Trout Lake is a tough hike up and over a ridge to the next valley over. It's one in a string of "paternoster" lakes. The lake has a natural log bridge, which makes it a great spot for bears to fish. It's a place with a historically dense population of grizzly bears, and the site of one of the two "Night of the Grizzly" attacks in the 1960s.
While it was a long hike and killer on my already sore legs, my friend Sam and I really enjoyed the views we got as we dropped down into the valley and picnic-ed on the lake shore. I ate my weight in huckleberries, which was fantastic as well.
