Greensfelder is beautiful, so I hate making a semi bad review. BUT the trails are not marked correctly with how many miles it is and the markers for the trails are so confusing it is easy to get lost, which is not the worst of it. The Deer Run Trail is so confusing that my experienced hiking Dad got lost and went an extra 2 miles than the trail said, it got dark and it was to a point where it could have been scary. If elderly hikers wanted to do a short trail and end up getting lost or going an extra 2 miles that could be horrible for them. I think this park needs to rethink their trail markers and make them more clear, and also how many miles they say a trail is.
