If you are going NE, I highly recommend the set of four
Kittatinny Trails maps.
I'll get back to you with some more specifics when I check my maps, but there is parking area off rt. 80 in NJ just before the toll bridge where you can get dropped off. The AT goes up a gully but there is an alternate trail that goes up the knife edge of the ridge that has a nice view.
Then on to Sunfish pond. Yard's Creek Reservoir I think is off-limits due to security. There was a water spigot available to hikers at the camp at Catfish pond. There was an old-fashioned hand pump for water near the trail by Fairview Lake. Then there's Long Pine Pond. Crater lake is more crater than lake. There is supposed to be a spring near the Brink Road shelter. More later...
Note that Fairview Lake Rd. is blocked off at the bottom of "Fiddler's Elbow" (a distinct zigzag switchback) if someone is coming to pick you up there. I grew up about two miles from there.
