Beas (Sanskrit - Vipasa) is one of the five rivers that give the Punjab (“Five Rivers”) its 
name. It rises at an elevation of 14,308 feet (4,361 m) in the Rohtang Pass in the Himalayas, 
in central Himachal Pradesh. From there it flows south through the Kulu valley, 
receiving tributaries from the flanking mountains, and then turns west to flow past Mandi into 
the Kangra valley. After crossing the valley, the Beas enters Punjab state and veers south and 
then southwest to its confluence with the Sutlej River at Harike after a course of about 290 
miles (470 km). The Beas River was the approximate eastern limit of Alexander the Great's 
invasion of India in 326 BC.

Chamba Pattan, is on the banks of the River Beas, about 10 kilometers from Pragpur. It is a 
great picnic spot with a very friendly boatman who will ferry you across for a minimal fee.
