Borith Lake is a lake in Gulmit, Hunza Valley in Gilgit–Baltistan, Pakistan. Borith is a hamlet in the surroundings of the Borith Lake to the northwest of Husseini, a village near Gulmit, Gojal, in the upper Hunza. The altitude of Borith is roughly 2,600 metres (8,500 ft) above sea level.
It lies approximately 2 km to the north of Ghulkin, a saline body of water occupying a small hollow at an elevation of 2,500 meters (8,200 feet). The lake can be reached via a 2 km unpaved jeep route from Husseini village, which lies adjacent to Ghulkin village. It is also accessible by a 2-3 hour trekking route directly from Ghuylkin, across the end of the Ghulkin glacier. The lake receives melt water from the Ghulkin Glacier
The site is a sanctuary for migrating wildfowl and is often visited by bird-watchers and nature lovers. To witness the large number of ducks arriving from the warmer parts of southern Pakistan, one should visit between the months of March and June. The birds rest here on their way northwards to the cooler waters of central Asia. Similarly, from September–November, the event occurs in reverse with the onset of winter towards the north.
A short trek of one hour each way brings visitors to Ghulkin Glacier. Hikers can follow the trekking route towards Borith Lake as far as the edge of the glacier, and return by the same route.
