Blanco River
Joins the San Marcos a few miles down stream. It's not as big or visited as the San Marcos.
San Marcos River
The river that made the city runs through town. There are many parks and restaurants along the river, and it's pretty much impossible to see any of San Marcos without seeing a lot of the river.
