Thanks for the input! If we hike Langley, I am hoping to be on the summit for sunrise, so both of these posts are very helpful.

Since I've never hiked Langley, I'm not really sure how much time to allow for a sunrise hike though. If I were staying at Trail Camp and hiking Whitney, I would allow 4.5 hours... 4 hrs for a leisurely paced hike with a 30 minute buffer to catch some of the cool things that happen before you actually see the sun.

Based on the the info above, how much time should I allow if we camp at:
1.CWL 3?
2. Long Lake?
3. Harvey's spot at the top of NAP?
