The Kepler Track is a 3 day 61 kilometer (41 mile) track. It is rated as moderate to hard in degree of difficulty. On the second day, I had 1.5 hrs of hard SNOW while I was walking. It was beautiful and aggravating at the same time. It hampered my view for a while but later the weather cleared. The bunk houses where we slept were like freezers and only your sleeping bag kept you from freezing. People from all over the world especially Germany.
