River
The Wang Chhu, also known as the Raidak, is a significant river that flows through western Bhutan. It originates in the Himalayas north of Thimphu and traverses the nation's capital, making it a vital lifeline for Bhutan's largest urban population. The river has carved a deep gorge into the landscape and flows through the districts of Paro, Thimphu, Chhukha, and Samtse. Its hydropower is intensively utilized by some of the country's oldest and most important hydroelectric plants, such as the Chhukha Hydroelectric Plant and the Tala Hydroelectric Plant. These facilities were instrumental in Bhutan's development as a leading exporter of clean energy. The river exits Bhutan in the south and flows through West Bengal in India to join the Brahmaputra. Along its course, the landscape changes from alpine regions to subtropical valleys, supporting a rich flora and fauna.

📋 Practical info
Getting there
The river is exceptionally easy to access as it flows directly through the capital city and main western valleys. Riverside promenades and convenient highway viewpoints are common and well-maintained.
Best season
The dry season from autumn to spring reliably provides the most stable conditions and clearest waters. The river predictably becomes turbulent and noticeably muddy during the intense summer monsoon period.
Terrain & paths
Within the capital limits, the banks are often paved or clearly graded, transitioning to a more rugged gorge further downstream. The surrounding natural slopes can be somewhat steep and heavily forested.
What to bring
Casual, comfortable clothing is perfectly fine for enjoying cityside views of the river. If actively hiking the western gorge sections, sturdy trail shoes and sun protection are highly recommended.
Parking
Numerous dedicated parking lots and roadside spaces are readily available throughout Thimphu and along the western highway. Visitors can easily park nearby and walk down directly to the designated riverbanks.
Safety
Even in urbanized areas, the river's current can be deceptively fast, so visitors should deliberately stay on marked paths. Utmost caution is needed when exploring the steeper, unfenced gorge areas downstream.
Time needed
A casual stroll strictly along the river within the capital usually takes about an hour to complete. Exploring the scenic downstream gorges can easily turn into a half-day scenic drive and moderate hike.
