Myakka River State Park One of the oldest and largest state parks, Myakka protects one of the state's most diverse natural areas. The Myakka River, designated as a Florida Wild and Scenic River, flows through 58 square miles of wetlands, prairies, hammocks, and pinelands. Visitors can enjoy wildlife viewing from a boardwalk that stretches out over the Upper Myakka Lake, then take to the treetops with a stroll along the canopy walkway.
