San Marcos is one of Texas’ most iconic river towns, known for crystal-clear, spring-fed water that stays around 72°F year-round. Floating here means relaxed tubing and casual drifts through town.
This guide focuses on the best places to float in San Marcos, highlighting access points, float lengths, and how to enjoy the river responsibly.
Best Time to Float in San Marcos (Seasonal Guide)
Floating the San Marcos River is possible year-round, but conditions, crowds, and overall vibe change with the seasons.
- Late Spring (April–May): Warm Weather, Manageable Crowds - Temperatures rise, the river feels refreshing, and crowds are lighter than peak summer. This is a great time for longer floats and laid-back river days without heavy congestion.
- Summer (June–August): Peak Floating Season - Summer brings the most energy, tubing traffic, and social atmosphere. Expect busier access points, especially on weekends, but also the full San Marcos floating experience locals love.
- Early Fall (September–October): Calm and Comfortable - Cooler air temperatures combine with warm water, making fall ideal for relaxed floats. Crowds thin out, and the riverbanks offer more space to stop and chill.
- Winter (November–March): Quiet but Refreshing - While fewer people float in winter, the steady spring temperature makes it doable on sunny days. This season suits short floats and peaceful river walks more than extended tubing trips.
Top 5 Places to Float in San Marcos
The following locations highlight the most popular places to float in San Marcos, ranging from short town drifts to longer, outfitter-supported routes.
San Marcos City Park — Classic Town Float Start
San Marcos City Park is the most recognizable starting point for floating in town. Multiple access spots make it easy to enter the river, and the surrounding scenery blends natural beauty with a lively local atmosphere.
Most floats from City Park end at Rio Vista Park, creating a smooth, beginner-friendly route. Depending on river flow and entry point, the float typically lasts 45 to 60 minutes, making it ideal for casual outings.

Key things to know about floating from City Park include:
- Central location with easy walk-in river access
- Popular starting point for self-guided floats
- Close to local rentals and parking areas
- Clear signage for river rules and exits
City regulations are strictly enforced to protect the river. Glass containers, Styrofoam, littering, and jumping from bridges are prohibited.
For slower moments along calm banks, we like relaxing on stable floats such as the iLAND® 8', which works well when you want to pause and soak up the scenery.
Rio Vista Park — Popular Float Exit & Chill Spot
Rio Vista Park is the main exit point for floats starting upstream, especially from City Park. It’s more than just a take-out location, it’s a social hub where floaters regroup and relax.
The park offers various amenities that make it easy to extend your river day. Restrooms, picnic tables, courts, and nearby trails allow you to transition seamlessly from water to land.

Highlights of Rio Vista Park include:
- Designated exit areas for tubers
- Open green spaces for drying off and resting
- Shaded picnic zones ideal for groups
- Calm sections to tie floats together
This spot is perfect for connecting multiple tubes, especially with something spacious like the iLAND® by iROCKER 6' Round Float.
Since river rules ban Styrofoam and disposable containers, securing essentials in a MAG Pocket waterproof pouch helps protect phones, keys, and IDs while staying compliant.
Veramendi Plaza River Spot — Scenic Float Locale
Veramendi Plaza offers a quieter alternative for those looking to enjoy the river without peak crowds. Located along a scenic stretch, it works well for shorter floats or mid-route breaks.
This area is popular for weekday floats and shaded rest stops between drifts. You can enter from nearby access points like Lions Club or float down from longer upstream routes (Don’s Fish Camp).
What makes Veramendi Plaza appealing:
- Less foot traffic compared to central parks
- Tree-lined banks with natural shade
- Flexible access for partial floats
- Calm water ideal for stopping and relaxing
As with all San Marcos river locations, rules prohibit glass, Styrofoam, littering, and jumping from structures. We often bring the iLAND® Hopper Chair here to relax comfortably at the river’s edge before hopping back in.
Don’s Fish Camp Float Section — Longer Float Route
For those wanting a more immersive river experience, Don’s Fish Camp offers one of the longest float routes on the San Marcos River. This section is ideal for groups and full-day outings.
The float can last up to 3 hours, depending on conditions. Shuttle service and designated parking make logistics easier, especially if you’re bringing your own gear.

Why floaters choose Don’s Fish Camp:
- Extended float time with steady current
- Shuttle service simplifies transportation
- Popular with groups and weekend trips
- Open river scenery with fewer urban sections
Longer floats mean more time to relax, so accessories matter. Using an iLAND® Bar Table with Insert helps keep beverages secure and accessible without disrupting the flow of your float.
Texas State Tubes — Extended Float Adventure
Texas State Tubes is one of the most well-known tubing outfitters in the area, offering structured long-route floats.
Their routes typically last around 3 hours and include shuttle service, making them a convenient option for visitors unfamiliar with local access points.
What to expect with Texas State Tubes:
- Clearly marked routes and exits
- Transportation included
- Consistent float length and pace
- Popular choice for first-time visitors
Staying hydrated is essential during extended floats. Bringing reusable drinkware like the iROCKER MAG Cup 20oz keeps water cold and easy to access throughout the trip.
