San Marcos - More than Just a Pretty Face

San Marcos is a natural beauty and the most intriguing feature is its river. The beautiful and delicate environment of the  San Marcos River bubbles to life from hundreds of springs right in the center of town. Always a refreshing 72 degrees, the river is enjoyed year-round so be sure to take extra care when playing in and around its waters to protect its ecosystem. Grab a tube and go for a float. Rent a kayak or stand-up paddle and navigate its length. Bring your snorkel and discover its depth. Or just bring a picnic and soak up some sun.

If you'd rather stay on dry land, we've got you covered. Bring your bike, binoculars, or man's best friend to explore scenic parks right in the heart of town. Native wildlife and migratory birds abound in the more than 2,100 acres of natural areas in San Marcos' city limits. Choose from ADA-accessible trails with information kiosks and benches, to miles-long natural trails for the more adventurous. Just remember to stay on the marked trails so these beautiful natural areas can be enjoyed for generations to come.

San Marcos' beauty is more than just surface deep. We take stewardship of the river and natural areas to heart, protecting the Edwards Aquifer and the eight endangered or threatened species native to this area. This way when you come back to visit, it will be just as good as your first time.
