Geography of San Marcos

San Marcos sits primarily in Hays County, where it serves as county seat, with small portions extending into Caldwell and Guadalupe Counties. The city sits directly on Interstate 35, roughly 30 miles southwest of Austin and about 51 miles northeast of San Antonio — putting it squarely in the fastest-growing stretch of highway in Texas. With a 2024 population estimate near 77,000, up more than 70% since 2010, San Marcos was named the fastest-growing city in the United States by the Census Bureau for 2013-2014 and hasn't slowed down much since.

Free towing is included anywhere in San Marcos and the surrounding area. You can find more about local services on the City of San Marcos's official website.

History of San Marcos

San Marcos takes its name from Spanish explorer Alonso de León, who reached the river in 1689 on the feast day of St. Mark the Evangelist. Anglo-American settlement began in 1846, and the town was officially platted in 1851. The city's early economy centered on grain milling and cotton ginning, and after the railroad arrived in 1880, cattle and cotton shipping became the backbone of local commerce for decades.

Culture of San Marcos

San Marcos today runs on a mix of higher education, retail tourism, and logistics. Texas State University, founded in 1899, set an all-time enrollment record for fall 2025 at 44,596 students and generates an estimated $8 billion in statewide economic impact annually. The San Marcos Premium Outlets and Tanger Outlets draw an estimated 6 million shoppers a year and account for roughly 45% of the city's total sales tax revenue, while Amazon's fulfillment center is now the area's largest private employer.

San Marcos sits at the confluence of the San Marcos and Blanco Rivers, and that geography turned catastrophic over Memorial Day weekend in 2015, when a flash flood sent the Blanco River from under 15 feet to a crest of 43.08 feet in hours — the river reportedly rising 5 feet every 15 minutes at one point in nearby Wimberley. The flooding killed at least 12 people in Hays County and destroyed more than 2,000 homes, and the city was still spending federal recovery and mitigation funds — an estimated $58 million — a decade later.
