The Mule Keys are a group of scattered islets in the Florida Keys in Monroe County, Florida, United States. They are between 3 and 12 miles (4.8 and 19.3 km) west of Key West, separated from it by the Northwest Channel. On the west, they are separated from the Marquesas Keys by the 6-mile (9.7 km) wide Boca Grande Channel. They belong to the outlying islands of the Florida Keys. Administratively, they are an unincorporated area of Monroe County. The islets are part of the Key West National Wildlife Refuge. The area of the islets totals 1.07 sq mi (2.8 km2), of which 1.02 sq mi (2.6 km2) are land area and 0.05 sq mi (0.13 km2) inland water bodies (on three of the keys). The islets are uninhabited except for Mule Key, for which the census of 2000 lists one housing unit with a population of two (park rangers or coast guard).

The location of Barracouta Keys and Marquesas Keys in the Key West National Wildlife Refuge.

The United States Government has placed most of this area off limits, as a part of the Key West National Wildlife Refuge. It is even prohibited to anchor off Man Key and Woman Key in the sand, although Woman Key was a popular destination for day trippers from Key West in the past, which Boca Grande Key still is. Anchoring off the south part of Boca Grande Key is also prohibited; it is permitted only off the northwest portion.[1]

Ballast Key was privately owned by Key West developer David W. Wolkowsky. After Wolkowsky's death in 2018, the island was donated to The Nature Conservancy, which in turn deeded ownership of the land to the United States Fish and Wildlife Service. [2]

The easternmost islet, Mule Key, is 2.7 miles (4.3 km) west of Sunset Key which is part of Key West city. The westernmost (and largest) islet, Boca Grande Key, is 6 miles (10 km) east of the Marquesas Keys.

   no exact separate area figures are available. Joe Ingram Key is estimated at 10,000 m2.

On nautical maps, the Mule Keys appear like an atoll of 11 miles (18 km) length east–west, and 6 miles (9.7 km) width north–south (covering a sea area of roughly 58 sq mi (150 km2), with Mule Key, Crawfish Key, Man Key, Ballast Key, Woman Key and Boca Grande Key along the southern rim (from east to west), and Cottrell Key in the north.

7 miles (11 km) south of Mule Key, separated from the Mule Keys by West Channel, are three notable submerged reefs, from east to west:

  1. Eastern Dry Rocks, at 24°27′42.6″N 81°50′38.1″W / 24.461833°N 81.843917°W / 24.461833; -81.843917 (Eastern Dry Rocks)
