I approached along the Mount Lowe Road from Eaton Saddle. I visited both Inspiration Points first, then Panorama Point and then Muir Peak. I descended the Castle Canyon trail just to the point where it passed along the wall of Peak 4668. From there I took a faint use trail which zig-zagged up the slope. It disappeared a few times, making the approach a bit of a bushwhack but a short climb of about 150' elevation gain. After reaching the summit, I could see a much better use trail which descended directly to the dirt road. I came back down that way before returning to the viewing tubes on Inspiration Point. Total mileage for all three summits from Eaton Saddle and back is about 10 miles.
