CharacterReef dive

StandoutExceptional marine biodiversity

Seal Cay is one of those places on the Corn Islands that just feels right, a solid little dive. It’s an islet, really, with a decent spread of coral that offers a reliable fix of Caribbean reef action. We've seen a good mix of species here – the usual suspects like grunts, snapper, and the occasional inquisitive nurse shark gliding by. Visibility can be excellent, especially on a calm morning, letting you take your time exploring the nooks and crannies. It’s a great spot for a relaxed dive, suitable for most skill levels, and often feels like you have the place to yourself, which is always a bonus.
