Are Beer Cans Allowed on Texas' Rivers when Floating

Updated: Mar 8

Updated March 2024 to reflect recent changes in San Marcos:

Some central Texas rivers have issued a can ban, prohibiting disposable containers such as beer cans while tubing, while some are still allowing them. We break down the laws regarding the San Marcos river (which we float), the Comal, and the Guadalupe river so you can float without worry of issue or citation.

Enjoying a cold beer on the San Marcos river


The city of San Marcos has recently passed their own "can-ban" covering portions of the San Marcos river, taking effect May 2024. For us at Frontera Tours, and those who float through places such as Texas State Tubes and Don's, cans are still allowed on the San Marcos river for 2024 and beyond. Glass and Styrofoam are still not allowed, however the can-ban only covers the river section running through the city limits, which we do not float.

If y'all join a float trip with Frontera Tours, we provide onion mesh bags to everyone for trash. It's a great way to float the river and keep your trash on board. At the end we'll have trash cans and recycling bins for everyone. Do your part to keep the river clean!


No disposable Containers are allowed on the Comal River: All “throw away" and/or "one time use” drink containers, food packaging and wrappers, are prohibited, banned, and outlawed on the Comal River. Keep this in mind when planning a float trip on the Comal.

This rule is also known as the "New Braunfels Can Ban". Examples of disposable containers are one time plastic water bottles, Ziploc plastic baggies, plastic forks, spoons, knives, paper cups, plastic cups, styrofoam cups and containers, all glass items, beverage cans, one time use mini kegs, food wrappers and packaging, plastic wrap, plastic trash bags, aluminum foil, wine boxes, juice boxes, paper plates, paper towels, napkins, etc.

We recommend taking a couple yeti insulated bottles and filling them up with your favorite beverage.

Guadalupe River

The Guadalupe river has numerous floating areas, and depending on which you choose you will possibly encounter a can-ban. Within the city limits of New Braunfels, the can-ban is still in effect as it is on the Comal river. Areas outside of the city limits only enforce laws related to glass and styrofoam. For more information about the Guadalupe laws, see this site provided by the city of New Braunfels or check with your preferred river outfitter. There are too many to mention here but we prefer Rockin' R Rentals and Mountain Breeze Camps for our floating trips to the Guadalupe.

Plan Ahead

No matter which river you choose to float, it's always a good idea to call ahead to be sure of the local laws before packing your coolers. You can be sure when booking a float with Frontera Tours that you will not be affected by any can-bans. Do your part to keep the river clean, pack out what you pack in!
