Rara Lake lies in the remote Karnali zone in the north and the largest lake of Nepal which covers 11 sq km – west of Nepal. The region is made up of long ridges covered with temperate forests and alpine pastures enclosing high valleys. Summer rainfall is low, but winter snow can be heavy and persistent. Since the region is fairly high and free from monsoon thunderstorms, the summer season is ideal for trekking. Winters are cold, but in the autumn season, trekking is rewarded with a profusion of alpine flowers.
