Beijing, China and Badaling (for the Great Wall)
Hawaii - the Big Island

are probably the most "exotic" places I've been by most people's standards. But I've also visited London and the wilds of Glasgow, Scotland, and lotsa places on the mainland US as well.

I will admit to stopping by likely-looking swamps in Florida and calling for alligators, but I never got to see one, despite driving places where people assured me "they lay right across the road there, it's a real nuisance."
