I hiked up the PCT from I-5 and then up the Castle Dome Trail to the base of the dome, it didn't look like anything I wanted to do solo, so scrambled around awhile on the center rocks. While having lunch there I heard some voices and finally saw some climbers coming down the dome. Now I know the route, just like the dotted red line shows for that page! Still not something I want to do alone!
Was on the way to Mt. Shasta when I saw this area by the roadside and figured I'd have a detour. Camped overnight then took off down the trail and shortly lost it due to snow fall. Reckon I did some unintentional climbing on Six Toe Rock before seeing the real path far down below, retreating then heading up between Castle Crags and Castle Dome only to find non-shifting clouds and the beginnings of a blizzard. Amazingly atmospheric due to no-one else being around.
