What a lovely place! The views are gorgeous! Hiking with not enough water or food can be very uncomfortable, I guess it will be better next time as you all now have experience.
How about the feet? So many hours walking along the trail is not easy. From my personal experience with trekking I have noticed how bady feet can get without proper shoes. I just ordered some trekking shoes because I realized I can't walk for hours in normal shoes. Blisters, pain, sore soles.... And I have seen special socks for this too, as they reduce discomfort. Were you prepared in this area? Or did your feet hurt too after this?
