well i have made several trips in the region. once i covered from Jehlum (near the phatak on GT road) and emerged at KK after Khewra salt mines Choa saidan Shah and Ketas. once i made a trip to mianwali (a couple of times actually) and saw the kalabagh salt mines.
i have made a couple of trips to Soan valley and sakasar peak (also seen snow fall there). and many times to KK and nearby areas like nelawahn and Thandoi lakes and pools.
