I saw that there was a tour operator going to Semipalatinsk Nuclear Test Site as a part of a tour of the former USSR, but it was lumped in with things like old prison camps and monuments. The tour was expensive and lasted about a week.
Is there any tour group that would take me directly there, possibly spend a night, and then head back? I'm short on time and would be fine with no more than 4 days in Kazakhstan.
Any experience with custom tours using Caravanistan? I think it's too far off to request a quote, but all the other places have outrageously priced tours and Caravanistan seems decent.
