Lost City - Inner Islands

Lost City, off the Inner Islands, presents a landscape of granite boulders scattered across the seabed, creating a maze of swim-throughs and small caverns. It’s a site that rewards a slow pace, allowing you to peek into every crevice for resident moray eels or camouflaged scorpionfish. We find it’s best for divers who enjoy exploring structure rather than seeking out pelagics, though schools of snapper often cruise by. Visibility here can vary, so pick a calm day for the clearest views.
