San Marcos Municipal Airport is centrally located near Interstate 35, just three miles from downtown San Marcos, Texas, 25 miles from the State Capitol of Austin and 45 miles from San Antonio. The airport is popular among pilots, with its three asphalt runways, each more than a mile in length and aligned in a way that virtually eliminates crosswind operations.
