Southern California: land of movie moguls and big celebrities, Spanish missionaries and military heroes. It's a region full of character, from the people it has attracted over the centuries to the natural wonders that make up the Golden State's lower half. Join us as we soar above towering mountains of sand, race across a valley that's also the hottest place on Earth, and discover volcanic craters that are nothing short of otherworldly as we celebrate the sites, stories and spirit of this land of extremes.
