This is the longest day of the trip and therefore very essential to start very early. We start at 5 am by climbing to Tsimola (4700m) After crossing the first pass and at the little summit one can have a superb view of Lunana, Jumolhari and Jichu Drake. This path is flat for another four hours till the climb to Gangla Karchula pass (5,080m). The view from the pass is breathtaking. The whole range of mountains, including Masagang, Tsendegang, Teri Gang can be seen, after the pass there is a very long descent to Tarina valley. Altitude 3,980m. Walking time 10-11 hours.
