Waterloo Mountain rises steeply above Waterloo Lake and the Musconetcong River. The true summit is a small, viewless cone, but there are cliffs which offer expansive views to the south and east.
Waterloo Mountain is well-covered by the Pebble Trail (marked yellow). In conjunction with the 517-Waterloo Trail, the Pebble circles Waterloo mountain, passing by some views and a gigantic glacial erratic. The true summit is off trail, near the Pebble Trail/Highlands Trail junction.
From the picture, the viewpoint along the Highlands Trail, just below the Eastern summit bump.
I was on the trail by 545, but I went a mile in the wrong direction and had to back track :) oops!
By the time I got to the overlook, the sun was shining. Bushwhacked to the summit and took an unmarked trail off the yellow back to the parking lot. Because of my detour and work schedule, I had to "ditch" the Cardiac trail and save Allamuchy Mountain for another day.
LOVE this trail, especially the view off the Highlands. It may not be a very big mountain, but the view is beautiful and we took many pictures. Then you continue on up to the yellow and bushwhack to the peak. There was an old shoe nailed to a tree, still wondering about that one! This was our third day peakbagging in a row which is a far cry from our usual 1-2 a month.
