There is an excellent campground out of Lone Pine called Horseshoe Meadows...the site is at 10k feet so it will help you to aclimatize to the elevation. Head out of Lone Pine on the Whitney Portal road for about 3-5 miles...the road appears on the left and is called Horseshoe Meadows Road...take this roughly 25 miles to the end of the road...park and find a camp site, no reservations required and the fee is $6...this is also a good place to do a warm up hike...2 good hikes for warm up...Cottonwood Lakes, roughly 11.2 miles round trip and Cottonwood Pass, roughly 8 miles RT.
