Pedernales Falls State Park is not reached by a main road, although it is just 10 miles from the well travelled US 281 route which begins at San Antonio and travels due north all the way to Wichita Falls near the Oklahoma border. FM 2766 from Johnson City passes the park entrance, from where a short spur road crosses a wooded plateau and descends towards the river, past the obligatory visitor center, picnic area and gift shop. An alternative approach is from the south, along FM 3232. All the surroundings
are lightly settled, consisting of woodland, meadows and occasional fields.
The park is quite large although the river is easily reached at just two places - the viewpoint of the falls themselves and an area downstream. Pedernales Falls are best during the rainy seasons in fall and spring but worth seeing at any time of year. There is one main cascade with several pools and deep channels just upstream, and a large, deep pool beneath. An easy path leads down to the river, at which point wading and swimming are not allowed to protect aquatic life, a rule that seems often not to be obeyed. The underlying rock is porous and some of the water sinks below ground, re-emerging as several clear springs at the edge of the canyon beneath the waterfall.
