This is really one of the best sections of trail to hike. There are multiple scenic overlooks. There's a boulder field, a reservoir, plenty of access to water, and multiple campsites.
If you choose do this section going North to South, be careful around the boulder field. The trail does turn left in that area and it's possible to miss the turn if you're paying attention to the rocks and not the trail markers.
It's quite an uphill hike to get out of Hertlein campsite when heading towards Rt 183.
It's easy to extend this trip a few miles by going from Rt 183 to Rt 645.
