Few years ago, I was crazy enough to do the Cactus to Clouds Trail during the month of February; 500' to 10,834' for an elevation gain of 10,334', in one day. The trail basically starts in Downtown Palm Springs and ends up at the top of Mt San Jacinto.
12 miles to the top of of the Palm Springs Tram 500' to 8000'
6 miles to the summit 8000' to 10,334'
6 miles back to the tram
24 miles in a day while hauling winter gear (ice ax, crampons, etc)
Then take the tram down for free (used to be free for the one way trip down, but I think there is a fee now). The tram operators figured who would hike up to the top of the tram anyways?
