In 1836, Indian Key became the first county seat for Dade County. At that time, this tiny island was the site of a lucrative business-salvaging cargo from shipwrecks in the Florida Keys. Accessible only by boat, visitors come here to swim, sunbathe, and hike. Boat and kayak rentals are available from Robbie's Marina at (305) 664-9814. Located on the oceanside of U.S. 1 at Mile Marker 78.5.
