Comal River

The Comal River, located in New Braunfels, TX, is the state's shortest navigable river and, at around 2 miles long, one of the country's shortest boatable waterways. Affectionately called the “Longest Shortest River in the World” by locals, the river's entire length runs within the city limits.

A tributary of the Guadalupe River, the headwaters of the Comal River originate from Comal Spring inside Landal Park. Thanks to the river's water temperature holding at a refreshing 70 to 72 degrees year-round, lazily floating can be a great way to cool off on those hot summer days.
