About Southwest Hills

Southwest Hills is a residential neighborhood in western San Marcos, Texas (Hays County), situated in the wooded hills northwest of Wonder World Drive and southwest of Post Road. The neighborhood has approximately 826 residents and developed organically over several decades rather than as a single master-planned community. Most homes were built between 1970 and 1999, with additional construction from the 2000s to the present. The area is not a gated community and is not governed by a single master-plan HOA.

Housing in Southwest Hills consists primarily of single-family homes in traditional and ranch styles, often featuring limestone or brick exteriors with attached garages or carports. The neighborhood includes a mix of smaller two-bedroom residences and larger four-bedroom properties. The area sits in the rolling terrain of the Texas Hill Country, with mature tree cover and wooded lots throughout. Craftsman bungalows, Cape Cod designs, and custom homes are also present in the housing stock.

San Marcos is located along I-35 approximately 32 miles south of Austin and serves as the seat of Hays County. Texas State University, which enrolled a record 44,596 students for fall 2025, anchors the local economy and gives the city its college-town character. The San Marcos River, fed by springs that maintain a constant 72-degree temperature year-round, runs through the city and supports tubing, kayaking, and swimming. San Marcos was ranked the nation's fastest-growing city by the U.S. Census Bureau for three consecutive years (2013 through 2015), and the city's population reached approximately 90,988 as of January 2025. The community is served by San Marcos Consolidated Independent School District.
