Kars is a city in Eastern Anatolia. It is most frequently visited as a jumping off point for travelers going to Ani, but it is a viable destination in its own right for its 19th century Russian imperial buildings, and, of course, its role as the setting for Orhan Pamuk's famous novel Snow.
Kars is one of the highest cities in Turkey, situated at an altitude of about 2000 metres over the sea level. Complemented with the distance to the sea, this makes the climate of this area the harshest in Turkey with winter temperatures regularly below -30 C at nights (and no warmer than -15 C during the day). There is not a real summer season in Kars, only a short spring in July and August (this is also the wettest season) and a long, bitterly cold, and heavily snowy winter during the rest of the year. Keep in mind that nighttime temperatures can fall below zero degree (Celsius) in any time of the year (even in August).
By bus - most companies serve Kars - though you might need to change bus at either Erzurum or Igdir, depending on where you come from. Be sure to check whether there are services available.
There are a few taxis serving the city centre. It's a pretty small place so it's quite possible to cover it by foot.
Kars Castle - situated on the side of the hill facing the city, Kars Castle is one of the few sights to see within Kars. It's a short climb from the city centre, and is worth climbing for the view of the city.
Russian/Baltic architecture along the grid of old town's streets, realized during the Russian occupation of the city in 1878–1918, singles out the city in Turkey. Fethiye Mosque (Fethiye Camii) in the city centre, originally built by Russians in the occupation period as a church, is the only mosque in Turkey having that distinctive architectural style.
The Church of Apostles just below the castle, now known as Kümbet or Kethuda Mosque (Kümbet/Kethuda Camii), is also well worth a look. The building was originally an Armenian church built in 10th century, and upon capturing the city, Ottomans converted it to a mosque in 1579. Later, when Russians came over, it became a church again, this time serving Russian Orthodox believers. After the Turks took back the city, it served for non-religious purposes for a time (such as a warehouse), and in 1998 consecrated as a mosque again.
Read Orham Pamuk's novel "Snow" which takes place in Kars.
Gravier cheese is delicious! You can enjoy having some from the shops near to castle. You can try the Soldier Souvenirs Passage on the main street with a lion statue sells stuff for rare collector's items.
A local speciality is goose (kaz), usually made into a stew.
Ani - A visit to Eastern Anatolia is not complete without a visit to the ruins of the City of Ani, which is situated some 45km away from Kars. It is best to charter a taxi or get a guide.
