Hiking the mid-summer the trail up South Sister is fairly free of snow and the climb becomes one of the most beautiful hikes in Oregon and is a yearly trip for many Oregonians. Strewn with wildflowers and skirting big glaciers the views are ample reward for the long and strenuous day.

We’ll start our day at the Devils Lake trail head and hike through large trees as  we approach the south side of South Sister.  We’ll pass by both the Lewis and Clark Glaciers before reaching the 10,358 foot summit. If you’re looking to spend the day with folks knowledgable of the local area TMG can help!

Hikers should be prepared for a long 8 – 10 hour day covering 5,ooo feet of elevation gain in about 6 miles.

Permit Restriction

We are able to schedule this climb Monday through Thursday between Memorial Day and Labor Day, because of limitations on all commercial permits in the Deschutes-Willamette National Forest.

South Sister Hike

Devil's Lake Trailhead

This is the standard hike up the South side of South Sister. While it isn’t technical, it is 5,000 feet of elevation gain and over 5 miles between the trailhead and the summit. At over 10,000 feet in elevation, the weather and conditions can change rapidly, decreasing visibility and bringing precipitation – even snow – during the summer months. This trip requires good physical fitness and preparation, as well as a backpack with food, water and layers for all possible conditions.

Elevation:10,385 ft
Style:Steep trail with patches of snow in early Summer
Skill Level:Entry-level

"I am very happy with my TMG experience. The guides were professional, personable, and extremely concerned about safety. . . I absolutely give highest marks to these guys. If you don't have much Alpine experience, or just want the security of seasoned veterans guiding you up this mountain, then I strongly recommend you sign up with them. Thanks, guys, for a great experience!!"

"What a fantastic experience gaining the summit of a mountain we've gazed on from Portland for 25 years! . . . We learned a great deal, had a ton of fun, felt in very capable hands, and had the reward of summiting on a beautiful clear day. The value of being with a professional, certified, guide and guiding organization was evident throughout. Kudos to the TMG team who were responsive, supportive, and fun to work with every step of the way."

"We booked 2-day overnight program on Mt. Hood with Timberline Mountain Guides. Our guides were great, . . super friendly and reputable. The program did not go as planned due to inclement weather but we still had fun and good experience. The guides were definitely flexible and provided guidance during the trip. I would recommend going with them if it's your first climbing trip on Mt. Hood for sure."

Next Steps

  • The Hayden Glacier on Middle Sister is a great first snow climb. It isn’t any steeper than South Sister, but it provides much more solitude than the South Route and an overnight camping experience in the Three Sisters Wilderness.
