A notable army and cavalry post from 1852 to 1946, Fort Clark has since evolved into a unique real estate development and resort with good amenities for the traveler. There are 1,600 acres of wilderness here, populated by whitetail deer and wild turkeys, crosscut by miles of nature trails, and featuring a behemoth spring-fed swimming pool (Texas's third largest) and two golf courses. There's also a museum, a basic motel ($30-$50 for a double), and an RV park (about $22 for a site with full hookups).
