Wealthy and densely populated.
Monaco is a tiny nation in the south of France where the wealthy keep their yachts and gamble. Unless you're rich, there's not much to do here except go to any of a number of viewpoints to take in this tiny city-state.
I spent a day in Monaco on my Global Cycling Tour. I received some glances from people and police officers downtown reminding me how out of place I was, with a tent on my bike and holes in my socks. I carried on, back into France.
