What time should I start hiking Half Dome?

Most hikers take 10 to 12 hours to hike to Half Dome and back; some take longer. If you plan on hiking during the day, it's smart to leave around sunrise (or earlier) and then have a non-negotiable turn-around time. For instance, if you haven't reached the top of Half Dome by 3:30 pm, you will turn around.

This climb is hard! The granite surface has been worn smooth by the shoes of the thousands of people before us.

Angels Landing is 5 miles and 1500 feet gain. Half Dome is 3 times that - the actual cables are only a small part of the entire hike. Personally my biggest problem is how insanely steep it looks from the top when you have to go back down.
