Trail 3 is the most popular of the Margalla Hills hiking routes — five kilometres of steady uphill from the F-6 trailhead to the Pir Sohawa ridge, gaining about 600 metres of altitude. The path is well-maintained, signed and used by locals every morning before the heat builds.
Allow two hours up and ninety minutes down. There is a small drink stall at the halfway viewpoint. Start at first light in summer; in cooler months you can begin later and time the descent for sunset. Carry water; the path is exposed in stretches.
