This is a gorgeous, if not magical forest area. Great for finding the best wood for your wands, or just for exploring a place with a lot of different landscapes. It's both woodsy and fieldy, with thick dense thickets and tall grass. Here's a link to the dec.ny.gov map to give you an idea of the area. CNYHiking also has some good resources to learn more about this area.
Starting at the parking lot on Thomspon Rd follow Trail 1 up the hill for about 3/4ths of a mile. It's a steady, and probably muddy, climb but worth it. The view at the top is spectacular. Continuing on, you'll enter another woodsy area. Take a right at the old tractor and follow the Foot Trail. The Foot Trail is marked with green giscs but also the trees are marked with white and gold spray paint. There's also orange and pink tape in some areas.
GZ is roughly 1.57 miles from the parking lot following this direction. On the way you'll be in range of most of the other cahces in this area, which are worth the find. There's some massive and old trees here. I'm not sure what an American Whomping Tree looks like as I'm only slightly familliar with the British varieties, but judging by the evidence at ground zero, I suspect there was at least one in the area.
