Description: Pounds Hollow Recreation Area is a popular destination for wildflower enthusiasts, hikers, picnickers, and folks who enjoy swimming and relaxing on a beach. There are two interesting trails that traverse the area allowing visitors to experience a wide variety of natural communities and marvelous geological settings, such as sandstone glades and cliffs, and a sandstone canyon with a gentle stream flowing through the canyon and into Pounds Hollow Lake. Rim Rock National Recreation Trail has a separate parking lot just west of the entrance to Pounds Hollow Recreation Area. From Rim Rock trail visitors can descend the tall cliff face by means of a staircase that takes you through a narrow pathway between giant sandstone cliffs. Natural communities include sandstone glades; sandstone cliffs; xeric, dry, dry-mesic, and mesic upland forests.
Viewing Information: Throughout the year numerous wildflowers can be seen throughout this beautiful area. Wildflowers in the sandstone glades and xeric forests include common blue violet (Viola sororia), small bluets (Houstonia crassifolia), dwarf dandelion (Krigia virginica), pussy-toes (Antennaria plantaginifolia), violet wood-sorrel (Oxalis violacea), false garlic (Nothoscordum bivalve), glade wild petunia (Ruellia humilis), prickly pear (Opuntia humifusa), yellow star grass (Hypoxis hirsuta), widow’s cross (Sedum pulchellum), goat’s rue (Tephrosia virginiana), rough buttonweed (Dioidea teres), and rushfoil (Crotonopsis elliptica).

Wildflowers commonly encountered include Indian physic (Gillenia trifoliata), dittany (Cunila origanoides), St. Andrew’s cross (Hypericum hypericoides), Beebalm (Monarda bradburiana), mayapple (Podophyllum peltatum), bloodroot (Sanguinaria canadensis), Virginia spiderwort (Tradescantia virginiana), and hog peanut (Amphicarpa bracteata).

Safety First: Be prepared in spring, summer and autumn for rapid changes in weather as thunderstorms may develop rapidly. Timber rattlesnakes and copperheads may occasionally be present so please stay alert. None of these snakes tend to be aggressive but they will defend themselves if stepped on or threatened at close range. Just watch the ground as you walk and you should not have any problems. Be aware of pedestrians in the parking areas. Summer temperatures can be high, 90 to 100 F but are generally less in the mesic forests and canyon floor along the creeks. Bring plenty of bottled water as creek water is not suitable for drinking. Wear appropriate clothing for the outdoors. Be sure to bring sunscreen and insect repellant. Wood ticks are always present, except for winter months. Be sure to check yourself out for ticks after you visit. Poison ivy is common; remember, "Leaves of three let it be!"
