Trees such as Ashe juniper, pecan and bald cypress cover the hilly terrain along the river. Wildflowers bloom seasonally. Look for bluebonnet, Engelmann daisy, Texas paintbrush, firewheel, greenthread and four-nerve daisy.
Wildlife in the park
Watch for wildlife while you’re here. Great blue herons perch atop the CCC dams, waiting patiently before diving into the water to catch a fish. Red-eared sliders, spiny soft shell turtles and river cooters bask on logs along the river. Look for common musk turtles (not as common as the name suggests!) at the bottom of small pools. You may also see green herons, squirrels, cricket frogs, Gulf coast toads and leopard frogs.
Springs from the Trinity Aquifer feed the Blanco River, which begins in northeast Kendall County.
The river’s name comes from its white limestone ledges and river bottom. The limestone here dates back to the age of the dinosaurs.
The river flows about 87 miles southeast through Blanco and Hays counties, before joining the San Marcos River in San Marcos. It is mostly shallow, except above low water dams like the two dams in the park.
