Manali’s Beas Kund trek has long been a popular one. It brings you directly to the river’s source that runs through town. However, the scenery is a big part of why hikers like this walk so much. Think about this: Near Manali, three of India’s tallest mountains are surrounded by lush green meadows. The emerald lake from which the Beas River flows is also tucked away amid these meadows.
