The Paa Chhu River is one of the major rivers flowing through the Paro Valley in Bhutan. Originating from the mountains, the river contributes to the rich agricultural lands of Paro and is a vital water source for both irrigation and everyday use in the area. The Paa Chhu joins the Wang Chhu further downstream to form the Thimphu River. Along its banks lies the Paro Dzong, a historic fortress and one of Bhutan's most significant cultural landmarks. The river's clear waters are frequented by locals and tourists for recreational activities such as fishing and rafting. Additionally, the river's serene environment attracts those seeking a peaceful place for contemplation and the exploration of Bhutan's natural beauty. The landscape around Paa Chhu River is characterized by lush forests, traditional Bhutanese architecture, and the majestic Himalayas, making it a captivating destination for nature lovers and adventure seekers. The river's presence in the Paro district enhances the picturesque beauty of this valley which is also home to the famous Tiger's Nest Monastery (Paro Taktsang), perched on a cliff face.
