Pedernales Falls is located 30 miles West of Austin and only a quarter mile walk from the parking lot. You can head a little further down river if you're looking to take a dip.
Pedernales Falls drops 50 feet in elevation over 3,000 feet of titled, layered steps of limestone along the Pedernales River in Blanco County. In order to reach the falls you must enter Pedernales Falls State Park and follow the park road until the very end. There you'll find a parking lot and it's only about a quarter of a mile walk to the falls. If you want to do a bit more exploring of the area, I suggest wearing hiking shoes because it's rocky, slippery, and some places are covered with shrubs. If you're looking to just relax, there is a small beach area where you can set out your towel, bring a cooler, and soak up some rays.
