Went up from East Fork, had quite the time navigating the ridgeline at the top. Felt out of it at the summit and struggled back to the truck. A good solid scramble and amazing views, well worth it.
I tried this one a few years ago but circumstances prevented me from getting up. I finally returned and got to the top. The view from the top is something else, but that's the case with any of the peaks around Big Basin. Went up via Hyndman Creek for a long 6-ish miles and 4500' gain.
The south ridge is a pretty fun scramble. Quick trip if you can drive to the end of the east fork road. As sawtooth Sean notes, no summit register right now. Very good views of wildhorse and the major pioneer peaks
East Fork up to the correct notch to get on the south ridge. Followed the exposed ridge to the summit. East walk off SW ridge and onto McINtyre. Cloudy 65F. NO summit register.
Backpacked into the basin for a few days. Climbed the ridge to point between Old Hyndman and Big Basin then followed the ridge to the summit. Nice stormy day but had a great climb. There are lot's of interesting routes to be discovered in this area.
Climbed Big Basin Peak from the Johnstone Pass trailhead with IdahoKid and IdahoSummits and almost no beta which made for a great time on a gorgeous day.
Climbed on a beautiful fall day with SuperDave and IdahoSummits. Saw one mountain goat, had an exciting scramble to the summit, and climbed Little Matterhorn on the way down-great day.
