There are numerous ger camps and resorts in the tourist zone before the Terelj River. The rest of the protection zones start after the Terelj River and become less touristy, less inhabited with pristine nature. The depths of the mountain forest are rich in wild animals, including boar, red deer, roe deer, fox, wolves, etc while birds of prey fly everywhere. Except for the natural beauty, Terelj was a mining area of smokestone, amethyst, and pure crystal till 1960.
