By far the most diversified grouping of the outer islands of the Florida Keys, is the Dry Tortugas. They are also the most challenging to visit. However, these islands offers much to the beholder that is willing to take the path less traveled. Fort Jefferson is the most visited island of the Dry Tortugas and offers a historical look into the Civil War era and is a marvel of a brick structure - so massive that it can easily be seen from space. The fort is actually located on the island named Garden Key and it is the only place that the contracted ferry and seaplane are allowed to transport guest to and fro. All other islands and areas of interest are only accessible to the Park Rangers, your willing yachting friend or a private charter like ours. Everyone checks in with the Park Ranger at Garden Key when they arrive within the park's boundary. Private vessels are required to pay park fees for themselves and any guests aboard. Private charters (any vessel transporting paying guests) must hold a special permit to enter the National Park and we suggest verifying the legitimacy of any charters offering such a trip.
