The spot
The things that stay true when the weather changes.
No. Key Largo, FL is reached by boat, so it is not a shore snorkel.
Key Largo, FL runs roughly 15 to 65 feet deep in the area people use.
The clearest water is on the outer reefs nearer the Gulf Stream. Visibility typically runs 25 to 100 ft and averages about 50.
