> Come on now, Steve, you just need to hike longer those days.
Forgot to distinguish... At the end of the day hiking, I can and do sleep pretty well. But this is a thread about acclimation. It's when I drive to the trail head -- or to Horseshoe Meadows, and try to sleep -- that I have trouble.
A favorite way for me, (as long as the hike doesn't start too high in the altitude): On a JMT section, we drove to Tuolumne Meadows, eating dinner near the trail head. Then set out about 8 pm, and hiked for 3 hours, with headlamps. The frogs singing in the meadows as we headed up the Lyell Fork were memorable. That night, sleeping was easy!
