The road approaching Mongar is one of the most spectacular journeys in the country. It passes over sheer cliffs and through beautiful fir forests and green pastures. Travelers passing this route will have the opportunity to visit the Rhododendron garden. There are countless varieties of rhododendrons here and on clear days you can even catch a glimpse of Gangkhar Puensum (7541 m), a strong candidate for the world’s highest unclimbed mountain.
