Great prepper for Whitney, if for nothing else than all the switchbacks. And an endurance hike to boot. Start low and finish high with a consistent never ending incline. Trail affords some nice views, but the big payoff is the summit with views of All the big SoCal peaks. Wilson, Baldy, The 3 Ts, San Jacinto, and Gorgonio. Make time and end your day in Wrightwood at The Yodler for post hike food and grog. Fun day!
