May 9, 2026 15 min read Both rivers come from the same source — the Edwards Aquifer — and both run a steady 72°F year-round. So why does it matter which one you tube? Because the experience is wildly different. Here's the honest, side-by-side comparison from people who run a property on one of them: [Son's Blue River Camp](/) on the San Marcos. ## The Quick Answer Comal River: shorter, more chutes, much more crowded, party-leaning, in-town. San Marcos River (at Son's): longer, gentler, private, family-leaning, country. If you're 22 and your group has matching tank tops, go to the Comal. If you have kids or you want to actually relax, drive east to the San Marcos. ![Family tubing the San Marcos River](/assets/family-tubing-DDGklnV2.webp) ## Water Temperature Tie. Both are spring-fed at the headwaters and run roughly 70–72°F all year. The Comal is technically a touch warmer in summer because it's so short, the San Marcos picks up sun further downstream. In a tube you cannot tell the difference. ## Crowds San Marcos at Son's wins by a mile. The Comal in July averages 3,000–5,000 tubers a day across the public outfitters. The Tube Chute is famously a 30-minute wait. The San Marcos at Son's runs through a private 8-acre property with capacity capped daily — it feels like a friend's ranch, not a theme park. ## Float Length Comal floats are 2–3 hours including the chute. San Marcos floats at Son's are roughly 90 minutes river-time per lap, but the wristband includes unlimited re-floats with shuttle. Most groups float twice in a day — second lap with snacks and a slower pace. ## Vibe Comal: bachelorette parties, college groups, can-jammers. Music is loud, people are loud, you are loud. Great if that's the trip you're planning. San Marcos at Son's: families, multi-generational groups, friends who want a riverfront cabin. Quiet hours are real. Music is allowed but not loudspeaker territory. ## Float the San Marcos at Son's Spring-fed, private, family-friendly. Twenty minutes east of New Braunfels. [Day Pass](/day-rentals)[Book Cabin](/book-now/blue-river-camp-overnight) ## Drive Time From Austin: Comal 60 min, San Marcos at Son's 60 min. Tie. From San Antonio: Comal 35 min, San Marcos at Son's 50 min — Comal closer. From Houston: both about 3 hours. From Dallas: both about 3.5 hours. ## Where to Stay This is where the San Marcos pulls ahead. Comal lodging is hotels and Airbnbs in town — none of them on the river. San Marcos at Son's has riverfront [log cabins](/log-cabins), [glamping cabins](/glamping), and [tent sites](/tent-camping) at the put-in. You wake up, walk out, you're floating. ![Friend group tubing the San Marcos](/assets/gallery-friends-group-tubes-DLyeZvMa.webp)![River beach on the San Marcos](/assets/river-beach-property-DimfzXs_.webp) ## Pricing Comal outfitter tubes run $20–25 per person plus parking ($10–20). San Marcos at Son's is $29.99 unlimited with shuttle, parking included. If you float twice, Son's is cheaper. If you float once and leave, Comal is cheaper. ## Kids San Marcos wins. The Comal's tube chute is a 4-foot drop that scares some kids and isn't safe for little ones — most outfitters route them around. The San Marcos at Son's has no chute, gentle current, and shaded river beaches every few hundred yards for breaks. ## Cooler Tubes & Glass Both rivers ban glass. Both allow cooler tubes. The Comal Bandit-style chute can dump coolers in the rapid; the San Marcos has no chute so coolers stay in. ## Cleanliness The Comal is famously clean for a public tubing river — locals are passionate about Litter Patrol. But sheer volume means cans, cups, and lost goggles. The San Marcos at Son's, being private, gets daily property cleanups and feels pristine. ## When to Choose Each **Pick the Comal if:** you're young and want a party, you want walk-around bars in New Braunfels after, or you're doing a one-hour quick float. **Pick the San Marcos at Son's if:** you have kids, you want to camp/cabin overnight, you hate crowds, or you want unlimited floats in one day. ![Family on the San Marcos River vs Comal](/assets/testimonial-5-BgRoNc9X.webp) ## FAQ ### Can I do both in one weekend? Yes. Float the Comal Saturday morning, drive 20 minutes east, sleep at Son's, float the San Marcos Sunday. Best of both. ### Which is better in October? San Marcos. Comal outfitters scale back; Son's runs floats year-round. ### Are dogs allowed? San Marcos at Son's: yes, on shore (no tubing). Comal: outfitter-dependent. ## Tube the Quieter River Same spring water, half the crowd, twenty minutes east of New Braunfels.
