Mongolia is relatively safe, but violent muggings and attacks do occur. Petty crime is common in Ulaanbaatar, particularly in markets or other crowded public places. Watch out for pickpockets. Be wary of large groups of street children and teenagers, who sometimes harass pedestrians for money when entering and leaving vehicles, pubs and restaurants. Keep passports, money and other valuables in a safe place. Report any theft to the Pick-pocketing Department of the Police: telephone +976-93022480; the police can provide a letter for insurance purposes.
Mongolia experiences extremes of weather, from +35C in summer to -40C in winter. Even in summer, evenings can be cold because of the altitude and weather conditions can change without warning. There are long distances between settlements. Take appropriate provisions, including warm clothing, food and water if you are travelling outside main urban areas.
In recent years there have been occasional instances of civil and political unrest resulting in demonstrations and in some cases violence. On 16 September 2013 there was a political demonstration in central Ulaanbaatar during which several rifle shots were discharged. No injuries were reported. You should avoid large gatherings and demonstrations.
