Staying on East Sister Rock Island?
The Old Seven Mile Bridge and Pigeon Key are about 3 miles from the mainland dock in Marathon where guests come ashore. East Sister Rock Island sits a quarter mile offshore, and guests run the included 21-foot Carolina Skiff across themselves — about five minutes each way, on their own schedule.
