Nestled in the Allegheny Plateau, Twin Falls Resort State Park offers many hiking trails. The popular Falls Trail is surrounded by densely forested mountains, and travels to the high volume cascades of Marsh Fork Falls and Black Fork Falls. Part of the trail travels over a century old logging road, which was the old entrance into the park. There are towering maple and hemlock along the trail canopy with mountain laurels and rhododendron in the understory. The waterfalls are at their highest volume during spring.
