I had never hiked here because the reviews of the trails were not that great and there were not enough trails for me. There used to be a map that was hard to follow because it did not show colors to match up to the blazing of the trails. There is a newer map out now which does show the colors of the trails (although not 100% accurate, it's good enough) and it seems the trails have been reblazed. There are lots of blazes - never had trouble following the trails. There is also another trail that is not on the map that allows for a longer loop hike. On the right side of the map is Pine Run. There is a white rectangle blazed trail that leaves the teal/yellow/white trail and goes down a rocky gorge along Pine Run to meet up with the old rail bed which runs parallel to Musconetcong River. It's slow going picking your way over boulders down this trail but scenic and kind of fun. There are nice seasonal views all along teal/yellow/white ridge trail that will be gone once leaves come back on the trees. Also, the teal Highlands Trail keeps on going beyond Pine Run over to Sweet Hollow Preserve. It involves some road walking but mostly on quiet residential/farm roads with very little traffic so that wasn't bad at all and I was able to get a 10 mile hike out of it without too much backtracking.

A couple of things to note about the map:
