In 2010 I was driving round Central Asia in a camper with my fiancée, I had my kite gear with me despite it not exactly being renowned for kitesurfing, i managed a few pretty weird sessions and certainly entertained the locals.
1 - The Volga river, just north of Volgograd (http://goo.gl/maps/DVxM1
) and again near Samara (http://goo.gl/maps/WHRQY
) in Russia. Its about 500 - 800m wide with a moderate current, quite deep, but water was a bit smelly. Both were pretty sketchy launches inland and then a walk out to the river banks, good flat water but inland wind a bit flukey. Worked best in Samara where the wind was against the river current. Near Volgogard I couldn't stay upwind in the current so had to come inshore a way from where I was parked up, as I packed up the Russian police turned up and tried to fine me 100$ for not having a boat licence. Dripping wet I obviously had no money so they threatened to take my kite away until I paid, but as I hadn't deflated it yet I asked how they were going to fit it in their Lada, after about 40mins of stale mate they got board and left.
2 - In Siberia there were countless small shallow lakes that it tried on, below I remember especially as the water was so immensely saline that with a light wind board I could stand up with virtually no wind. http://goo.gl/maps/MmZDZ
3 - Lake Balkhash in Kazakhstan. Actually a beautifully kite spot, the lake water is super Turquoise and wind surprisingly consistent. Took some serious off road driving but when we found this remote peninsula we stayed for a week till our water ran out, I got a session in every day. Some local fishermen found us one day and were completely blown away to see kitesurfing, they came back that evening to share Vodka and some kind of huge unidentifiable salty fish. http://goo.gl/maps/mSYe5
