So my goal next year for the Whitney area is to do Mt Williamson and Mt Whitney in one hike. Have other hikes planned for other areas (including a big Salkantay to Machu Picchu trek in Peru), but wanted to do some planning on this one now (since I'll have to get the permits soon).

So my first possible starting point is at the Shephard's Pass Trailhead (naturally).

Alternately, I was thinking of going in via Onion Valley. A little longer (okay, a lot longer since I'll have to pop over to Mt Williamson and back to the JMT), but would give me more time to acclimatize before trying to summit Williamson.

I rushed my acclimatization this year when I did Mt Langley first and it cost me my 2nd Whitney attempt. This would force me to spend some time at lower altitudes on the way to Williamson.

Looks like Kearsarge Pass is the entry point.

Any thoughts on which is the better hike? (scenery and hiking difficulty).

Anyone have rough mileage for the two hikes.

I'm planning on a full 9 days (Sat to Sun) to do either of these hikes, but what are the likely number of days for each starting point, summitting both peaks, and exiting via the Portal?

July or August would be the timeframe.


Thanks.
