San Marcos River

The San Marcos River bubbles to life from hundreds of springs right in the City's center. Always a refreshing 72 degrees, the river is enjoyed year ‘round. 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 soak up some sun. For a complete list of park tips and rules, please check HERE.
