Daman-e-Koh is one of the most famous outing spot of Islamabad. It offers lovely views of twin cities that are Rawal lake and Murree hills. Also there is a restaurant offering good meals from morning till night.
Daman-e-Koh on the Margalla hills gives a splendid and much glamorous view of Islamabad. Road winds up from north end of 7th Avenue. The road passes through various woody areas and hiking trails, this is a place where several monkeys are visible on the road (because visitors feed them). There are 
couple of snack bars and now the area has been renovated with golf cart taking you around.
Another cool spot above Daman-e-Koh is Pir Sohawa (approx 1200 m and 9km). The government has laid down a proper road, and even lighted at night. The spot has become a good picnic area with various BBQ restaurants cropping up. The hill gives a splendid view of Islamabad below, and the temperature is 3-4 degrees below the normal temp.
