In the morning after passing a small army post, the trail slowly leaves the forest line and gradually climbs into a beautiful valley, passing Tekithang, a winter home of yak herdermen. Lunch will be served in one of these huts. Lots of yaks will be seen today before we arrive at the Jhomolhari base camp (4,115 m). High mountains overlook the camp and visible nearby are the ruins of an old fortress used to guard Bhutan against Tibetan invasions. Altitude 4,115 m; Distance 15 Km; Time 5 - 6 hours. Overnight in Camp.
