Built on the cliff, Omba Ney is the Taktshang of the eastern Bhutan. It is located within the holy site where the letter OM can be seen on the rock face. It is one of the three unique holy places linked to Guru Rimpoche, the other two are Aja and Hungrel. There are temples, caves and various sites of religious importance. A short crawl through a narrow cave passage on the cliff above lhakhang will cleanse you of your sins. It is about 3 hours walk from Nangkhar Gonpa or you can also reach Omba from Kheni village after a 3 hour climb.
