Went from the paved parking lot listed as trail head #3. My mileage came to about 1.4 miles each way, I think this is mostly due to going straight up the hill as opposed to following the use trails around the side of the mountain. Either way it was a 1400'+ gain so it wasn't necessarily the most gentle path. Took an hour up and about 45 minutes back down. Grabbed a pair of Geocaches while I was up there too.
Was with the Sierra Club on this one, so have no idea how we actually got to the trailhead (the page description seems a little different). Incredibly steep in some places (and a little hard to navigate on the descent). RT was 3 hrs for us; great workout.
