Crystal-clear, spring-fed water over a white limestone bed — gentle pools through Wimberley and the town of Blanco, and one of the easiest rivers in the Hill Country to spend a slow afternoon on.
About the river
The Blanco gets its name from the Spanish for "white" — the pale limestone bed gives the water its bright, clear color. It's spring-fed and shallow for much of its 87 miles, running east through the town of Blanco and Wimberley before it joins the San Marcos. Blanco State Park puts an easy, shaded stretch within reach in town, with calm pools for swimming and fishing. It's a quieter, family-friendly river — but a flashy one, so the live gauge above is the honest answer to "how's the water this weekend."

Common questions
Check the live USGS gauge at the top of this page (station 08171000, the Blanco at Wimberley). The Blanco is spring-fed and usually runs clear and shallow, but it's a flashy river — low, calm flow means a gentle float, and a sharp jump means high, fast, muddy water. When the gauge spikes after rain, stay off it.
Yes — it's one of the gentler Hill Country rivers, with calm, clear pools that are good for swimming, wading, and a slow afternoon. Blanco State Park in the town of Blanco has easy, well-kept access. Just respect the water: the Blanco can rise fast, so check the gauge and the forecast before you go.
It rises from springs in Kendall County and runs east about 87 miles through the town of Blanco and Wimberley before joining the San Marcos River. The two easiest places to know are Blanco State Park (in Blanco) and the crossings around Wimberley.
Wimberley is the best base on the river. Vacation rentals near Wimberley are managed by Backroads Hill Country, in business since 2001. Browse current availability through Backroads.
Yes — like most Hill Country rivers, the Blanco is prone to flash flooding, and it can rise from a calm stream to a dangerous torrent in minutes after heavy rain upstream. The 2015 Memorial Day flood at Wimberley is the hard reminder. Always check the live gauge and the weather, and never enter high or fast water.
Late spring through summer, when spring flow keeps the pools full and the water's warm enough to swim. Fall is quieter with lower water and easier rental availability — just know that low spring-fed flow can leave some stretches shallow.
Good to know
The Blanco runs clear over a white limestone bed, low and gentle much of the year, with good swimming around Wimberley and Blanco State Park when it’s up. It’s a flashy river, though — the same canyon that makes it pretty sends it up fast after heavy rain, as the 2015 flood showed. The live gauge above is the honest answer to how it’s running. Glass is a bad idea anywhere near the water, there are no lifeguards, and low-water crossings flood first — check the level, then go.
