There's a woman that made an kinda online tour of it. KIDDofSPEED - GHOST TOWN - Chernobyl Pictures - Kidofspeed - Elena
The first Chernobyl trip is the link labeled "beginning." I listed the homepage because she has a few different interesting ones. I recommend The Serpent's Wall. It's the story of the WWII bunkers and battle sites around Kiev.
There's a documentary called The Battle of Chernobyl that's really good, and free to watch online. It's about the clean up, those guys were heroes that deserve a lot more recognition.
