Following the ancient caravan route to Tibet, we head towards the base camp of Mount Chomolhari at 7316m. Considered as one of the most popular high altitude trek, this trek is quite strenuous. We cover remote highlands of the Lingshi, witnessing the nomadic lifestyles of these high altitude gypsies. Sights of Yaks and the wild blue sheep on the mountains are awesome. Himalayan poppies, primulas, gentianas and the spectacular rheum nobile fill the mountain side in the summer. We follow the trial to Thimpu along Wanchu river and through rhododendron and pine forest and the ruins of Barshong Fortress before reaching the upper Thimpu valley at Dodena.
