Mild currents, clear water, and a host of treasures left behind by tubers make the river an ideal location for tubers & scuba diving. Because the Comal maintains a temperature of approximately 72 degrees Fahrenheit (approximately 22 degrees Celsius) year round, divers are present in both the summer and the winter. Thousands of people from all walks of life tube down the Comal River in the spring & summer to enjoy the river's natural beauty. Tubing on the Comal provides another relaxing alternative to tubing on the nearby Guadalupe river & The Schlitterbahn Water Park.
