The only detraction would be rude people not cleaning up after their dogs. :-( casey grote (2538) 6 months ago N/A: 63 Completed 61 Reviews great hike to an enormous mountain lake Justin Steele (76) about 1 year ago N/A: 1 Completed 1 Reviews Our Youth Group was there July 19-20 2013 and it was amazing. Gorgeous. The hike up to the lake and around it was pretty intense with the big elevation climb. But it was well worth the effort for the beauty to see one of God's hidden treasures! Beth Blakeman (224) about 1 year ago N/A: 6 Completed 1 Reviews Gorgeous!! Lots of different kind s of terrain. Lake is really low this year but caught a decent amount of fish! Island lake is beautiful. That is the place to camp if you do an over night! A must see! Kara Jordan (638) over 1 year ago N/A: 96 Completed 14 Reviews Mystic Lake is a pleasant hike, though the fact that its a reservoir is a bit distracting for me. "Aha, the pipe along the mountain side I saw on the way up is an aqueduct." Being somewhat of a purist, in my opinion, a backcountry destination that hasn't been altered is more appealing. According to the map, if a person continued down the trail to Island Lake you would set foot in a genuine wilderness area. I will give a plus for the scenic beauty that surrounds Mystic Lake. In addition, at the trailhead, I recall seeing a sign indicating grizzly bear activity. Once again, being somewhat of a purist, I guess I would consider that another plus.

Jessie Gauthier (145) about 4 years ago N/A: 0 Completed 2 Reviews This is a very popular trail, and a good family hike. Mainly a day hike, although there are many camping spots. Want a longer hike? Keep going and you'll reach Island, then Silver Lake. Both are a short distance away from Mystic Lake. It's a beautiful trail (I had my senior pictures taken off of the trailhead a few summers back.) Also at Mystic is a huge dam, which suprisingly doesn't take away any of the beauty of the mountain lake.
