Great park, large well kept serpentine barrens, like going to a different state, completely different from the rest of PA. The trails in the barrens have ZERO shade so I recommend spring and fall. Rolling hills, grasses and a few trees. if you are not familiar I would read up a little one this unique ecosystem before you go, you will appreciate it more.
been here several times to train my dogs for Sar activities. Nice, be carefully in hunting season. I still can't find the horse trails. Picked up alot of ticks in the summer. Nice never seen it crowded. Great place for geocaching.
hope you enjoy, maybe well see you there, if you do you could hide and let my dogs track you down. haha
