Paro lies on the banks of the Paro Chhu in the centre of a broad valley - the only area in the country large enough to allow a plane to safely land. The fertile and productive soil has made the local population relatively wealthy, reflected in the standard of the local buildings, including probably the finest dzong in Bhutan. Reached by crossing a wooden bridge over the river, it was used on several occasions to defend the valley from Tibetan invasions. The former watch tower on the hill above now houses the National Museum with exhibits including a fascinating collection of pottery, armour, thangkas and a complete temple. Outside the town, a trail through the forest brings you to Taktshang, the Tiger’s Nest monastery that clings to a sheer cliff – well worth the climb for the far-reaching views.
