Moraine Lake is one of the most beautiful high mountain lakes in the Three Sisters Wilderness, and because this is a moderate hike, it is the perfect destination if you are a first time backpacker. This is also a great place to take your kids hiking because the lakeshore is shallow and not mucky and the lake gets relatively warm during the late summer months.

​From the north side of the parking lot take the South Sister Climber Trail #36, following a creek until you come to the road. Once you have carefully crossed the Cascade Lakes Highway, you will see the official trailhead sign.
