Hey there! I think you'd have to be pretty physically fit to do it without a guide and donkey. I would consider myself pretty physically fit, going on treks/hikes/hitchhiking/walking for very long periods of time. Sometimes days. And this was beyond a doubt the hardest thing I've ever done, physically. It's a very steep hike in a very high altitude, and I think the altitude really messes with you as well as the incline. I would literally sometimes take 3 steps and have to stop.
