Trough Creek State Park is the county's best small hike and a favorite among photographers. Tucked into a narrow gorge in the Allegheny ridges near Raystown Lake, the park packs a surprising number of features into a short loop: Rainbow Falls tumbling over a rock face, Balanced Rock perched on a ledge, a long suspension bridge across the creek, and a natural ice mine where cold air from the rocks has formed ice into summer. The trails are short and well marked, with stone steps and boardwalks in places, so most visitors can see the highlights in a couple of hours. The park has been protected for generations, and its mix of hardwood forest, hemlock shade and clear mountain stream gives it an atmosphere distinct from the open lake. Spring brings high water and wildflowers, summer offers cool shade, autumn paints the gorge in color, and winter freezes the falls into sculpture. Picnic areas and a modest campground make it possible to stay longer, and the park is a gentle introduction to Pennsylvania state parks for first-time visitors.
Most visitors begin with the Rainbow Falls trail, a short walk to a cascade that catches the light, then continue to the suspension bridge, which is the park's signature photo. Balanced Rock sits on a short climb above the creek and rewards the effort with a view over the gorge, and the ice mine is a point of curiosity rather than a long hike.
The terrain is moderate, but rocks and steps can be slick, so wear shoes with grip, particularly after rain or in freeze and thaw seasons. Trails can be busy on fall weekends, so arrive early to find parking and enjoy quieter paths.
Trough Creek makes an excellent complement to the lake. After a morning on the water or the bike trails, the park offers a shady, restful afternoon. It also suits families with older children who can manage steps and uneven ground, though small children need supervision near ledges and the suspension bridge. Dogs are generally allowed on leashes in state parks, but check posted rules. Bring water, a camera and a snack, and consider a picnic by the creek.
Seasonal conditions matter. Ice and snow can close or hazardously coat sections of trail in winter, and heavy rain can raise the creek and make crossings unpleasant. Check conditions with the park or the visitors bureau before you drive, since cell coverage in the gorge is limited. A visit fits easily into a day that also includes Lincoln Caverns, the Swigart museum or a train ride, and in October it ranks among the prettiest short walks in central Pennsylvania.
