Also known as Ravi valley is quite unexposed. But now the means of communication have made inroads into the interior parts of this valley. The scenery is charming and varied character presenting many delightful sights. In the lower parts, the trees grown are wild olive, pomegranate and fig trees mingling with the acacia, Shisham, Pipal and some other trees. Visitors get a good picture of small villages and hamlets extending over the landscape. On the mountain slopes, the fields are usually small in size and are arranged in terraces, the lower border of each being formed by a rough wall to make the ground more level for ploughing. In most part of the Chamba valley, under 2,550 meters, only two crops are reaped per year.
