Ulaanbaatar vs Yerevan

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.

Yerevan

Yerevan has a continental climate with hot, dry summers and cold winters. The city sits at about 1,000 meters elevation on the Ararat plain. Spring and autumn are the most pleasant seasons for sightseeing.

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.

Yerevan

Yerevan is compact and the central core is walkable. The metro is limited but clean and cheap. Ride-hailing apps are the most convenient way to get around, with very low fares by Western standards.

Walkability: Excellent in the Kentron district — Republic Square, the Cascade, and Northern Avenue are all within easy walking distance. Sidewalks can be uneven and drivers don't always respect pedestrian crossings.
