The Margalla Hills are full of hiking trails that snake their way up ridgetops and down through forested valleys. Hiking Around Islamabad, available in major bookshops, provides details of hikes ranging from short walks to three-day excursions. It also provides a natural history background and handy hints for preparation. The walks can be steep, and it's usually hot and dry so take plenty of water and don't walk alone.
