Mt. Hood National Forest Hidden Lake Hike Hike 11 Length: 4 miles round trip Elevation Change: 700' gain Season: Late Spring thru Late Fall Difficulty:   Moderate Permit:   NW Forest Pass Required Features: This is a short and moderate hike. The hike begins to climb almost immediately and climbs along the side of a steep hillside within a dense forest. About a half mile into the hike you are offered the only opportunity for a view. At that point the trail levels off and remains an easy walk the rest of the way to the lake. Depending on the season, the Hidden Lake can resemble a large marshy pond. You must cross the outlet stream just before the lake and this can be tricky. If you would like a more significant challenge, after viewing the lake, continue on Trail #779 to the point it meets the Timberline Trail #600 (also the Pacific Crest Trail #2000). The only reason to take this difficult hike would be for the exercise or adventure. There are not significant viewpoint the entire distance.
