San Marcos River - Course

Course

The river begins at San Marcos Springs, rising from the Edwards Aquifer into Spring Lake. Access to much of the headwaters is restricted because of the delicate ecosystem and numerous rare species. The upper river flows through Texas State University and San Marcos, and is a popular recreational area. It is joined by the Blanco River after four miles, passes through Luling and Palmetto State Park. Near Gonzales it flows into the Guadalupe River after a total of 75 miles (121 km). This course is the first section of the Texas Water Safari.
