Following some Essential Mongolia Travel Tips can make a first visit much easier. Check your nationality’s visa or visa-exemption status before booking flights, as Mongolia’s rules vary by nationality and purpose of travel. If you need an eVisa, make sure your passport is valid for at least 180 days when you apply and keep a copy of the approved eVisa with you. Your activities should also match the purpose stated on your visa. Mongolia has large rural areas, so travellers planning trips outside Ulaanbaatar should organise transport, accommodation and communication in advance. Weather can change significantly between seasons, particularly in desert and steppe areas, so suitable clothing is important. Travellers should also keep copies of important documents and follow local immigration requirements during their stay.
