Real Mongolian life is in a ger.
Even if its capital Ulaanbaatar becomes every day more populated, Mongolia still keeps a strong nomadic spirit and this has its main symbol in the ger, the tent-house called elsewhere yurt. If you plan an excursion in the national park of Terelj try to arrange as well a visit to it and you will be maybe rewarded with some fantastic local food including khorkhog and aarul.
