I'll be attempting Iztaccihuatl (17,800') and Orizaba (18,491') in Mexico. Before flying to Mexico City, I'd like to spend the previous weekend acclimating somewhere "easily" (relatively speaking) accessible in the Sierra Nevada, maybe as high as 14,000... but at least 12,000' or 13,000'.
Since White Mountain is probably the most easily accessible 14er, are you allowed to camp up there? I know you can camp at the Barcroft Gate trailhead (11,670'), but are you allowed to camp further up the road to the peak?
Are there any other "easier" places to get to high altitude in SoCal?
The only place at somewhat high altitude near the LA area is the summit of San Gorgonio. I think you can camp with an overnight permit up there behind the stone walls.
Other suggestions?
