The Guadalupe River runs from Kerr County, Texas to San Antonio Bay on the Gulf of Mexico. It is a popular destination for rafting, fly fishing, and canoeing. Larger cities along it include Kerrville, New Braunfels, Seguin, Gonzales, Cuero, and Victoria. It has several dams along its length, the most notable of which, Canyon Dam, forms Canyon Lake northwest of New Braunfels.

The upper part, in the Texas Hill Country, is a smaller, faster stream with limestone banks and shaded by pecan and bald cypress trees. It is formed by two main tributary forks, the North Fork and South Fork Guadalupe Rivers. It is popular as a tubing destination where recreational users often float down it on inflated tire inner tubes during the spring and summer months. East of Boerne, on the border of Kendall County and Comal County, it flows through Guadalupe River State Park, one of the more popular tubing areas along it.

The lower part begins at the outlet of Canyon Lake, near New Braunfels. The section between Canyon Dam and New Braunfels is the most heavily used in terms of recreation. It is a popular destination for whitewater rafters, canoeists, kayakers, and tubing. When the water is flowing at less than 1,000 cu ft/s (28 m3/s) there could be hundreds if not thousands of tubes on this stretch of it. At flows greater than 1,000 cu ft/s (28 m3/s), there should be very few tubes on the water. Flows greater than 1,000 cu ft/s (28 m3/s) and less than 2,500 cu ft/s (71 m3/s) are ideal for rafting and paddling. The flow is controlled by Canyon Dam, and by the amount of rainfall the area has received. It is joined by the Comal River in New Braunfels and the San Marcos River about two miles (3 km) west of Gonzales. The part below the San Marcos River, as well as the latter, is part of the course for the Texas Water Safari.
