There are 2 possible routes that would suit u.
One is from M2 Exit of Lilla Interchange, and the other one is from Kallar Kahar Interchange.
In both cases, u reach Pail Town on Kallar Kahar-Sargodha Rd. From Pail, u move westward and after few kms, turn right on Jaba Mor. Few kms from Jaba Mor, u turn left to enter in Soon Valley. Drive straight for about 15-20 kms and u would reach Khabeki Lake.
