I have done with a 2 dayer trekking (for novice to moderate hikers) trip to Dudipatsar Lake and I would like to share my experience with others who are thinking about exploring the magnificent lake. The Dudipatsar Trail is an approximately 18 km (11 mi) hiking trail in the Lulusar-Dudipatsar National Park of Khyber-Pakhtunkhwa. The trail goes along a tributary of the Kunhar River called "Poorbi Narr" in the northern Kaghan Valley. The average time taken to complete the trail is 5 to 8 hours.
Trek to Karambar Lake is a must in the bucket list of an adventure lover. Trek difficulty level is EASY but involves multiple hours trekking so prior trekking experience will be preferable. The trek is one of the most diverse treks in northern areas of Pakistan and has many entry and exit points to the lake. It is also one of the most beautiful treks. Karambar lake lies on the boundary of Broghil valley in Chitral and Ishkoman valley in Gilgit Baltistan. The easy and shortest route to Karambar lake is from Chitral side (via Mastuj, Broghil valley). It took us 11 days for the round trip from Islamabad with spending two nights at the lake.
