As this is a central Texas site where it is often windy and very hot in summer, sunscreen and plenty of water, as well as frequent breaks should be taken in summer, and patience had while birding. Birds of Central Texas are at the periphery of their respective ranges, and in this more arid, environment, birds are often found in smaller numbers. A good starting point is the bird blind which is just past the road to the youth camp area on your left off the main park road. At any season birds native to the area may wander in or forage around, and it may be a good way to see birds that otherwise might be difficult to find on the trails. Then at the very end of the main park road is a trail that leads to the falls. This is probably one of the best short trails to see the regionally endemic Golden-cheeked Warbler. At the end of the trail at the Pedernales River, the Cliffs on the adjacent side, especially when it isn't busy often hold Canyon Wren, and a Rufous-crowned Sparrow might be foraging nearby as well on the near shore. The Twin Falls trail is the next place to look for a number of birds, especially in summer when the shaded area may attract Eastern as well as western birds like Great-crested Flycatcher, Louisiana Waterthrush,  Canyon Wren, Vermillion Flycatcher, and possibly Green Kingfisher. For the more in shape, adventurous, and well-prepared there are longer trails as well as a fire road(which may not be open to the public) that can be traversed where you may luck upon one of the park's rarer residents like Bushtit or Canyon Towhee. Many of the western residents are year-round, but the list of possibilities in winter and migration in this transitional zone between east, west, and south is staggering. During these times especially check the skies and the bird blind. You may see very little,  but the likelihood of seeing something interesting will increase with time in the field.

This is a transition zone between East and West, so most Eastern birders will be keen to find the more westerly birds, however during the period from mid-March to July this park is home to Texas' only breeding endemic,  the Golden-cheeked Warbler, which is found in areas of the park with mature Ashe Juniper woodland.   Other birds of interest that reach their Eastern limit in the hill country of Central Texas are Black-chinned Hummingbirds, Golden-fronted and Ladder-backed Woodpeckers, Ash-throated Flycatchers, Woodhouse's Scrub-Jays, Canyon and Bewick's Wrens, Lesser Goldfinches (beautiful black-backed 'Texas' race), and Rufous-crowned Sparrows. In addition, it is a great place to connect with the unfathomably beautiful Painted Bunting, which loves the more open short Juniper and scrub oak as well as weedy areas of the park. Winter may bring siskin as well as a number of sparrows including Spotted Towhee. In migration and winter rarities recorded include Common Black-Hawk, Ringed Kingfisher,  Green-tailed Towhee, Black-throated Gray Warbler, and Lazuli Bunting.

Pedernales Falls State Park covers 5,212 acres of scenic Hill Country terrain. The park's main attraction is the Pedernales River, which flows over and around huge slabs of limestone, creating waterfalls, pools, and rapids. Visitors can swim, wade, tube, fish, or paddle on the river, but they should be aware of the potential for flash floods and avoid the Pedernales Falls area, which is off-limits for water activities. The park offers camping, hiking, biking, horseback riding, geocaching, and wildlife viewing opportunities. The park has a variety of trails that range from easy to challenging, including the Wolf Mountain Trail, which circles around two mountains and passes by a natural pool called Arrowhead Pool. The park also has a bird blind and a butterfly garden. 

The park is open for day use 8 a.m. to 10 p.m. There is ample camping, both primitive and developed, and visitors arriving after 10 p.m., will have to call the office to obtain the gate code. It is a well-developed park with many activities, like swimming, and a few amenities like restrooms. Pedernales Falls is located near the eastern end of the Edward's Plateau a unique transition zone between East and West, where many birds are of Eastern or Central distribution, but several birds are found more commonly to the west, as well as some endemic or nearly endemic to the region are found. 

The short, but steep Twin Falls and River trail to the Pedernales Falls are great trails for a diversity of birds. Longer trails exist, but may at times be birdless and water and sunscreen are strongly advised.
