Our office, located at Mile Marker 21.5 on Cudjoe Key.
This area basically covers from just outside Key West (MM 4) eastward to the Big Pine Key area, or about Mile Marker 33. The Keys are traversed by only one road, US Highway 1, and almost everything is identified by Mile Marker references, usually shown as MM. Each island can be found along US 1 with the MM references showing it's relationship to Key West or MM 0. The Island Profile pages of this site will help you get an idea of just where each Key is and how it relates to Key West and the other Keys as well as the spectacular diving and snorkeling of Looe Key Reef National Marine Sanctuary, and other offshore reefs.
