https://chernobyl-tours.co.uk/. It is the official tour operator for foreigners visiting the Chernobyl zone, and everything is organised at a high level — transfer, translation, guide services. I went there myself last summer, and it was one of the most memorable trips of my life. Seeing Pripyat, the sarcophagus over the reactor, and feeling the silence of this place is an experience you will never forget. Ukraine has an incredible history, and this tour helps you understand it better than any book.
