Mound Key

Mound Key Archaeological State Park is located in Estero Bay, near the mouth of the Estero River. The park systems manages 113 of the island’s 125 acres. The park is a gathering of mounds and accumulated shell, fish bone, and pottery middens that climb over 30 feet above the bay’s waters.
Mound Key was an important setting of the Calusa tribe. Most experts believe it was where Calos, their capital, was located. The Mound Key Site on the island was placed in the U.S. National Register of Historic Places on August 12, 1970. The island can only be reached by boat from the Koreshan State Historic Site or Lovers Key State Park


Recreational Activities 
The park offers activities such as boating, fishing, wildlife viewing and interpretive exhibits. Nature trails and information kiosks are in development, but the park currently has no restroom facilities. Interpretive displays can be found on a trail that runs the full width of the island. The park is located in Estero Bay, a few miles by boat from both the Koreshan State Historic Site and Lovers Key / Carl E. Johnson State Park.
