Ulaanbaatar vs Xi'an

Ulaanbaatar

Ulaanbaatar has one of the most extreme continental climates of any capital on Earth — short, pleasant summers and long, brutal winters with temperatures routinely below -30°C. Elevation (1,350 m), inland location, and Siberian-air dominance combine to produce January averages colder than Anchorage or Reykjavik. The tourist window is essentially June through mid-September; Naadam in mid-July is the festival peak.

Xi'an

Xi'an has a continental monsoon climate — cold winters, hot summers, and two distinct seasons of pleasant weather in spring and autumn. Air quality can be poor in winter due to heating and fog trapped in the Wei River basin. The Terracotta Army site is outdoor and uncomfortable in extreme heat or cold.

Ulaanbaatar

Ulaanbaatar has no metro — a long-discussed system remains unbuilt — and the city is served by buses, trolleybuses, and an explosion of ride-hailing cars. Traffic congestion is legendary; the downtown grid clogs solid in the 8-9 am and 5-7 pm peaks. The city centre (Sükhbaatar Square, museums, Gandan Monastery) is walkable in fair weather, but ride-hailing is the practical default for most tourist journeys.

Walkability: The central 1–2 km grid around Sükhbaatar Square is comfortably walkable in summer. Beyond the core, distances become impractical on foot — Zaisan is 4 km south, Gandan is a 25-minute walk from the square, and the airport or Terelj require vehicles. Winter drops walkability to near zero for anyone without heavy boots and windproof layers.

Xi'an

Xi'an has a metro system covering the city centre and reaching the high-speed train stations. The Terracotta Army requires Bus 306 or a taxi/Didi. The city walls are walkable from the South Gate metro stop.

Walkability: Moderate in city centre. Muslim Quarter and Bell/Drum Tower area walkable. Terracotta Army requires transport.
