Though the Haa Valley is one of Bhutan’s lesser-visited destinations, this region just west of Paro is in fact home to some of the country’s greatest treasures and oldest holy sites. Haa Town is the main settlement here, recognisable for its ornate homesteads and buildings adorned with painted pillars, pretty wooden eaves and exposed beams – all topped with traditionally tiled roofs. You’ll also find a busy bazaar and handful of restaurants. Elsewhere, around the valley lie two of Bhutan’s oldest (7th-century) temples - Lhakhang Kharpo and Lhakhang Nagpo, the cliff-side nunnery of Kila Gompa, itself a holy site for over 1,200 years, plus a string of traditional villages, rice paddies and remote walking trails.
