Ashgabat
There is no place like it in the world; wide boulevards, marble skyscrapers, unique and strange monuments, and an eerie lack of people during the day. Make sure you take one day for monuments sightseeing only. There is a big number of them all over the town and they are quite compelling. Don't miss the world's largest enclosed ferris wheel and the Monument to Neutrality. Basically, wherever you turn, there will be something unusual and unexpected. Ashgabat is a real treat.
