Bhaba Pass connects the green and fertile Bhaba valley on the Kinnaur side with the barren high-elevation Pin valley on the Spiti side.

National Highway 22 runs alongside River Sutlej until Wangtu gives way to a narrow road leading to Katgaon and Kafnu.

A moderate climb towards a glacial fed stream Bhaba river, to Bhabha Pass at 4,890 metres (16,040 ft) elevation to enter Pin Valley in Spiti is a challenging adventure.
