Daman e Koh is a hilltop garden and viewing point north if Islamabad located in the margalla hills.
On a clear day you can see all of Islamabad and its green clean surroundings. Indeed a great opportunity to see how beautiful the city is.
You will encounter numerous monkeys that will literally attack you and snatch your edibles, so be fore warned. They are not afraid of humans and kids should be monitored at all times.
It has some kiddy rides and jumping castle, but it is better to avoid these and enjoy the natural beauty.
Overall a great experience not to be missed.
