Say, since Donkey Kong Country 3: Dixie Kong's Double Trouble!'s overworld, the Northern Kremisphere, was based on Europe, I saw a some similarities on my holiday to France.
Lake Orangatanga - Lac de Ste Croix
A few years ago I went on holiday to Bauduen, France with my parents and some friends. Near us was a lake named Lac de Ste Croix. In person it really bears a lot of resemblance to the lake levels of Donkey Kong Country 3. Well, a lot is an understatement - it is nearly identical, save for the lack of boardwalks. I almost expected running into some Kremlings there.... None of that however - instead I, random as it may seem, ran into one of my classmates. Heh!
My apologies for this short post. I will post more like these similarities once I see some.
