The Six Mile Cypress Slough Preserve is over 3,500 acres of wetland ecosystem with a Boardwalk trail and Interpretive Center. The cypress slough catches and slowly filters rainwater on its way towards Estero Bay. A myriad of animals like otters, alligators, turtles, wading birds, and more live at the Slough year-round. Others, like migrating birds and butterflies, use the Slough as a feeding area or a winter home.
