TheParo Chhu is a river of westernBhutan. It is a tributary of theWong Chhu, which is known as theRaidak in its lower reaches.
The Paro Chhu rises to the south ofChomo Lhari (mountain of the Goddess). Its glacial waters plunge torrentially through alpine meadows and deep gorges in theJigme Dorji National Park, and descend into a wide, open, undulating valley.[1][2][3] Sub-alpine and temperate forests are found along its middle and lower reaches.[1] A primetrout stream, it nourishes lush green rice fields and apple and peach orchards on its banks.[3][4][5]
The Paro Chhu flows through the Paro Valley, which is the site of one of Bhutan's main towns,Paro, and many important monasteries. The two best known monasteries here areTaktshang ("Tiger's nest" inDzongkha), andParo Dzong. Taktshang clings to a ledge of a high cliff approximately 15 km north of Paro. Taktshang and Paro Dzong are two of the finest examples of Bhutanese architecture.[6][7] Below the Dzong, a traditional wooden covered bridge called Nyamai Zam spans the Paro Chhu. The original bridge was washed away in a flood in 1969 and the present one is a reconstruction. Earlier versions of this bridge were removed to protect the Dzong. The bridge was also shown in the movieLittle Buddha byBernardo Bertolucci[8] Below the town of Paro, the river runs immediately to the west of Bhutan's only international airport. That airport is renowned for its hair-raising final approach.
The lower Paro Chhu is a good stretch of about 7 kilometres (4.3 mi) for beginner/intermediatekayakers. This stretch has many small, boulder rapids and wave trains. There is one class IV–V boulder choke, about 3 km from the put in, which can be run on the left and scouted from the right. It is suitable forkayaks only as the river is too small for araft to be enjoyable. After this, the river enters a short, sceniccanyon with more class II–III rapids. The stretch ends at Chhuzom. More experienced kayakers can continue down the Wong Chhu.[9]
Chhuzom (Chhu means river andzom means join) is the place where Paro Chhu and Wong Chhu meet. For many traditional Bhutanese this confluence is considered the union of a father and mother river. Paro Chhu represents the father and is sometimes called the Pho Chhu, Wong Chu represents the mother. Because Bhutanese traditions regards such a convergence of rivers as inauspicious, there are threechortens here to ward off evil spells in the area.[10] Each chorten is in a different style—Bhutanese, Tibetan and Nepali.[6][11] The upper reaches of Wong Chhu, above Chhuzom, are sometimes referred to as Thimphu Chhu.[12][13][14]
