The Blanco River

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.

Source: USGS Water Services. The Blanco is a flashy river — it runs clear and shallow most of the time, then comes up fast after rain upstream. These are live readings, not a safety rating — levels change fast and vary stretch to stretch, so check in person before you go and never enter high or fast water.

About the river

Clear water, a white limestone bed, and a gentle float.

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

Blanco River, answered.

How is the Blanco River running right now?

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.

Is the Blanco River good for swimming and families?

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.

Where is the Blanco River in the Hill Country?

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.

Where should I stay on the Blanco River?

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.

Is the Blanco River prone to flooding?

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.

When is the best time to visit the Blanco?

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

Read the water before you go.

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.

Respect This Place — Texas Hill Country The River Code Read the code

Built with the locals who know these rivers best. The Frio and the Guadalupe show what happens when a river gets loved too hard — these are the few things that keep the rest the way they are.

  1. Pack out everything you bring in. Bottles, cans, butts, bait tubs — all of it. Bring an extra bag and grab what someone else left.
  2. No glass near the water. Broken glass in a swimming hole ends a perfect day in the ER. Cans and plastic only.
  3. Know where you're allowed to be. Most of this is private land. Stick to public crossings, parks, and posted access.
  4. Park with respect. Not on the crossings, the bridge, or in front of a ranch gate.
  5. Respect the water. Check the gauge; never cross a flooded crossing — on foot or in a truck.
  6. Leave the rocks where they lie. Stacked-rock towers wreck fish habitat. Let the riverbed be a riverbed.
  7. Don't drive in the riverbed. Trucks and ATVs crush the gravel beds and everything living in them. Park up top and walk down.
  8. Leave the wildlife alone. Don't feed it, chase it, or take it home — fish and turtles included.
  9. Keep it quiet, keep it dark. Skip the speaker. Leave the next person the water sounds and the stars.
  10. Mind fire and burn bans. Summers run dry and bans are common. Check before you light anything, and never leave a coal smoking.
  11. Leash 'em and clean up after 'em. Keep dogs close on shared water and private land, pick up after them every time, and don't let them chase wildlife or disturb other visitors.
  12. Spend your money in the river towns. Gas, food, supplies — the small towns are what keep these rivers accessible. Keep them alive.
