From Kars, there is no direct bus. First you have to take a bus (company: Serhat Iğdır) to Iğdır (20 TL) and transfer to Doğubeyazıt by minibus (8 TL), a short distance away from where the bus stops in Iğdır. Road between Iğdır and Doğubeyazıt passes by Mt. Ararat offering fine views. (This info is valid as of May 27, 2014.)
Ishak Pasa Sarayi is a palace 5 km outside the city (entrace fee: 5 TL). This ancient fortress/castle/mosque is stunningly beautiful, and is a must see when in Dougbeyazit. Try to go on a dry, sunny day. The old town is nearby. Trek a little bit further up, and you can visit the tomb of Ahmedi Xani, the famous Kurdish poet and philosopher, and the ruins of the Urartian castle. The area is also famous for the rock formation assumed to be the remains of Noah's ark. You may also visit the meteor crater in the vicinity of the Iranian border.
For a taxi from the town center, expect to pay approximately 10-15 TL one way. Worth considering asking the taxi driver to wait at the Palace.
There is a dolmus service (2TL) to the Palace; but hitch-hiking may be quicker.
Alternatively, it´s a very stiff walk all the way up (or down), in summer possibly dangerous even (there are some very aggressive dogs along the way).
Climb Mount Ararat (5,137 metres/16,854 ft), on the borders of Turkey, Armenia and Iran, supposedly where Noah's Ark landed. Guides and vehicles are available in Dogubeyazit. The climb is long, but there is a fairly easy route from the south in late summer for climbers who are familiar with the use of axe and crampons. Snow covers the last 400 m (¼ mile) year-round. There are two possible campsites on the mountain, and the glacier begins around 4,800 m (15,750 ft). International climbers need a climbing permit that can be obtained through the Turkish Embassies or, the easier option is to let your guide's company do it. Expect the authorities to process your permit application in two months. You also need a licensed guide to accompany you on the trek. People most often attempt to climb upp to the summit and return to Dogubayazit in 4 days. However, you may need more time to acclimatise, so it can be wise to add an extra day.
You may also want to climb other mountains in the region, such as Mt Suphan, as part of your acclimatisation.
The only things you might want to buy (because it is hard to get it anywhere else) are special postcards for soldiers that are in nearby military base. Also, if you are here in winter, you can find a lot of warm military clothes in the shops along the main street.
Try to get a rare Abdigor Kofte. It is a fist size meatball on the pilaf but it difficult to find because not many people know how to cook it. This dish cannot be found anywhere else. It is a local delicacy that can be found only in Dogubayazit.
Hotels are numerous and near by the main bus station. If you arrive from Van by dolmuş, turn right out of the station (more like a car park), then veer left into Dr Ibrahim Beşikli Cd to find the main strip. Not all places provide air conditioning.
