I only got to know a very small piece of Kazakhstan so my observation regard the road between Kyrgyz border and Almaty.
Visa
You can stay for 30 days without visa.
Border crossings
Kyrgyzstan – Kazakhstan: (Karkara) All you have to do is to get your entry stamp.
Kazakhstan: (Almaty – airport) Everything goes like everywhere in the world. You just get a departure stamp in the passport.
– Main roads are quite OK.
– ATM’s exist only in bigger towns.
– You can easily communicate in Russian.
– Kazakh drivers seem to drive more carefully than their neighbours.
– Roadside shops offer a wider range of products than in other post-Soviet republics.
– The Internet isn’t flawless.
– There are almost no dogs.
– Sharyn Canyon: You have to pay an entrance fee at the gate (around 750 tenge). You can camp for free. You can also rent a yurt or a bungalow. There’s a restaurant where you can eat but prices are higher than in other places.
