Ahh, I've got it. Mount Hoffmann in the center of Yosemite National Park. It is over 10,000 feet high. There are two or three routes to get to the summit. The way I go, it is five miles to a camp spot, then another few miles to the top. Another way, and it is less than five miles total. The daughter of some friends climbed to the summit when she was four years old, so how bad can it be? This is in the geographic center of Yosemite, and you can see most of the entire park boundary from here. There is a summit register box, and there is one tough marmot that lives there, and it will steal your food. Wilderness permits are required if you camp up there.
