Boca Chita Key is part of the Biscayne Bay National Park, and a small marina/harbor is maintined here by the Park Service. I’ve always found the depths rather shallow here, but note that Captain Pascal below says 5 feet can be maintained. Also, and this is not the first posting we’ve had here on the Net about this subject, Boca Chita Key is definitely NOT pet friendly.

Cruising News: I see the note about no dogs (and no cats… actually the signs say no pets) at Boca Chita… the rangers have always enforced this. If they see a pet on a boat, they will have you leave, right away. I’ve heard that people who argued or delayed leaving have been fined.
You can safely take in 5′ draft at MLW, just stay bewteen the 3 sets of buoys. The shallowest part, just over 5′ MLW, is just east of the final pair (between the last pair and the harbor entrance).
Mosquitoes make the place unbearable in summer though…
