May 11, 2026 8 min read Kingsbury, TX The San Marcos is one of the only spring-fed rivers in Texas that runs **72° year-round** with crystal-clear water, small rapids, and no dams. Here's exactly how to tube it. ## Step 1 — Pick your launch Two main options: - **Public city launches in San Marcos** (Lions Club Tube Rental, Texas State area). Cheap rental, but parking is a hunt and Saturdays are packed. - **Private launches like [Son's River Ranch](/)** in Kingsbury (45 min from Austin). Walk to the river, private shuttle, no public-launch parking. ## Step 2 — Reserve tubes + shuttle A good rental includes the _tube_, the _shuttle_ back upstream, and _parking_. Stand-alone shops like Texas Canoes & Kayaks or Paddle SMTX bundle some but not all. Our [Ultimate River Fun Wristband](/san-marcos-river-tubing) includes everything — and overnight guests get 25% off. ![Private river shuttle at Son's River Ranch](/assets/gallery-shuttle-area-DvDPF-Ti.webp) ## Step 3 — Pack the right gear - Water shoes (not flip-flops — they float away) - Reef-safe sunscreen - Dry bag for phone + keys - A cooler tube if your group brings snacks - Hat + sunglasses with a strap Full packing list in our [tubing packing list guide](/blog/what-to-bring-tubing-near-austin). ![Flat-lay of tubing gear](/assets/tubing-packing-flatlay-C_y8eB44.webp) ## Step 4 — Float the river The stretch through Kingsbury is family-friendly: gentle current, small rapids, no dams. Pace it slow — most groups take 60-90 minutes per run. Repeat as many times as you want with an unlimited wristband. ## Step 5 — Catch the shuttle back At Son's, the shuttle is **private** and continuous — full breakdown on our [river shuttle page](/river-shuttle). Public launches use shared buses on a schedule. ## Pro tips - **Go on a weekday** if you want a quiet river - **Arrive before 11am** on Saturdays - **Book an overnight** to skip the morning drive entirely - **The river is 72° even in February** — wetsuits exist if you're brave ### Ready to float? Grab a wristband, or add an overnight cabin and your wristbands & other day-rental add-ons are 25% off.
