Also called Las Moras Springs, these fill a 300-foot-long pool, among the largest in Texas. There’s a separate pool for the kids. The springs themselves release 12 to 14 million gallons of sparkling, 68-degree water every day, year-round.
The water flows over several spillways to form Las Moras Creek, which joins the Rio Grande 29 miles from here. Fort Clark, a cavalry post established in 1852 to protect the San Antonio to El Paso Road, closed in 1946, and in 1971, became a private re-tirement and recreation community. For pool privileges, make a reservation for your RV, or book a night in one of the motel rooms in what used to be the fort’s cavalry barracks. You’ll also have access to 31 historic buildings on this National Historic Site, along with a museum, par-3 golf course, and 52 miles of trails for hiking and biking. Work up a sweat, then refresh yourself in the pool.
Fort Clark Springs is on US 90 in Brackettville. For pool access, make motel or RV-site reservations; call 830/563-2493.
