A stone's throw from the western tip of Elliott Key and 9 miles southeast of Convoy Point, the island is open for day use. It was the onetime site of the Cocolobo Club, a yachting retreat famous for hosting presidents Harding, Hoover, Johnson, and Nixon as well as other luminaries. Hurricane Andrew blew away what remained of club facilities in 1992. Adams Key has picnic areas with grills, restrooms, dockage, and a short trail running along the shore and through a hardwood
hammock. Rangers live on-island. Access is by private boat, with no pets or overnight docking allowed.
