I am confused about the elevation gain for this hike as my altimeter often gave faulty reading on this trail. I believe the net elevation gain should be around 1000-1200 ft, however the cumulative gain could be in excess of 1600 ft. At around 5 miles into the hike, you reach the Loowit trail junction and the trail continues in both directions (left and right) to possibly circle the mountain upto Windy Ridge (to the right).
Mt Adams upclose from the Ape Canyon. It takes around 90-120 mins (times may vary) to cover the distance. I won’t recommend this as a day hike, only if you want a decent trail to mountain bike.
