Government Camp and Timberline Lodge are not far from Portland. The Glade Trail #661 is one connector between Government Camp and Timberline Lodge by foot, mountain bike or horse. It is part of a complex of trails which is maintained, but not well marked, and many are not mapped. In the Summer, it's rocky and sandy. Some of the trails look like they have minor streams in Spring. In Winter, they could be cross country ski trails. They are kept clear of tree fall, so the snow can build. Some sections are by the original power lines to Timberline, and that is cleared. I have cross country skied down it and it's beautiful. You have to cross some active boarding and ski routes below Timberline to find it. From Government Camp, you can park in Government Camp public areas and walk up the private road to the trailhead. There is very limited parking at the trailhead itself, but only specific dates April-November. There are trail junction signs, but the trails are not very well blazed. I would strongly suggest a printed trail map, a real GPS and survival supplies. Smartphone GPS and Google Maps are not safe to prevent getting lost in the maze of trails! Winter is easier, it can be well traveled and tracked. But prepare nonetheless. I did not make it to Timberline Lodge, #661 and the power line clearing is the absolute shortest route between Government Camp and Timberline Lodge by distance. I did not see any evidence of horses, but it can be used for that. It is one of several popular mountain bike complexes on Mt Hood. The Forest Service Zigzag Ranger Station is a good source of information. read more
