The Baja California peninsula is divided into two states, with the southern portion called Baja California Sur (south). The northern state is simply called Baja California. In 1971 Baja California Sur became the 31st state, and it's capital is La Paz. The southern state is well known for its resort areas, the most well known probably being Cabo San Lucas.

And because of it's location, there are still miles of undeveloped coastline. And because of this, and its proximity to the southwest United States, it has become a popular get away for many people.
