St. George Island State Park protects nine miles of undeveloped barrier-island beach on Florida's Gulf coast. The wide, white-sand shore, rolling dunes and clear water are regularly ranked among the best beaches in the United States. Visitors can swim, fish, shell and watch birds, and hiking trails lead through pine forest and salt marsh. A campground offers a relaxed way to stay near the water, and the quiet, natural feel of the park is a big part of its charm. Entry is $6 per vehicle. It is a wonderful choice for anyone who wants a beach experience without crowds.
