I knocked this out last weekend. Started at 11:45pm the night before and summited at 4am. The night hike was a beautiful hike with flash lights and the moonlight. Sunrise on the way back down was beautiful.
This trail is no joke, so congrats on completing it! If you ever can make it back, check out the hike to Hunter's Peak which I think is on par with, if not even more rewarding, than Guadalupe Peak. We tend to visit this park in late spring/early summer or late summer/early fall. Obviously warmer, but you avoid the brutal winds that the park is known for. Thanks for the vids!
