The Little Manatee River begins in a swampy area near Fort Lonesome and flows almost 40 miles before emptying into Tampa Bay. The river has been designated an Outstanding Florida Water and is part of the Cockroach Bay Aquatic Preserve. Visitors can fish along the banks of the river. Wildlife enthusiasts can enjoy hiking a six-and-a-half mile trail through the park's northern wilderness area. For those who prefer their hikes on horseback, the park has 12 miles of equestrian trails and four equestrian campsites. Campers can spend the night in a full-facility campground or hike out to a primitive campsite along the trail. A youth/group campground accommodates up to 20 people. The scenic picnic area along the river has tables, grills, and pavilions. Pavilions can be reserved for a fee. Unreserved pavilions are available on a first-come-first-served basis.
