We parked at Burnham Hollow, whacked up Fir, over to Big Indian and then to the trail. Then we hiked the trail to Eagle and whacked directly down from the summit of Eagle to McKinley Hollow where Matt was parked. This was a great hike and avoided the stream crossings and some extra miles. Actually, I would say the worst part of the hike was the part on the trail! Not that it was bad and it is not difficult, but it is not highly used and could use a little maintenance. It is really more that the bushwhacking was great (if you stick to the ridges). So, you may want to consider spotting cars. There is a lot of private land by Burnham Hollow, but if you cross the bridge from the parking area and just start heading right up Fir you'll be okay. If you need West Kill, you could join Matt and I for our finish on Saturday and then do this one on Sunday.
Also, be very careful to stay on the land bridge between Fir and Big Indian. There are some very steep spots and some side hilling if you don't.
