The Summer / Fall season are reported to be the best time to hike the Mt. Forgotten & Perry Creek Trail (# 711). To get to the trail head, go east on Mountain Loop Highway 15.2 miles from the Verlot Public Service Center (11 miles east of Granite Falls). Look for Perry Creek Road #4063 on the left. Follow that road for 1 mile, which will end at the trail head.
The trail begins with a gradual climb, and continues this way through forest and open talus slopes, where an abundance of ferns can be found. The trail will eventually take you to Perry Creek Falls. Along the way there are views of a number of waterfalls on the other side of the valley, that are said to be "spectacular". 1.9 miles into the hike is where the Perry Creek Falls are located. Look for places to rest and have lunch. Up on the hil nearby above the falls is a backcountry toilet.
The trail will continue 1.7 miles to a meadow (the first of more than 1), where more great views can be found. After the trail crosses through the meadows, you'll come to an area where climbing Mt. Forgotten begins. The climb itself is reported to be for experienced mountain climbers. Mt. Forgotton stands at an elevation of 6005 feet, offering great views of Mt. Baker to the north, and Glacier Peak to the east, and then Mt. Raineir to the south.
