Cabo Polonio is an interesting place in Uruguay. It doesn't have electricity, so the shops there use a generator for the most crucial things, and fridges run on gas. At night the Milky Way can be clearly seen, as there is almost no light pollution. During the day, people just enjoy the beach, the gigantic dunes nearby or take a surfboard out.
To enter Cabo Polonio, you either need permission and a good four wheel drive, or you take one of the trucks. Most people take the trucks, which results in a village where there are almost no cars.
Originally, Cabo Polonio was a fishermen's village. Although nowadays the biggest source of income for Cabo Polonio is tourism, fishing is still practiced. The boats they use to go out on the ocean to fish are quite small.
