Lhakhang Karpo in Haa

Lhakhang Karpo and Nagpo (White & Black temple):

The two important temples in the Haa district, the Black Temple and the White Temple were built at the same time as Kyichu Temple in Paro (7th century AD).

Haa Gonpa temple:

It was built at further up the valley at the site where a lame pigeon, actually a bodhisattva in disguised form, was found by a local farmer who was drawn to the spot by a mysterious fire seen on several successive nights and by the unexplained sounds of oboes and trumpets (musical instruments closely associated with Bhutanese and Tibetan monasteries).

Three Brother Hills: 

popularly known as Miri Punsum, the 3 sacred mountains in Haa. 

Sacred oak and the upper house:

Near the Black Temple there are two houses near a sacred oak tree where the local deity once appeared as a winged creature, scaring the local people (the valley is divided into a number of areas, each under the influence of a particular local deity predating the arrival of Buddhism— see Bon religion). The residents of the two houses gave offerings to the local deity.

Wangchu Lho Dzong in Haa

Wangchu Lo Dzong:

The Gongzim Uguen Dorji, grandfather of Royal Grandmother Ashi Kezang Choden Wangchuck commissioned the construction of what was formerly the district center - Wangchu Lo Dzong. It was built to replace the older Dumcho Dzong, which was destroyed by fire. The structure of the Dzong resembles the Wangdicholing palace in Bumthang, which was the seat of the 1st and 2nd Kings.

Chele-la pass over 13,000 ft to the west above the Paro Valley is the highest road pass in the country and has amazing views of the Himilaya and most significantly the magnificent Jhomolari and some more.
