What a hike! I hiked this trail 5 years ago and seemed to forget how hard it is. We started just before 8am, but an earlier start would have been better. The hike up to the base of the mountain is pretty easy going, the view of South Sister and the surrounding peaks is incredible. As everyone else states, the “Red Mile” is no joke! Took just about an hour for that section alone. Once at the top, all your effort is rewarded with spectacular views of Middle and North sister as well as the surrounding area/ peaks. Took roughly 8 hours round trip and just about 14 miles. Pace yourself and bring plenty of water. For me, this one was more of a mental battle than anything else, but just keep moving and you’ll get there! Saw a ranger on the way down that checked our permits, so make sure you get em before you go!
