The principal attractions of a visit to Haa are the journey up and over the pass and the picturesque valley itself. Visits can be made to two famous monasteries, Lhakhang Karpo (White Temple) and Lhakhang Nagpo (Black Temple). The central shrine in Lhakhang Nagpo is said to be almost identical to theJowo temple in Lhasa. Legend has it that local deities assisted in the construction of Lhakhang Karpo.

Haa district is the ancestral home of the Royal Grandmother, Her Highness Ashi Kesang Choden Wangchuk, whose grandfather Gongzim Ugyen Dorji, commissioned the construction of what was formerly the district center, the Wangchu Lo Dzong. This structure shares a floor plan that is similar to the Wangdichholing Dzong in Bumthang,which became the seat of the 1^st and 2^nd kings of Bhutan ,with a great deal of the artwork and carvings coordinated by the same artisans that built its predecessor in Bumthang, the Wangchu Lo Dzong was built to replace the older Dumchog Dzong which was destroyed by fire. The prefix sar, meaning new, is sometimes used to distinguish this dzong from other similar structures in the country since its relatively recent establishment in 1915 sets it apart from other dzong in the country.
 
The staple crops of this large, fertile valley are wheat, potatoes, barley and millet. Yaks are herded in the upper reaches of the valley, and yak meat from Haa is considered a great delicacy by the townspeople of Thimphu. A day trip to Haa with picnic lunch by the river near new Haa Dzong is very pleasant in the warmer months of the year; when one can drive from Paro to Haa over the Chele-la pass (3,810m/12,573). On a clear day there is a superb view of Mts. Chomolhari & Jichu Drake from the pass.
