    StandoutExceptional marine biodiversity

    Northern Tip offers some good drift diving, especially on the west side. We’ve found leopard sharks resting on the sandy bottom here, and the granite boulders provide shelter for a lot of smaller reef fish. It’s a solid choice if you're looking for a relaxed dive with consistent conditions.
