Upper Comal River

The Comal River, known as one of the shortest rivers in the US, is a spring-fed waterway sourced from the Edwards Aquifer. Flowing 2.5 miles through the City of New Braunfels, it eventually merges with the Guadalupe River. Diving enthusiasts can embark on their underwater exploration from just downstream of the Wurstfest Grounds, extending to a short distance before the Tube Chute.

When you dive in the Comal River, you'll encounter a diverse range of aquatic life. The river is home to Bass, Bluegill, Rio Grande Cichlid, and Blue Tilapia. Alongside these fascinating creatures, you'll also find native vegetation such as Cabomba, Ludwigia, and Vallisneria.

For diving enthusiasts, the maximum depth within the diving area of the river is approximately 15ft, varying depending on the water flow. Access to the diveable section of the river is located on the north shore of the south spur of the river, at the western end of the park. It extends eastward until the north spur entrance, where a convenient large staircase facilitates water exit. It is important to note that it is not advisable to continue eastward towards the Tube Shoot due to potentially hazardous currents that can make swimming against the flow challenging.

The Comal River offers divers with a visibility of 4 meters, and a maximum depth of 4 meters. It caters to divers of all levels, from beginners to advanced. Located in New Braunfels, Comal County, Texas, the river serves as a captivating dive site in the United States.
