I did this tour with my brother last month, a bit late to post the pics (H)
The best time to visit the Soun is February-March or September to November when the weather can be enjoyed the most. We were a bit late but this was the only free Sunday so off we went to ride Our destination was Ochhali Lake in the Soun Valley, District Khushab.
Total distance covered, from my hometown Jauharabad to Uchhali 150km
Time consumed= A little more than 6 hours
Track= Road+Off-road
