Mongolia: Ulaanbaatar – City Center
You can explore most of Ulaanbaatar city center and all the attractions in 6-7 hours (forget Lonely Planet’s 2-3 days recommendation). While the city is sprawling with housing complexes and the traffic is absolutely horrendous and standstill, the central part around Sukhbaatar square and all the slick glass towers is pretty compact and easily walkable. Architecture is a mix of modern and brutalist Soviet and the further you go away from the central square the more drab it gets.
