Hitchhiking in Kazakstan isn't predictable. You can get 4-day rides with trucks or just rides of a few kilometers to the next village. People often offer rides out of cities when they see you walking.
The road between Aktobe and [[Aralsk]] is terrible! Trucks get stuck in the mud all the time. Going into [[Almaty]] you will often get dropped off at a big truck area about 10 km South of the actual city, so if its it's possible wait it out for a car when you get close to [[Almaty]].
People are sometimes asked for money, especially around the Chinese border.
