The areas west and north of Lake Khovsgol are formed by the alpine Khoridol Saridag, Ulaan Taiga, and Mönkh Saridag mountains. The center and east are less mountainous, but still hilly.Within Mongolia, the region is well-known for its natural beauty, and Lake Khovsgol is one of the country's major tourist attractions. The largest forest areas of Mongolia are located around and to the north of the lake, extending the south-siberian Taiga.
