I did Mt. Langley last weekend and I was wondering how many people did it as a warm up to Mt. Whitney, either day hike or backpack.
I found this trip to be a much sterner test than any of the more popular "big hikes" in SoCal. Baldy Village to the Summit...is 16 miles +6,000' but it's only to 10,064'. Vivian Creek to San G is similar, +5,950'+/- and 16 miles and Humber Park to San Jac. has 16 to 18 miles with 4,500' gain...short on distance, gain and elevation.
I will give you the first 6 miles to Langley are a piece of cake but the last 5 miles are tougher than Trail Camp to Mt. Whitney by a wide margin. Gives you the day hiker distance, elevation gain and the last 1,500' of gain to the summit will get your heart pumping. We will also give you something the aforementioned SoCal three don't...14,000'.
This would be my "big hike" prior to day hiking Mt. Whitney and to introduce Main Trail newbie backpackers to 14,000' summits.
One caveat...if you are strictly a trail hiker with limited route finding skills you might find this trip a bit daunting.
