About This Place
San Marcos is a city in the U.S. state of Texas, and is the seat of Hays County. Located within the Austin–Round Rock–San Marcos metropolitan area, the city is located on the Interstate 35 corridor—between Austin and San Antonio.
Founded on the banks of the San Marcos River, the area is considered to be among the oldest continuously inhabited sites in the Northern Hemisphere. San Marcos is home to Texas State University–San Marcos, and the Aquarena Center. The population was 50,371 in 2008. San Marcos was listed in the 2010 Business Week's fourth annual survey of the "Best Places to Raise your Kids."
Archeologists have found evidence at the San Marcos River associated with the Clovis culture, which suggests that the river has been the site of human habitation for more than 10,000 years. The headwaters of the cool, clear river are the San Marcos Springs, fed by the Edwards Aquifer. The San Marcos Springs are the thirty largest collection of springs in Texas. Never in recorded history has the river run dry.
