I’ve taken a bunch of newbies on the Old Loggers Path – I think I’ve hiked that loop 6 times. The direction in which you hike it depends on the time of day you’re starting. Starting from Masten you should hike it clockwise if you’re starting in the morning…That puts both of your campsites at nice watering holes (11-10-6 miles by day. If you’re starting in the afternoon, go counter-clockwise to stay at the same sites (6-10-11). PM me for more details about the OLP if you’d like.
My current newbie favorite loop in PA is the Pinchot Trail (near Thornhurst PA) on the Pocono Plateau. It doesn’t have the elevation gain/loss of the OLP so it’s a bit less strenuous. It’s also close to a “figure-8” trail so you have the easy option to bail halfway through if the weather turns nasty or you have other issues. You always want the first trip to be successful.
Another quick PA loop is the John P Saylor trail near Windber PA (a bit further west). Not a lot of elevation gain/loss and some cool rocks (Wolf Rocks) to climb on along the trail. Sadly it’s a local graffiti spot, but you can still climb around. There’s also a cool suspension bridge over the creek at the campsite. Again – PM me with questions.
There’s another great 2-night loop just outside State College called the Ironstone-MST loop. It starts/ends in the Shaver’s Creek Environmental area and includes a nice gradual uphill as well as a solid 1/4 mile straight up followed by a great ridge walk. It connects with the Mid State Trail and then comes back to Shaver’s Creek passing an old iron furnace.
I can also make some suggestions for Dolly Sods…Good luck!
