Central Pennsylvania Appalachian Trail Nice hike on the Appalachian Trail, to reach the top of Peters mountain. The trail starts just past the railroad tracks and is a somewhat steep climb up. As you skirt the side of the mountain on the way up, you will have wonderful views of the Susquehanna river below. Once you get so far up, the trail will start to flatten out. As you near the edge of the mountain, the trail again starts to get steep. You will encounter a few switchbacks and vistas as you near the summit. The trail continues north on the mountain top from here. As always look for the white blazes.
