The area is accessible with a tour company only. You need a special warrant from the government to be let in the Zone. The tour company will arrange that for you. Don't go on your own. Even if you managed to get the warrant and get in, while it's safe in most places of the city of Pripyat, wandering around without a guide is extremely risky.
The prices start at around 130 USD
