Mongar lies in the eastern Bhutan. The journey from Bumthang to Mongar is one of the most beautiful in the Himalayas, crossing 3800m high Thrumshing La. Mongar is located on the hill top. This place is of little interest but people spend a night to continue with their journey to the further east. Mongar Dzong is the newest of Dzongs in Bhutan built in 1930s. This dzong was built to replace the Zongkar Dzong which has remained in ruins. Mongar Dzong is built in keeping with the tradition of Bhutan where no drawings or nails were used.
