I've been looking to go to Central Asia for a while, but flights from the UK to any of the 5 'stans (apart from Astana and Bishkek) are pretty expensive. So I figured that the most economical way to experience them all would be a single long multi-destination road trip. I don't know how viable such a trip is though and would like some advice. The only alternative that I can think of is to pay for tours, which are often very expensive and can feel more like being shepherded around than indepently exploring the country yourself.
In Kazakhstan, Kyrgyzstan and Tajikistan I'd like to see the vast landscapes and drive/trek to the various beautiful mountain lakes. In Uzbekistan and Turkmenistan I would like to see the ancient sites on the old Silk Road too.
I'm not sure if this is possible though, and I imagine that renting a car/cars might be difficult (especially cross-border) and possibly quite expensive given the vast distances.
I don't really have any qualms with driving for many hours at a time; I find that it's usually one of the best ways to see the natural beauty of a country, and I don't mind having to spend days/nights away from civilisation (I'd also like to experience the local nomadic culture if possible).
Anyway, does anyone here know if this kind of trip is feasible, and how I should go about budgeting it/planning an itinerary. Thanks in advance!
