Forget the big pelagics here; Little Bight is about slowing down. We’ve spent whole dives just combing the sand for garden eels, watching them retract in unison as you approach. Keep an eye out for those tricky little pygmy filefish, they blend in beautifully. We’ve also had some luck spotting rigid venus sea slugs creeping along the sand and even spaghetti eels poking their heads out of the substrate. The bluestriped grunts often hang out in schools near the coral heads, creating a lovely contrast against the sand. We'd suggest going in the morning; the light plays beautifully on the sandy bottom then, making it easier to spot the smaller creatures. Visibility here tends to be reliable, averaging around 17 metres, which means even on an 'average' day, you'll have good viewing.
