At the foothills of Margalla, next to Islamabad Zoo, there is a Japanese Garden/Park. Although we did not see any signs saying Japanese Garden, but there was a sign mentioning Playland Children's parks. Only children accompanied by their parents are allowed, after paying a nominal fee. One can see Daman-e-Koh above the park
A beautiful park, with an excellent play area (swings, monkey bars, slides, etc) greets the visitors. There were some trees that looked like cherry blossom, so maybe the name Japanese Garden.
The children's adventure playground is a gift from Japanese. It is located at the bottom of the hill below the viewpoint, immediately to the right. The park has lots of fun activities for the children. If you are travelling with your kids you must go there.....
