Collier-Seminole State Park near Naples sits on the edge of the Big Cypress region and offers a look at a wilder, more tropical side of southwest Florida. Royal palms, mangroves and pine flatwoods create a varied landscape rich in wildlife. Visitors can paddle kayak trails through mangrove tunnels, hike woodland paths and see the historic Bay City Walking Dredge, a unique machine used to build the Tamiami Trail. The campground makes it easy to stay overnight and enjoy the quiet. Entry is $2 to $6 per vehicle, camping runs $16 to $40 per night, and tours cost extra. Bring insect repellent, especially in summer.
