I really liked the little 80 foot climb up the summit block. For a mediocre rock climber this should be cake (both up and down). Fantastic view from the top... I'm pretty sure that I remember actually looking down into Crater Lake. Way cool.

Lovely fall day
After having drooled over thielsen for three years, I finally found the time to hike up there. The hike was no disappointment, and now the mountain is probably one of my favorites. The route is truly fun- lovely scenery, interesting geology, and a lil bit of excitement near the top. The crazy rock formations are probably the best part of the trip, right next to being able to see the water in Crater Lake from the top.
Finally, I've noticed there are a lot of conflicting reports on the difficulty of the summit block. Here's the down and dirty: The last bit of climbing is 80 to 100 feet in length over very good, solid rock. Yes, it is damned near vertical and could be rated a 5.1 climb. Although quite easy with lots of good holds, the summit is quite exposed; if you mess up and fall, you will probably plummet about 2000 feet to your death. No, there are no anchors on top; bring some slings. Rappelling off the top is hella fun. If you don't have a rope, the downclimb should be pretty easy. Summary: Unless you're a little girl, you can do it.
Have fun!

Great day hike
One of my favorite Oregon summits. Witnessed one of the grandest sunset's of my life just below the summit!

Fun scramble
Just wish the 4th class was longer. It was so much fun, but shorter than I thought.
Went up with some friends and loved it! So the next weekend, went up again with two different friends.
I don't know what to call this route... Came north on the PCT and lost the trail promptly. Came over the SW ridge and into the bowl, then turned East and went straight up the snow and scree face ( the first trip, we popped on top of the peak to the south first).
Nice and easy scramble up the summit block. Prepped me a little for Broken Top and Mt. Washington later in the year.
Love this mountain! Will probably be a favorite for a little while.

Slip and trudge to the top with D. The summit block was a fun challenge. Feels good to have accomplished a long-time goal.

one of the most fun mountains i have been on, crazy steep, but no gear necessary for the brave, lol, saw a 65yr old man with crazy outdoor muscles bust up the mountain and claim the top.

My partner and I opted to bring a 30 meter 7 Mil. rope and a set of stoppers. It was too short to rappel the summit block so we just put a few pieces in on the way down. Seemed better than a heavy pack or a risky fall.

Perfect weekend for a camping trip. Melting, mixed snow and rock conditions prevented us from climbing the summit block. Super trip.

Favorite Hike Around
I hiked up Thielson three times in school, and photograph it whenever I can get down there. Its profile is so different and almost Alp-like. The view from the top, complete with those white moths, is indescribable. Can't wait to hike it again.

Awesome Climb
I loved the scramble at the top. The weather was great, but the mosquitoes were horrible! Definitely recommended.

Awesome climb! Glad I started early as there were a lot of people on the trail. First one up that day. The Class 4 was pretty easy. The views were great.

West Ridge
We climbed up the west ridge of Mount Thielsen. The summit pinnacle was a fun scramble and easier than expected. There were good handholds and no need for a rope. Good weather and view from the summit. Nice mountain climb.

Mazama climb that convinced me that class 4 can be done without a rope here. Of course, it was nice that our leader set a fixed line. If standing on the east side, below the rock, climb up the right side, it's much easier. We avoided a t-storm over Crater Lake, though it did make us nervous.
With fellow V Islanders Graham and Tony and my cousin Patsy from the UK and her husband Keith. Great climb up the W ridge and summit block in under 4h on a perfect day and as the last of a 3 volcano trip.
Soloed and downclimbed the Class 4 summit block with no technical difficulty. Bit stiffer than I expected I must say.
Objective danger was there aplenty, however, in the shape of an unspeakably incompetant and dangerous church group from somewhere in Boondocksville, OR. I'm thinking of entitling the TR "The Power of Faith".
Someone should remove or re-tie the rap station up there. Since we were soloing we had nothing to replace it with and as foreigners, didn't think it our place to remove it. There are two short tapes around the selected horn JOINED by the rap ring! Doh...........
