North and Middle Sister

Ratio: 2:1
Length: 3 days
Price: 1 climber $1,350
2 $825 per climber
Dates: Custom dates are available in May and June
Location: Three Sisters Wilderness

North Sister and it’s twin Middle Sister both offer excellent alpine snow and ice climbing in Central Oregon. The famous “bowling alley” on North Sister, is a bit more secure in the Spring, but it’s also full of alpine ice and the challenge that it presents. While Middle Sister is technically easier, combining a climb of both into one three-day trip is a sustained physical challenge that rewards you with a rugged experience in the Three Sisters Wilderness.

On day one we will hike in and establish camp between Middle Sister and North Sister as we prepare for our attempt of North Sister. Early the next morning we’ll rise and climb to the saddle between Middle and North Sister. From here, we’ll gain the immense South Ridge of North Sister traversing some steep snow in the process. The summit pinnacle includes some steep snow and ice climbing. The climbing on North Sister can be serious, we will need to move well on a   We will descend back to our camp and prepare for day three.

After a well deserved night of rest, we rise early again and attempt Middle Sister via the steep North Ridge.  While not as technical as our climb the previous day the climber will encounter steep snow climbing in a visually pleasing setting.  Upon returning to our tents we will break camp and begin our hike back out to the trail head.

Both peaks require the use of ice axe and crampons. Previous experience is required.

Permit Restriction

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

North and Middle Sister

Three Sisters Wilderness

Combining these two climbs in a single trip is a strenuous and beautiful way to see the Three Sisters Wilderness. North Sister is more technically difficult and is the first objective of the trip. Afterwards, we will move camp to put ourselves in the best position to summit Middle Sister and hike all the way back to the trailhead in a day. This is definitely a challenging way to climb these two peaks.

"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."
