Crossing this micro-state is no major sporting feat but the hilly winding streets make sure that it’s counted. With a total area of just over 2 square kilometres, you will have seen most of it just by entering it. Famous for its Monte Carlo Casino and its Formula 1 Gran Prix, it is also the state with the highest per capita GDP as well as the highest population density.
Perched up on the “Rocher de Monaco”, the old town, fortress and palace are the main tourist attractions as well as the two harbours either side of it packed with yachts each more extravagant than the last.
