San Marcos River

The vibrant and delicate ecosystem of 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. It is also home to several threatened or endangered species, so be sure to take extra care when playing in and around its waters. 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. And as always, be sure to pack out all that you have brought with you.
