The East Buttress of Mt. Whitney is certainly the best-known climbing route in the Whitney area, and for good reason. With ten high-quality rock pitches at moderate difficulty, it would be classic even if Whitney weren’t the highest point in the lower 48 states. But with that distinction, The East Buttress becomes a “must-do” for the alpine rock climber, a little harder and steeper than the more popular East Face.
Prerequisites
You need to be able to follow at the 5.8 level and have experience on trad multi-pitch routes (This level is harder than the rating of the route, but you will be at elevation, climbing with a pack and moving steadily for a good part of the day). Prior backpacking experience is recommended as is experience at altitudes above 12,000’. This is a physically demanding trip and you should be in good condition and have the ability to traverse broken and uneven slopes with a moderately heavy pack.
Inclusions
Price includes guiding, permits, group climbing gear, tents, kitchen gear, breakfasts, and dinners (you bring lunches, hot/cold drinks, and snack items).
Acclimatization & Physical Training
For proper acclimatization, we suggest spending at least one night at a moderate altitude, higher than 8,000 feet, just prior to the start of the journey. See our detailed tips on acclimatizing and physical training in the “Resources” tab.
Day 1
We meet in Lone Pine for a gear check before caravanning to the Whitney Portal trailhead. The hike in begins at the Whitney Portal trailhead, which is the same trailhead as the main Whitney Trail. This is one of the busier trailheads in the Eastern Sierra so expect some company at the parking area—sometimes quite a bit of company.
We start on the Whitney Trail but after thirty minutes or so leave this for the relative solitude of the Mountaineer’s Trail. This is a steep, seldom-maintained route with sections of scrambling, boulder-hopping, and loose terrain.
We usually reach Lower Boy Scout Lake (10,300’) in time for lunch and gain Upper Boy Scout Lake (11,200’) by mid afternoon. We take a good rest there and gather strength for the final hour push to camp Iceberg Lake. This is a very hard day with a gain of over 4,000’ so be prepared for this and remember to save energy for the climbing day.
Day 2
A more direct line and more difficult than the East Face Route, this offers technical climbing at elevation on impeccable rock. Some ten pitches of perfect climbing on a thin Arête lead directly to the summit. If the East Face Route is classic for its history this route is classic for its quality climbing and its position. We use the same camp and approach as the East Face Route .
The rope-up point is about twelve feet to the right of the start of the East Face. Several variations are possible for the first pitch, ranging from a 5.8 hand crack to the traditional 5.4 start. Both starts meet two pitches later on top of the Second Tower. A traverse to the right, up a ramp, and we’re at the start of one of the best pitches of the route: the spectacular 4th pitch ends at a tiny stance on the very prow of the East Buttress.
The fifth pitch is good too with delicate climbing on the Arête. Four more pitches of mixed face and crack lead straight up the buttress, past the famous Pee Wee Pillar and to the final summit blocks. We join the East Face about twenty minutes below the top, un-roping on the very summit.
We descend via the Mountaineers Route, to the north. With some fourth class rock and sometimes a bit of ice or snow it’s not a giveaway, but the technical climbing is over quickly; an hour or less after leaving the summit we reach the top of the Mountaineer’s gully and it’s all third class or easier back to camp.
Day 3
We return down the North Fork of Lone Pine Creek and plan to get back down to the trailhead in time for a lunch of the famed burgers and fries at the Whitney Portal Store, before heading home tired but satisfied.

Reviews
Kevin, North Ridge of Conness 2025
“Amazing experience. Anouk was awesome. Made the long day very enjoyable. Had great knowledge and skill to make the trip fun and safe. Had great patience and taught/reinforced alpine skills that I was trying to get out of this trip.”
Corey, Palisade Traverse 2025
“Dave is an exceptional mountain guide. His confidence and extensive route knowledge made a challenging route seem (relatively) chill. He’s affable and made me feel at ease, in particular when they’re not up to the level of climbing required for a clean free ascent on route (lookin at you thunderbolt summit block!). Moreover, Dave provided some great feedback on where to focus skill development to achieve my specific goals within my climbing (e.g., more confident trad leading). I’ll be back to climb with Dave for sure.”

Todd, Whitney East Buttress 2025
“There was good up front communication to set expectations. I appreciated the flexibility on dates and itinerary. Gear lists were very helpful for planning…Dave was excellent to work with. I like that he will set expectations and options and and let the client weigh in. He is patient and will not push clients. Rather, he will present options based on client progress, weather, etc. On a technical level he is very strong. I learned some new things from him on the trip which I appreciated. Would definitely recommend him and hope to climb with him again.”
Doug, Multiple 14er’s 2025
“Emma (owner) and Barb (office manager) with the front office were kind, pleasant, helpful and creative in making my CA 14er trips successful…I was also impressed about SMC’s AMGA certification as a guide company. This was probably the main I selected SMC over multiple other Eastern Sierra guide companies (which the other companies did not appear to have). It provided me reassurance that my guides for the various trips should have acceptable AMGA certification for my trips…Guides Dave, Louie, and Anouk were excellent and made me feel comfortable on all my trips…I am a huge fan of openness and transparency with communication. SMC did an awesome job and was willing and helpful with all my various questions and schedule modifications.”
Jason, Palisade Traverse
“What a fantastic trip put together for us by the Sierra Mountain Center. From the start Emma was fantastic and professional in the coordination efforts for our Palisade Traverse trip. My son and I had a 1:1 guide ratio and the guides, Dave Stimson and Tyler Logan, were exceptional. Exceptional in their knowledge of the route, their efficiency with rope craft and their trailside manner – despite the exhausting climb we had such a fun time. We are already planning next year’s outing with SMC.”
Fred, Mt. Whitney via the East Buttress
“Used SMC for a climb of the East Buttress of Mt. Whitney June 17, 2024. Great experience all the way around. Dave was my guide and I highly recommend choosing them for your Sierra adventure!”
Chris, Mt. Whitney via the Mountaineer’s Route
“I went on the Mt Whitney via the mountaineers route with Sierra Mountain Center. Our guide Louie made sure we were safe while helping us reach our goal of getting to the summit. Everything was explained clearly beforehand. I’ve never done rock climbing before and Louie did a great job of providing the needed instruction and coaching. Best of the best – highly recommended!”
