How To Float The Guadalupe River For Free

The Guadalupe River is public water — anyone can float it without paying an entrance fee. In that sense, floating the Guadalupe is free. But in practice, most people pay $15–25 for a tube rental that includes parking and shuttle service back to their car. This guide covers how to access the river, what the costs actually look like, and the rules you need to know before you go.

Where the Tubing Happens

The main tubing section of the Guadalupe River runs through the Texas Hill Country between Canyon Lake Dam and the city of New Braunfels, roughly an hour northeast of San Antonio and about three hours west of Houston. Most outfitters are clustered along River Road (FM 306 and the roads branching off it) in the Canyon Lake area, just outside New Braunfels city limits. This distinction — inside vs. outside city limits — matters a lot for the rules about what you can bring (more on that below).

The most popular stretch is the Horseshoe Loop, a roughly one-mile U-shaped bend in the river. Most outfitters offer a short float (Horseshoe Loop only, typically 1–2 hours), a medium float (1–1.5 miles), or a long float (2.5+ miles, roughly 3–5 hours depending on water flow). At low water, floats take longer; at higher flows, everything speeds up.

What’s Actually Free (and What Costs Money)

Free: The river itself. Under Texas law, navigable rivers are public. You do not need a permit or pass to float the Guadalupe.

Not free: Tube rental ($20–25 per tube at most outfitters), cooler tubes ($10–15), parking, and shuttle service. Most outfitters bundle parking and shuttle into the tube rental price. If you bring your own tube, you still typically pay the same price at most outfitters because you’re paying for parking and shuttle access, not just the tube itself.

To float for truly free, you would need your own tube (or float), access to a public river entry point, and someone to shuttle you or a plan to walk back. Public access points do exist — Guadalupe Park (operated by the US Army Corps of Engineers) offers free year-round access to the river below Canyon Dam — but most people find the outfitter fee worth the convenience of parking, shuttle, and a guaranteed put-in and take-out point.

Choosing a River

The San Marcos, Comal, Guadalupe, and Frio rivers are the four main tubing rivers in central Texas. Each has a different character.

The Comal River in New Braunfels is the shortest and most beginner-friendly — spring-fed, consistently clear, and relatively gentle. It flows through town, so access is easy. The Guadalupe River is longer, has more rapids and faster-moving sections, and draws a rowdier crowd. The San Marcos River near San Marcos is spring-fed and scenic with a single-use container ban. The Frio River in the western Hill Country (Concan area) is the most remote and least crowded, but it’s a longer drive — about 4 hours from Houston, 2 hours from San Antonio.

Container Rules (Read This Carefully)

This is the most important thing to understand before you float, and getting it wrong can cost you $500.

Inside New Braunfels city limits (applies to the Comal River and the portion of the Guadalupe inside city limits): All disposable containers are banned. That means no aluminum cans, no plastic water bottles, no fast food wrappers, no paper bags, no Styrofoam — nothing designed to be thrown away after a single use. You must use reusable containers: insulated tumblers, canteens, reusable water jugs. The fine is up to $500. Alcohol is still allowed, but it must be in a reusable, non-disposable container.

Outside New Braunfels city limits (Canyon Lake area, where outfitters like Tube Haus, River Sports Tubes, and others are located): Cans are allowed. Glass and Styrofoam are banned on all Texas waterways statewide. Plastic containers of 5 ounces or smaller (like jello shot cups) are also banned. Most outfitters outside city limits will prominently advertise “No Can Ban Here” — that’s what they’re referring to.

If you want to bring a cooler full of canned beer with no hassle, choose an outfitter outside New Braunfels city limits in the Canyon Lake area. If you float within the city, bring everything in reusable containers.

What to Bring

Water shoes or sport sandals — the river bottom is rocky and uneven, and you’ll need to walk at put-in and take-out points and possibly through shallow sections. Flip-flops fall off easily and don’t protect your feet. Secure shoes are essential.

Sunscreen — and reapply frequently. You will be in direct sun for hours. A lightweight long-sleeve shirt or rash guard is worth considering. Bring a hat and sunglasses (secured with a strap so you don’t lose them to the river).

Water and snacks — dehydration is common, especially if you’re drinking alcohol in the Texas heat. Bring more water than you think you need. Fruit (watermelon, grapes) travels well on the river.

A waterproof bag or dry bag — for your phone, keys, and wallet. Tie it to your tube, not to the cooler. Ziplock bags are not reliable enough.

A cooler with a tube — most outfitters rent cooler tubes separately ($10–15). A medium-sized cooler is easier to manage than a large one, especially in rapids. Tie everything together with rope or carabiners — tubes, cooler tube, and your group. Outfitters usually sell rope at the rental counter.

A mesh trash bag — most outfitters provide free trash bags at launch. Take one and use it. Littering on Texas waterways is illegal and can result in fines.

Safety

The Guadalupe River is not a lazy river. It has rapids, rocky sections, submerged obstacles, and currents that vary depending on water releases from Canyon Dam upstream. Multiple drownings occur on central Texas rivers most summers. Take it seriously.

Life jackets: When river flow exceeds 500 cubic feet per second (cfs), life jackets are mandatory for all children under 8. When flow exceeds 750 cfs, life jackets are mandatory for everyone. Outfitters provide life jackets free of charge on request — ask for them regardless of flow levels if you or anyone in your group is not a strong swimmer.

Canyon Dam releases: Water is released from Canyon Dam upstream, which can cause sudden changes in water level and current speed. Check current river flow conditions before you go.

Children: Most outfitters and the city of New Braunfels require children to be at least 6 years old to float the Guadalupe (some outfitters set the minimum at 5, but this can change with water conditions). Children must be accompanied by an adult, must be able to swim, and should wear life jackets. Weekdays and Sundays tend to be less crowded and better for families with kids.

In shallow sections and rapids, lift your body up in the tube to avoid scraping your legs and back on rocks. This is the most common source of cuts and bruises on the Guadalupe. A tube with a mesh bottom helps but doesn’t eliminate the problem.

Outfitters

There are dozens of tube rental outfitters in the Canyon Lake and New Braunfels area. Prices are similar across the board ($15–25 per person). What varies is location on the river, float length, shuttle quality, and whether you’re inside or outside the disposable container ban zone. Some well-established outfitters include Tube Haus (operating since 1978, located at the start of the Horseshoe Loop in Canyon Lake), River Sports Tubes, Rockin’ R River Rides (multiple locations on both the Guadalupe and Comal), Rio Guadalupe Resort, and Floaties on the River. Most outfitters include parking and shuttle in the tube rental price. Arrive before noon on summer weekends to avoid long waits.

When to Go

The tubing season runs roughly from March through September, with peak season in June, July, and August. Water temperature in the Guadalupe stays relatively cool year-round because it’s fed by releases from Canyon Lake, but air temperatures in the Texas Hill Country regularly exceed 100°F in summer. Weekends and holidays (especially Memorial Day, Fourth of July, and Labor Day) are extremely crowded. For a more relaxed float, go on a weekday or early in the season. Check river flow levels before your trip — very low water means a slow, rocky float with a lot of walking, while very high water can be dangerous and may close the river entirely.
