Paddling in Dry Tortugas National Park

Dry Tortugas sits nearly 70 miles west of Key West in the Gulf of Mexico — a 100-square-mile park that is almost entirely open water, with seven small coral and sand islands rising just above the surface. Less than one percent of the park is dry ground.

That ratio tells you everything about what paddling here means: you are on the open ocean, not a protected bay, reading wind and current the whole time. Garden Key is the hub.

The dinghy beach, tucked between the main dock and the old south coaling dock, is the launch point for all kayak and paddleboard trips.

Before you enter the water, park rangers will give you a briefing — if no one meets you on arrival, seek out staff before launching.

A free boating permit is required for all vessels, including kayaks and paddleboards; pick it up in person at the visitor center or park headquarters on Garden Key.

The short loop around Bush Key and Long Key takes a few hours and suits paddlers getting their bearings. These low islands are bird nesting habitat, and landing on them is not permitted — a kayak lets you work the shoreline closely without setting foot ashore.

Loggerhead Key, the largest island in the park, lies 3 miles to the west of Garden Key across deep, open water with strong cross-currents. Rangers have documented rescues of paddlers swept off course on that crossing.

The trip takes roughly two hours out and longer coming back against the current. Loggerhead access is capped at 24 people per day and must be listed on your boat permit.

Calm conditions are most reliable in summer, June through September, though heat and humidity are intense. Winter weather can be fine — mild waves and good visibility — but it is not guaranteed, and a front can change things fast.

Required gear for every paddle trip: a PFD, a signaling device, and a portable VHF radio. Bring all of it from the mainland. There are no services, no rentals, and no rescue infrastructure on the water.

If you're transporting a kayak on the Yankee Freedom ferry, space is limited to three boats per trip and hulls must be under 17 feet — reserve well ahead. Kayak spaces are available to campers only, not day visitors.

The water here is clear enough to watch seagrass and coral pass beneath your hull. That clarity is also a reminder of what the permit system and zone closures are protecting.

Check with rangers about any restricted areas before you go, and check back in when you return.
