We hiked 14 miles from Les houches to refuge de la balme campground. It was a cold night with our tent completely iced over during the night. we are doing the TMB in a counter clockwise direction. The trails are often very steep up or down often dropping 3,000 feet in only 3 miles. On a single day we often have about 5000 feet of ascent and descent.
