25 min drive ahead of Jalkhad is the location called Besal. From this point the trek to Dudipat Sar Lake starts and Mulla ki Basti is 1 hour before Dudipat Sar Lake.
The trek till Mulla ki basti is around 7-8 hours and is not advised for families. The first 3 hours are the toughest and then it is walk in the valley for next 4 hours. Temporary tents are usually installed in peak season by locals at Mulla ki basti but not suitable for family in case somehow you manage to get there.
Better to visit Nuri Top and Babusar Top on jeep and come back to Naran by evening.
