The Six Mile Cypress Slough Preserve is a 3,500 acre wetland, located in Fort Myers, Florida, which filters rainwater on its way towards Estero Bay. The preserve contains a 1.2-mile boardwalk trail, interpretive center, and amphitheater. The slough is a nine mile long, one-third of a mile wide, wildlife corridor, providing a safe way for animals to travel within the Fort Myers city limits. A 57-square-mile watershed drains into the slough.
