Starting Location: Park at P15. Follow the wide trail from the parking lot about 100 m to the right of the building. You will pass the access to the McCumber Brook Wetlands on your right. Continue on this trail which will veer to your left. You will eventually come to a narrow pathway and a blue sign that will mark the end of the parkway land and the beginning of the Big Salmon River Protected Natural Area. Follow this pathway 100 m and you will arrive at Walton Glen Gorge. Some call this the ‘Grand Canyon of New Brunswick’, while other think it is much more spectacular. The distance for this trail is measured for one way.
