The valley gets its name from the river across it, Jaldhaka. Also known as the Dichu, it is a 233-kilometre-long transboundary river that runs through India, Bhutan, and Bangladesh. The river flows from Bitang Lake, known as Kupup Lake, near the Jelep La Pass in Sikkim's Gangtok District. Notably, the area is home to India's second oldest dam, the Jaldhaka Hydel Project, a cooperative venture between India and Bhutan. The dam is located near Bindu, India's last village. Furthermore, Jholung Bazar serves as the region's principal market and was previously shared by India and Bhutan. The area is noted for its fantastic splendour throughout the year, with views of the Himalayan snow peaks, the green hills of Bhutan in the distance, and the river dancing over boulders and rocks. Many bird species live in the forests and along the riverbanks. The region is also noted for its medicinal plants and orange, cardamom, and ginger plantations. There are many views from which to get a birds-eye perspective of the hills and valleys.
