Cathedral Peak - at the base of the route

Cathedral Peak

Amazing. Climb…read more Probably one of the best multi-pitch rock climbs I have ever done. We started very late and ended up going down in the dark. I don't recommend this for one main reason: The descent is not straight-forward by headlamp. I found the description from SuperTopo to be a bit confusing, so here's my description (in case you don't heed my advice and try to roll this sucker late in the day): You are going to want to down-climb the last 10-15 ft of the summit pinnacle. The section you JUST climbed up to reach the tiny summit. Down-lead this (or better yet, just leave your pro in from the ascent) and build an anchor at the base. (I know this seems like a stupidly short "pitch" to build an anchor for, but, TRUST ME. The rope drag is heinous if you try to go around the corner and then anchor-in.) Then do a running belay/simul-climb around the corner (you are now going AWAY from the face you just climbed up). Once around the corner, go slightly right (skier's right). Once you've done this, just keep going left and down, gradually, on easy 3rd class terrain (we took the rope off at this point). When it starts to look easy to go right, traverse right until you pop out on the other side of the mountain. You'll probably do some minor bush-whacking, just try to keep hopping on those big granite boulders! The SuperTopo seems to say that you hook back right a lot sooner (after going down-left), the terrain there looked like very run-out/, 5th class slab (read: skeery), so we did not do this. OK, now that we've talked about the boring part (getting down), let's talk about the FUN part: climbing up. It's 5 pitches of 5.6-5.7 on glorious granite with ample spots for pro. You can run it out with ease, knowing there is always going to be a place to get your nuts in. This is the complete opposite of "Snake Dike" on Half Dome in that regard. We did the far-left (climber's left) variation. I think it's variation "A" in the guide book. We decided to simul-climb the first two pitches, this was a good call. The beginning of pitch 1 is very easy (low-5th and even 4th class) by the time it gets more difficult, the leader will already be at the 2nd anchor and the second can be belayed up. If you're a strong climber you could even keep going and link all three of the first pitches! Every pitch is fun, with great moves and great positioning. I'd make sure you are not wearing a pack or gear sling for the start of pitch 4, as the chimney is kinda tight in the beginning. Or maybe I'm just getting fat? I lead the last two pitches by headlamp, a new experience, and shockingly more fun that scary. If you do this, I'd start either insanely early or insanely late, in order to avoid the crowds. Have fun!

Cathedral Peak is arguably the most beautiful peak in Yosemite National Park. Despite its beauty,…read moreand despite the fact that the trailhead is at the edge of Tioga Road and easy to find, there are no crowds. During my hike on this 7 mile round-trip trail, I encountered, at most, only twenty other hikers. The trail is an easy hike for adults and for little kids. There are no cliffs near this trail. This means that, unlike some of the trails leading to or from Hawkins Peak at Pinnacles National Park and unlike the fabled Kalalau Trail in Kauai, there is no danger rocks falling from above, and no need to worry about tumbling over the edge of any cliff. Once you have reached the 3 1/2 mile mark, you will be rewarded with a splendid view of Cathedral Peak, which is photogenic from any angle, and which provides a variety of photogenic rewards at different times of day. Near Cathedral Peak is a meadow with little streams, and orange-colored bedrock near one of the streams. Also in this area, is an exposed granite dome, similar to nearby Lambert Dome. My photographs show: (1) Me posing on a granite dome located next to a meadow. This meadow is just to the south of Cathedral Peak, (2) The trail marker sign next to Tioga Road, (3) The orange-colored exposed bedrock, and (4) Two photographs of a little stream that winds its way through a meadow, with Cathedral Peak in the distance.

I want to share my experience with International Alpine Guides! I just completed the Mountaineering…read moreEducation Course in Mammoth Lakes area and Dade Lake. I cannot tell you enough positive praise for this company and the education and my guides Cage and Cal! As a novice Mountaineer I was so nervous. This was my first time doing everything they taught us, outdoor rock climbing, hiking and camping at high altitude, snow school, using crampons, ice axes, climbing CRAZY rocks with heavy backpacks on! I def had the least experience of the whole group. Which btw my group was SO amazing I love them and will miss them! Anyhow Cal and Cage were so supportive every step of the way and taught me so much. They pushed me to my physical limits and gave me all the technical training needed. I felt safe and secure even when doing some hairball stuff. I will really miss those guys! Thank you so much IAG's! You made my dream come true and I'm coming back next year to accomplish Bear Creek Spire summit! (Weather dependent!) crazy mountain weather!!!! These mountains gave us some challenging wind and even snow!!!

I recently returned from a 7-day IAG backpacking trip to summit Mount Whitney in the High Sierra in…read moreCalifornia, my first trip with this company. The scenery was beautiful and our guide was very good. That said, based on my experience, I personally would not choose to use this company again. I am an avid backpacker and trekker and have had very positive experiences with other backpacking and trekking companies over many years, so my expectations were based on those past experiences. On this trip, I noticed a few issues, including some around food and sanitation that I also saw mentioned in other reviews. For me, the most significant concern had to do with how health, safety, and communication were handled. These were matters that left me feeling uncomfortable. I raised my concerns directly with the company's owners and we had lengthy discussions by phone and email. Ultimately, we had different perspectives and did not come to agreement. I'm sharing this review to reflect my own experience and in case it may be helpful to others considering a trip with this company.

Amazing experience with knowledge instructors. Great climbing location! Friendly and helpful…read morestaff during the booking process. Even helped us get accommodations nearby. Would totally do it again!!

Spent three days climbing with guides from Yosemite Mountaineering School. I'm sure all the guides…read moreare spectacular, but I can personally recommend Chase and Jake. Highly professional, impressively safe, and personable, not to mentioned astonishingly strong climbers. Chase and I spent a day cragging gearing up for a run up Half Dome's southwest face via Snake Dike. The end of our 12 hours together had much less talking, but Chase helped make the 6+ mile hike in much more enjoyable (as much as it could be of course) passing the time with fun stories and fun facts. We told some jokes, saw some nature, passed some hikers, and were first on the crag, setting us up for an awesome day! Jake and I climbed the 1100-foot East Buttress of Middle Cathedral and when my foot slipped while scaling a lie back crack and my life flashed before my eyes, I felt the rope tighten and stopped safely (only falling 6 or 8 feet of the 800 feet we had climbed thus far). Awesome day with Jake! Both Chase and Jake were excellent on meeting me where I was in my climbing ability, being a confident 5.10 leader, able to climb middle 5.11 but without much experience on Yosemite's granite I had a few tricks to learn to be successful. I highly highly highly recommend YMS to anyone new to the valley or wanting to safely experience what Yosemite has to offer!
