Tsetserleg (also spelt Tsetserlik, Tsetserlig or Cècèrlèg) is the capital of Arkhangai province.
The town is located in a beautiful forested valley in the Khangay mountains; it has a population of around 20,000, and is generally considered to be the pleasantest among Mongolia's provicial capitals.
Buses for Tsetserleg leave from the Dragon bus station in Ulaanbaatar at 8AM on Mon, Wed, and Fri. The ride typically lasts at least 10 hours, and tickets must be purchased a day in advance. As of May 2008, bus tickets from Ulaanbaatar to Tsetserlet cost approximately 17,000 tegreg, around 15 dollars.
There are also microbuses that run between Ulaanbaatar and Tsetserleg. These are often very cramped (four across a bench seat), as drivers want to fit as many people in as possible to maximize profit. If possible, it is not a bad idea to pay for an extra seat to be left empty.
Tseterleg isn't very big. The city center and most hotels are in walking distance of the main attractions. If you don't want to walk, stand on the side of the road and stick your hand out. It won't belong before a car stops. Expect to pay between 500 and 2,000 T for rides around town.
