-Definitely. I had a tour there a couple of years ago, and the takeaway memory (in addition to the slightly eerie feeling of having been dropped into a massive Fallout game) was as we walked across a bridge over a small canal, I saw the biggest sturgeon-y fish I'd ever seen.

The guide shrugged and observed something along the lines of 'This is what happens when #2 in the food chain suddenly becomes #1.'

Considering the number of people who now go on Chernobyl tours, I am just waiting for the Lonely Planet crowd to label the place 'spoiled' ;)

Another amazing 'weird' nature reserve is the DMZ between South and North Korea. You can see the most amazing birds of prey there hunting animals in the area between the propaganda villages.
