About Corner Tubes

The 72-degree spring-fed waters of the Comal River snake through New Braunfels, throwing reflected light on tree branches that crane over the banks. One of the shortest navigable rivers in the United States, it stays a constant 72 degrees year round. Corner Tubes outfits visitors with black inner tubes or new vinyl tubes, letting them float down the river at a leisurely pace, then ride a shuttle from the last public river exit back to the entrance.
