For tourists access to the country can be rather difficult government officials can complicate things beyond reasonable measure. Things can still happen to you that are present in the books of great ex-soviet literature that described the corruption of government institutions and government workers.
This is however not applicable to everyone but certain individuals can ruin your business trip or holidays.
Belarus has a rich and vivid history heritage that is tightly connected with Soviet Union. This can also be seen in the architecture of the country that is luckily very well preserved in many cities. Most damaged was done in the time of Second World War.
Except in bigger cities like capital Minsk, Brest, Mogilev, Gomel and Grodno, much of the country is uninhabited with lush nature and great spots for hiking, canoeing and horse riding. For western terms, Belarus is quite cheap except some nightclubs. Really worth visiting are the many museums and a pallet of orthodox cathedrals.
Belarus is an amazing place for any history enthusiast because there are many statues, monuments, cathedrals, old buildings that are deeply connected with Belarusian history and even some places like Njasvizh which is a UNESCO heritage site.
