I thought he had made a mistake too because the only Sierra Nevada I knew of is the one on the California-Nevada border.
dwfgator reminded me of the 6-part tv series Spectacular Spain with Alex Polizzi because I posted a link to it in response to a comment about Barcelona. That link has expired but the series is still on Youtube. Here is a link to one of the episodes that not only covers the Sierra Nevada, it shows the desert, Spaghetti Westerns, Moorish architecture at its finest and the city that is our provincial capital, the place where all your bureaucratic nightmares come true :-)
