The Thimphu Eco Park below the Changangkha Lhakhang, with large stretches of wetland within it, harbours diverse species of flora and fauna, and besides being a water reservoir, is also an important carbon sink. The 10.77 acres in the heart of the city, comprising mostly of wetland, has now been designated an urban park to protect the ecological wealth in the area. 

The One Gewog One Product Shop is located within the park premises.
