I parked in the gravel lot at the intersection of Greenwood Lake Turnpike and East Shore Road. I took the sterling ridge trail past the Long Pond Iron Works to the yellow-blazed Jennings Hollow Trail. Heading north along the swampy Jennings Hollow, I left the trail and headed up the northeast side of Jennings Mountain. I eventually came to a rock cairn, different from the one in photos posted by others here. I don't believe this was the summit. I kept heading south and eventually found the the other cairn and summit. Returned the same way I came.
