Parked at the Waterloo Village parking lot and crossed the street to the Highlands Trail since the trail head had not been plowed. Took the Highlands Trail up as close as I could get to the summit and then bushwhacked the final few hundred feet.
From Waterloo Mtn. I took the Highlands Trail down to the intersection with the White Trail. I took this until I got to an intersection with some posted signs. Followed an unmarked trail along the posted sign boundary until I got to the summit. I think the actual summit is within the posted signs so I took the large boulder to be the summit as it was close enough.
From Allamuchy Mtn. North, took a few unmarked trails from the summit that went down to a swampy area. Following some unmarked trails I eventually intersected with the purple Cardiac Trail. I took this all the way up until I got close to the summit and then bushwhacked the final stretch to the highest point.
