While there is a lot to love about San Marcos (and we mean A LOT) exploring the crystal-clear San Marcos River is always at the top of the list. The spring-fed river stays 72-degrees year-round, perfect for adventures whenever strikes your fancy. Whether you're looking for a calm and peaceful paddle or adrenaline-fuelled white water run down the falls, you're in for a great SMTXperience.
About The River
The San Marcos River bubbles to life right in the middle of town at The Meadows Center. The Edwards Aquifer comes up through more than two hundred springs in the lakebed. The water then flows from Spring Lake and through San Marcos before joining forces with the Guadalupe River and flowing into the Gulf of Mexico. The San Marcos River is home to seven endangered species, including the San Marcos Salamander and Texas Blind Salamander. A unique, and endangered, feature of the San Marcos River is the Texas Wild Rice, which grows solely within about a mile and a half range of the San Marcos River. The long underwater grass helps clean pollutants out of the water, which we certainly appreciate.
While there's no wrong time to enjoy the San Marcos River, paddlers can enjoy the river all to themselves when tubing season isn't in session. Or, head out for a morning paddle in the summer when most folks don't start showing up to the parks until it starts to get a little hotter. (7-10 am is usually a good window)
If you're looking for a peaceful, easy paddle, head to the upper San Marcos River that flows through town and avoid the rapids at Rio Vista Park. If you're in for a more rugged paddle, the lower San Marcos River may be more your scene with its stronger currents and murkier waters that make for excellent fishing if you're interested. And, adrenaline junkies with an interest in white water kayaking will love the Rio Vista Falls in the off-season.
- San Marcos is full of natural beauty and we really want to keep it that way - take what you bring and dispose of trash properly
- Remember, it's a real river! You're going to want to bring along life vests.
- S-U-N-S-C-R-E-E-N, seriously
- Stay hydrated! Bring plenty of water as fun in the sun can be quite dehydrating
- Leave glass and styrofoam at home
- Wear shoes that are strapped firmly to your feet
- Don't bring anything to the river that you don't mind losing
- Stick to public access points
- The San Marcos River does not go in a circle...
