Unlike most people at MostTraveledPeople.com I do not collect countries per se. My focus is another list: my aim is to visit all entries on Unesco's World Heritage List!
It all got serious in 1997 when I built a website around this theme. To keep its content interesting I just had to visit more and more World Heritage Sites all over the world. Currently I'm on 319 visited WHS in 141 different MTP places. A lot of WHS are quite remote and quirky, and I love to travel to some distant part of a country to just see a mine or some rock carvings. It really gets you off the beaten track.
My Favorite Places:
Kathmandu Valley (Nepal), Angkor (Cambodia), Rila Monastery (Bulgaria), Easter Island (Chile), Yungang Grottoes (China), Chaco Culture (USA), Iulissat Icefjord (Greenland), Orkhon Vally (Mongolia), Ouro Preto (Brazil), Salta and Jujuy (Argentina), Zanzibar and many more.
