Good for exercise but not for nature sightings. Not too busy but little shade so it was very hot. Recommend bringing water for the full loop.
It was nice. Very nice hike.
Actually ended up hiking two other trails in the Valley Forge park! Aside from some slight inclines, it was fairly easy. Lovely views of some historic sites, and very pretty wooded areas. The only downside is that in a lot of areas, you are hiking close to semi-busy roads, which creates noise pollution and takes away from the views. Overall, nice weekend day hike!
One other problem is that the maps of non-paved trails (essentially, trails that aren't the Joseph Plumb Trail) are pretty unclear and certain trails are unmarked. We used this person's guide http://gonehikin.blogspot.com/2011/02/valley-forge-national-historical-park.html and the description of the route was very clear and easy to follow!
The trail that is mapped here is just the paved loop around the main area of the park. The photos that are linked to this site can be misleading... there are many options in sidetrails to choose but the actual Joseph Plumb Martin Trail is paved. As a biker, I did half trail, half paved. There are a lot of walkers/joggers. If you want speed, please don't zoom past the walkers using this trail; stick to the roads and watch for the cars.
