    Narwall is a solid wall dive in the Florida Keys. We've found it’s best explored as a drift, letting the current carry you along the reef face. Look out for the usual Keys suspects here – snapper, grouper, and schooling grunts hiding in the overhangs. It's a good choice for divers comfortable with current, offering a relaxed but engaging experience.
