visit all the places on the Unesco world's heritage list

United States
Mammoth Cave National Park (1981)
Great Smoky Mountains National Park (1983)

France
Palace and Park of Versailles (1979)
Cathedral of Notre-Dame (1991)
Paris, Banks of the Seine (1991)
Belfries of Belgium and France (1999, 2005)

This is kind of pathetic considering that I live in the U.S. but I guess the sites on the UNESCO list aren’t necessarily the top tourists spots. But now that I am more familiar with it I am definitely going to make sure to see the places on the list whenever I go anywhere.
