The forested areas of the park are largely either on fairly steep slopes, or swampy areas along the floodplain of Wolftrap Creek, with very little moderate slope. There are a few outcroppings of granite along the creek and in the hills. The forest is the oak-hickory forest that is predominant in this area of Virginia. The larger trees on the hills are red oaks, white oaks, chestnut oaks, and mockernut hickories. American holly, redbud, dogwood, and sassafras are common smaller understory trees, and there are some large thickets of mountain laurel on the slopes. In the wetter areas, red maple, ironwood, river birch, tulip poplars, and sycamore are prominent. In wetland areas of the park there is a variety of ferns and large areas of moisture loving skunk cabbage.
