Susie Wolke’s travel map

Susie Wolke is a well-travelled explorer who has set foot in 31 countries across Asia, South America, Europe, Africa and North America. The visited countries are home to 32% of the world's population. Across 31 countries, 27 official languages are spoken — real linguistic diversity. The visited countries hold 527 UNESCO World Heritage Sites between them.

There's a clear soft spot for small nations — countries where the entire population could fit in a football stadium. Landlocked countries are no obstacle — more than five nations with no access to the sea have been explored.
