"Don’t think I went up the standard way , but it went . I biked from Dutchman flat sno park as I thought I could avoid wilderness permit , but when I got to TH it seemed like they wanted me to have one anyway. Confusing! Thankfully the Gestapo weren’t out checking papers today. Todd lake trail is nice and cruisy all the way to green lake campground. From there I headed right toward the waterfall that you can see on the mountain in the distance , and a faint trail provides loose, but class 1 access to the base of lewis glacier peak where it merges with standard trail. Lewis glacier peak shouldn’t take more than 15-20 mins . From there it got kind of annoying , wasn’t expecting it to be that loose and dusty. On the rim, I dropped down a class 3 exit and scree slid down pretty much all the way to the saddle and then walked up to hodge crest . I would track a gps or make sure you know what exit you take as it all looks the same on the way back up. It is also extremely loose to get back. Once you are back on , its smooth sailing to top.

"1hr club on bachelor . Had to go goggins mode toward the end to get it in 1hr. Nice busy trail all the way up. Sisters looking nice in the distance , I think I’m going to try for north and middle sister next week unless someone wants to come pick me up at devil lake and take me back to pole creek so I can link up a three sisters traverse :) " — joshortman • Aug 12, 2023
"We got lucky with the permits, obtaining one 2 days out. Tough but beautiful hike. Haze and wildfire smoke did a number on the views. We were able to see the area near South Sister and some of the tall peaks poking above the smoke, but nothing for views when it came to long distance stuff. Lots of dust on the trail. Again, really tough hike. " — newenglandwarrior • Jul 26, 2023
"3 days hiking around South Sister with AK and LC ended with a picturesque summit. Started summit bid from Moraine Lake camp up the climber's trail and found perfect conditions throughout. Took about 3 hours 20 minutes from Moraine Lake camp to the top. Mosquitoes plentiful throughout our trip. Less snow than past for this time of year." — zachmitch • Jul 10, 2023
"First elevation in a couple of months but body is reacting at acceptable levels. Speed up still at a good pace.
Can’t believe it is snowing on the middle of June. Summer please turn up!" — oregon-mt-goat • Jun 19, 2023
