Pulaski Shoals marks the northeast edge of Dry Tortugas National Park, a spread of shallow coral heads where the shoals claimed many ships before charts and navigation aids. Divers go for the big animals along the deeper reef edge: large grouper, sharks, turtles and formations of eagle rays.

Also known as Pulaski Shoal, Pulaski Reef, Pulaski Shoals Area.

The dive

Inside the park boundary the reef is a field of scattered, very shallow coral heads. Among them lie the scattered remains of a wide variety of shipwrecks, ships these shoals claimed in the days before navigational aids and accurate charts.

For a deeper dive, divers go just beyond the boundary buoys to 23–24 m (75–80 ft) and follow that depth curve, looking for changes in reef elevation. Descending into the deep blue water, they meet very large grouper, plenty of snapper and often sharks: black tips, hammerheads, bull and nurse sharks are all common, along with turtles and large formations of eagle rays.

Season follows Key West: Boats dive all year; May to October brings the warmest water and best visibility, but August to October is hurricane season.

Know before you go

  • Currents at the shoals are strong and variable in direction.
  • The site is remote: a diver in trouble here is a long way from help.
