Changangkha Monastery is one of the oldest temples in Thimphu valley. It is built in the 15th century by a descendant of Phajo Drugom Shigpo, the founder of Drukpa school in Bhutan. The main statue here is an image of Avalokiteshvara. The district gets its name from Changangkha Lhakhang, which is situated on top of the hill that stands out above Thimphu and from where the view of the valley is superb.
The other activities while in Thimphu can be strolling in the town, and visit the mini zoo where you can see the Takin (national animal) or the Buddha Point from where you can view the beautiful scenery of Thimphu valley.
