Brholler: Speaking of which, do people ever go part way, to Trail Camp, and then, if bad weather happens on Day 2 just sit tight and turn it into a 4-day trip by taking a day off at Trail Camp? Do the permits allow for this?

I asked a Ranger a very similar question answer to this last Sunday 6-15. I did Whitney up and back in a day on the 16th.
If you are having trouble of any kind on the ascent and need to extend the stay in the Whitney Zone, you are either poorly prepared, lack sufficient training, or the weather conditions are severe and should turn back. If you are having problems on the descent however and require extended time to hike out, that IS allowed, for obvious reasons. I know it sounds a bit strange, but if everyone decides to extend their trip a day or two or more, then the area becomes over crowded, which the permitting process is designed to prevent.


I would suggest you call the Lone Pine Ranger Station and ask them that same question.
Happy Trails and the best of Success to you on your climb.
