Valley Forge was the site of the 1777-78 winter encampment of the Continental Army. The park commemorates the sacrifices and perseverance of the Revolutionary War generation and honors the ability of citizens to pull together and overcome adversity during extraordinary times.
Very nice trail for trail running. I parked in the Knox Tinder parking lot and ran up Mount Joy out to route 23 and then went up Mount Misery down to Yellow Springs. Steep in spots and easy to stay on course compared to some challenges I had with Misery. Was raining slightly and saw a handful of others including a Boy/Cub scout troop but had a lot of it to myself. Just need to pay attention to rocks while running and one really fast downhill but overall great trail.
It was a very beautiful and scenic trail. The wildflowers are beautiful and smell amazing. I enjoyed watching the birds and butterflies as well! The only down side for me was the portion of the trail right along the road, it was loud and not very peaceful but other than that I loved it!
David R. on Valley Forge National Park Trail
Overall, Valley Forge National Park is great for casual hiking and even some moderately difficult hiking. Some trails are better than others. but that also depends on what you're looking for.
The trails around Mt. Misery are the most strenuous and scenic, followed by the trails on Mt. Joy. Hiking up the Wolfinger Trail is particular steep - great if you want to add some more exercise to your hike. These trails are wooded dirt trails, more akin to your typical sort of hiking trails. These trails also feature some old ruins, a covered bridge, scenic overlooks (especially in fall and winter), and run along side the Valley Creek and other smaller streams at times.
The Joseph Plumb Martin Trail is paved and generally flat with some rolling hills. I wouldn't considering it a hiking trail per se. This trail features several of the the main national monuments such as the National Memorial Arch and the Washington Memorial Chapel, as well as all sorts of Revolutionary War style models of barracks and cannons. The trail loops around a giant open field, which makes for a pretty expansive viewing distance, especially on the north side. The view from the north side of the trail is really nice in the fall when the leaves change colors. Often times you'll see a group of several deer sprinting across this field, which is a cool sight to see.
To me, these trails are the main attractions, but for two different purposes. Mt. Misery and Mt. Joy for more traditional hiking trails. And then the Joseph Plumb Martin Trail more for casual walking, sightseeing, and taking in some good ol' American history.
Of course there are also numerous other trails throughout the park, which are also worth hiking, but they aren't as notable as the aforementioned trails. The River Trail and Chapel Trail, each running on opposite sides of the Schuylkill provide some alternative trails for a change of pace. But these trails aren't quite as scenic, and frankly not as nice as pleasant as the trails alongside the Valley Creek, but they're interesting in their own right.
The entire park is worth exploring though. It's great to visit all times of year.
