River Overview
The Guadalupe River is the adventure pick of the three major tubing rivers near Austin. Located just below Canyon Lake Dam — about an hour south of Austin — it offers crystal-clear, dam-released water that's noticeably cooler than the spring-fed San Marcos and Comal rivers. Water temperatures run 65–68°F — refreshing on a hot day, but you'll feel it.
The Guadalupe has a different vibe from the other rivers. It's more rural, more rugged, and more adventure-oriented. The riverbanks are lined with tall cypress trees, limestone bluffs, and thick Hill Country vegetation. There are sections with mild rapids, rocky stretches, and deeper pools. It's the river you choose when you want more than just a lazy float — though lazy floating is absolutely an option too.
Critical detail: The Guadalupe below Canyon Lake is dam-controlled. The water level depends on how much water the Army Corps of Engineers releases from Canyon Lake Dam. In wet years, the flow is strong and the floating is excellent. In drought years, sections can run too low to tube. Always check conditions before going. The USGS gauge at Sattler is your best resource — if the flow is below 50 cubic feet per second, the float will be a drag (literally). Not sure which river to pick? Our river comparison guide breaks it all down.
The Horseshoe Loop Explained
The Horseshoe Loop is the Guadalupe's signature feature, and it's unlike anything on the San Marcos or Comal. Here's how it works:
The river makes a giant U-shaped bend that curves about a mile downstream before looping back to almost exactly where it started. Picture a horseshoe — you float down one side, around the bend, and up the other side, ending up just a short walk from your starting point. No shuttle. No pickup. You just walk back and do it again.
Each lap of the Horseshoe Loop takes about 45 minutes to 1 hour, depending on the water flow. You pay one tube rental fee (typically $20–$25) and float it as many times as you want, all day long. Most people do 3–5 laps. It's the most budget-friendly tubing experience near Austin — and because you're floating the same scenic stretch, you can leave your cooler, chairs, and gear at the put-in point.
For first-timers: the Horseshoe Loop has a few spots with mild rapids and rocky sections. Nothing dangerous, but you'll occasionally need to push off rocks or lift your tube over shallow areas. Water shoes are essential here — the river bottom is rockier than the San Marcos or Comal. See our complete packing list for gear recommendations.
Float Options
The Guadalupe offers more variety than the other two rivers. You can customize your float based on how much time and adventure you want:
- •Short: Horseshoe Loop only (~45 min per lap). Pay once, float all day. No shuttle needed. Best value option. Ideal for camping trips where you want to float at your own pace.
- •Medium: 2-hour section. A one-way float that includes some beautiful stretches beyond the Horseshoe. Shuttle back to the starting point. Good balance of length and adventure.
- •Long: 3–4 hour full float. The complete Guadalupe experience. Deeper pools, more rapids, and longer stretches of wilderness. This is the float for people who want a real adventure — pack snacks and plenty of water.
Different outfitters offer different put-in and take-out points, so the exact sections and float times vary. Ask about which sections have the best rapids, the deepest swimming holes, and the most scenic views — each outfitter knows their stretch of river best. Curious how long other rivers take?

Outfitters
The Guadalupe River has some of the most established outfitters in Texas — some have been running tubing trips since the 1970s. Pricing is straightforward: $20–$25 for a tube rental, plus shuttle service on longer floats. Most outfitters are located along River Road between Canyon Lake and New Braunfels.
| Outfitter | Price | What's Included | Sections Offered | Notes |
|---|---|---|---|---|
| Tube Haus | $20–$25 | Tube rental, shuttle | Horseshoe Loop + longer floats | Since 1978 — the original |
| Whitewater Sports | $20–$25 | Tube rental, shuttle | Multiple sections | Camping available |
| River Sports Tubes | $20–$25 | Tube rental, shuttle | Horseshoe Loop + extended | Walk-up friendly |
| Rockin' R River Rides | $20–$30 | Tube rental, shuttle | Guadalupe + Comal options | 5 locations across both rivers |

Camping on the Guadalupe
This is the Guadalupe's biggest differentiator. While the San Marcos and Comal are day-trip rivers, the Guadalupe is a camping destination. Several outfitters offer riverside campsites, and there are additional campgrounds along River Road. The typical weekend plan:
- •Friday evening: Drive down from Austin (~1 hour). Set up camp. Grill dinner by the river. Stargaze — it's dark out here.
- •Saturday: Float the river all day. Horseshoe Loop laps, longer floats, swimming holes. Cook out at camp that evening.
- •Sunday morning: One more lazy float before packing up and heading home.
Camping options range from primitive tent sites ($15–$25/night) to cabins with AC ($100+/night). Most campsites include river access and tube rentals. Book early for summer weekends — popular sites fill up weeks in advance, especially around Memorial Day, July 4th, and Labor Day.
What to bring for camping + tubing: everything on our standard packing list, plus a tent, sleeping bag, camp chairs, headlamp, firewood (available at most campsites), and a portable grill or camp stove. Bug spray is essential — mosquitoes come out at dusk. Planning a group camping trip? Check out our guides for bachelor party float trips and corporate team outings.
Rules & Conditions
The Guadalupe has some unique considerations compared to the other rivers:
- •Dam-controlled flow. Check the USGS gauge before going. Flow below 50 CFS means shallow, slow floating. Flow above 300 CFS means fast current — experienced tubers only. The sweet spot is 100–200 CFS.
- •No glass. Prohibited everywhere on the river.
- •No styrofoam. Banned on all rivers near Austin.
- •Cans generally allowed. Outside of New Braunfels city limits (which covers most of the Guadalupe tubing area), cans are permitted. But check with your outfitter.
- •Life jackets under 13. Texas state law — required for all children under 13.
- •Respect the land. Much of the riverbank is private property. Don't trespass, don't leave trash, and pack out everything you bring in.
