Half Dome from Valley floor at night

[phunhog]

I did this as a trail run about 8 years ago. As I recall I left Happy Isles about 3:30-4 in the morning. Power hiked the Mist Trail and ran the rest. I got to the shoulder of Half Dome at sunrise. As long as you have a good headlamp and stay on the trail it shouldn't be a problem. It is actually really, really nice to have the trail to yourself and be up top before the hordes of people. If I remember right I was back in the Valley before noon.

UPDATE: I totally skipped out on HD because the group I was going with wanted to stay in Curry Village--no thanks!
So I did Clouds Rest instead, alone, with no problems, and it was fabulous! Took me 7 hrs total with 1hr at the summit.

Hantavirus not your thing?

Not so much. I was also very happy to avoid the hordes of people in the Valley.
