San Marcos

About San Marcos

San Marcos is a vibrant cold spring located in the heart of Texas between San Antonio and Austin. Fed by the crystal-clear San Marcos River, it offers a refreshing retreat with cool, pristine water that tempts swimmers and floaters alike. This hybrid spring combines natural beauty with easy access and enjoyable amenities, making it a standout among hot springs in Texas and sought-after Texas swimming holes.

Getting There

You reach San Marcos easily by car, with drive-up access and ample parking available near popular entry points like Sewell Park and Rio Vista Park. There's no hiking involved, allowing you to arrive relaxed and ready to dive straight into the water. Its location alongside I-35 makes it a convenient stop for travelers heading through central Texas.

What to Expect

The water is consistently cool and clear, creating an invigorating experience as you swim or float along the gentle current. Cheatham Street Dam, also known as Rio Vista Falls, provides an eye-catching cascade that draws visitors statewide. Because the river runs through public parks, you’ll find a lively atmosphere filled with families and groups sharing the space, especially on warm summer days. Facilities are basic but functional, focusing on preserving the natural charm.

Tips for Visitors

Visiting during summer means you can beat the chill of the water while enjoying the bustling scene. Bring your own tube or rent one at Sewell Park to float effortlessly downstream. There’s no fee to enter, but expect crowds on sunny weekends. Note that clothing is optional in some areas, so be prepared and respect local customs to ensure a comfortable visit.
