"Back for revenge on this . Got a nice 9am alpine start on this. Couldn’t have been a better day either , not a cloud in the sky and around 60 degrees on summit. Take the climbers trail to save some distance . It is not obvious where it branches off so have a gps for that and the summit block. Once you get to middle /north sister saddle , it’s about 1000ft ascent of some choss which makes for some nice scree surfing on the way down . Follow the faint but good path along the ridge , making sure you are on the correct side of the ridge . For the most part it stays on the left . It’s not hard to follow, only had to pull my phone out a few times . Follow path all the way to bowling alley, if you are not on a faint trail or doing anything harder than easy class 3, you are in the wrong spot . Bowling alley is downright easy, just make sure you have gps and go up the right gully. Plenty of solid rock for hand and foot holds . Maybe one or two class 3 or 4 moves , once you get to the second (black and blue) of three slings , the “hard part” is over . More easy super solid class 3 on summit block and then you are on top. This peak is not nearly as hard as it’s made out to be . I’d say it’s a..." — joshortman • Sep 15, 2023

"Fail on n sister today . Absolutely zero visibility and extreme winds / hail / rain forced my hand about 1200 ft below the summit. Extremely frustrating dealing with this consistently crappy weather around here" — joshortman • Sep 3, 2023

"October 1, 2022. Second attempt at this mountain. I thought for sure I could navigate the ridge to the summit and I had the infographics from summitpost.org. It proved more difficult than I anticipated to determine the correct route and I decided to call it instead of winding up in a stupid area due to the social trails leading to the wrong places. Also heard that there was a group of six and a group of three in the Bowling Alley. Very windy on the ridge. Turned around in the same place as April. " — runningvegan • Oct 1, 2022

"April 2, 2022. Turned around at 1:30pm at 9,735 feet on the top of the loose gully. We were worried about the snow softening up too much on the traverse/climb back from the summit and did not want to be stuck waiting for it to refreeze. Repelled down from where we turned around. Bluebird day with warm weather. An earlier start may have led to a successful summit, we saw one party of two on the summit block. I cashed my skis near the bottom of Hayden and skied down until I hit the trees." — runningvegan • Apr 2, 2022

"Started at pole creek trailhead at 5:30am and headed up camp lake trail until about 6200 ft when I jumped off and started overland towards the SE ridge of North Sister. Made the ridge by about 8am and began my ascent around the gendarmes. I got pretty lucky picking my route and never had to retreat when choosing left or right around the obstacles, although the exposure on some where pretty hairy. I made the intersection with the south ridge around 10 and thanks to the detailed info on summitpost started making my way along the upper ridge. Once I arrived at the terrible traverse I was glad I had lugged the ice axe and crampons up, since the snowfield was still about 25-30 ft across. I felt a little ridiculous since it took longer to put the crampons on and off than it did to actually cross the snowfield, but it would have been impossible without them. The other side of the snowfield was nothing but rotten rock and prayers for about 50ft. Definitely is the most exposure and worse conditions that I have climbed on to date. I was actually relieved to climb up some solid rock into the deadly bowling alley. After the traverse, the bowling alley felt too easy. A quick ascent up to the to..." — oregon-mt-goat • Aug 29, 2014
