Mount Forgotten isn't really forgotten anymore as many hikers take a climbers trail to it's summit each year. But, because of it's location, it is hidden from the Mountain Loop Highway. The upper portion of the mountain is class 3. Many hikers stop at the end of the maintained trail before the scrambling begins, where there are big meadows and great views. Forgotten would be a good "next step" for aspiring mountaineers.

The first 1.8 miles of trail and 1200 gain climbs to Perry Creek Falls. After crossing a log jam, the trail continues in the forest switchbacking up to Stillaguamish Ridge. At 4960 feet is a trail split (easy to miss). Left is Stillaguamish Peak. The trail disappears in places but with some basic route finding, you'll get there easy enough. For Forgotten, go right. Another short trail goes to a campsite. The trail traverses east wrapping around point 5326 to a meadow. From there, you can see the mountain well. This is where many stop. The climbers route drops steeply down toward the saddle between Forgotten and point 5326. Look for the climbers trail traversing the side of Forgotten while you drop. Continue on it as it then traverses around to the northeast side of the summit rocks to a tarn. From there you ascend a gully to the summit rocks. To get to the true summit point, which is about 50 feet west of the east high point, it requires a very exposed 10-foot section of class 4 knife-edge rock.
From Granite Falls follow the Mountain Loop Highway east for 26+ miles, past the Verlot Ranger Station to Perry Creek Campground. From the campground, turn up Forest Road 4063, go left at the fork to the trailhead at the end of the road. A Northwest Forest Pass is required at the trailhead.
