The Guadalupe River runs from Kerr County, Texas, to the San Antonio River near the Gulf of Mexico. The river is a popular destination for rafters and canoers. Larger cities along the river include New Braunfels, Kerrville, Seguin, Gonzales, Cuero, and Victoria. The Guadalupe has several dams along its length, the most notable of which forms Canyon Lake northwest of New Braunfels.
The upper river, in the Texas Hill Country, is a smaller, faster stream with limestone banks and shaded by pecan and bald cypress trees. The upper Guadalupe is popular as a tubing destination where recreational users often float down the river on inflated tire inner tubes during the spring and summer months. East of Boerne, on the border of Kendall County and Comal County, the river flows through Guadalupe River State Park, one of the more popular tubing areas along the river.
The lower river 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 and kayakers. The flow varies according to the seasons, and by the amount of rainfall the area has received. It is joined by the Comal in New Braunfels and the San Marcos River about two miles west of Gonzales. The Guadalupe below the San Marcos River is part of the course for the Texas Water Safari.
Shortly before reaching the Gulf of Mexico, the Guadalupe flows into the San Antonio River near San Antonio Bay.
Shaded by pecan and bald cypress trees.
The Guadalupe River is listed as one of the 100 top trout streams in the United States. In addition to fly fishing for rainbow and brown trout on the tail-waters of the Guadalupe River below Canyon Lake, anglers can catch largemouth bass, smallmouth bass, Guadalupe bass, white bass, and the Rio Grande perch.
