The Birch Trail is an isolated hike located deep in the Tioga State Forest, near Leetonia. It features a narrow ridge with views and many unique rock formations. The drive to it along Cedar Run is beautiful, with gorges and waterfalls. Cedar Run is a well-known trout stream with many pools, slides, and grottos. I began at the parking area in Gleason Hollow, it is pull off parking, and there is a beautiful bedrock pool in Cedar Run nearby. Cross the road and begin on the Birch Trail, where there is a sign.
The trail is blazed red and soon makes a steep climb up the ridge under pine trees. Leave the pine trees and reach the narrow ridge, where rock outcrops begin to appear. Scramble up some ledges and reach a scenic double vista off both sides of the ridge. Mountains and gorges surround you. Continue to follow the ridge with a moderate climb. The red blazes become more infrequent, but there is generally a path to follow. The narrow ridge is very unique, with many interesting rock outcrops and formations. There are columns of rock, and one formation that resembles a mushroom. The trail sign near the parking area calls these the “Chimney Rocks”. The ridge is often composed of ledges. Enjoy two views off the left, of west, side of the ridge. Climb up the ridge and reach the plateau, and a deer fence.
The trail crosses through the fence and becomes more overgrown with briars. The blazes are still there, but infrequent. This may be tough to follow in the summer. Climb gradually and reach the end of a forest road. Follow the road as it descends. Again, blazes along the road are infrequent. The trail makes a discreet turn to the left, it is easy to miss. Descend into Callahan Hollow and pick up an old grade. The trail curves into a scenic pine forest and descends to Cedar Run. There is no bridge across Cedar Run, so expect wet feet. There was a fallen tree a hundred feet or so upstream that you can cross.
The Birch Trail enters a beautiful spruce forest with moss. Climb up to Leetonia Road and another trail sign. Turn left and walk the road back to complete the loop.
This description follows the loop counterclockwise. While the ridge is the most scenic part of the hike, I enjoyed the entire loop. The loop is about four miles long.
Pull off parking is at 41.579730, -77.473997.

Thanks for the write-up! Prompted me to include it in a BFT/WRT backpacking loop, and we seriously enjoyed it. Getting to it from the WRT (at West Rim Rd) uses a confusing bunch of logging roads but is doable.
