The roads going to and coming from the gorge were very narrow. We had to stop often for cars to pass us going in the other direction. It was a very hilly drive, too. When we reached the top of the last hill, we had wonderful views of three reservoirs. Quoting from Simon's brochure: "Spain is a dry country, and water is a scarce resource. It also becomes a political issue as different Comunidades argue about how much water can be taken out of one river and channelled to another. The typical case cited is of farmers in Aragón complaining about their water being taken to water golf courses in Murcia. Drought is a frequent phemomenon. Many rivers only have water in certain seasons, and it is not uncommon to cross a dry water course with only the sign to indicate that there is a river there from time to time. During the last drought in 2008, container ships were being brought into Barcelona to supply the city with water. It is not uncommon to see reservoris which are virtually empty. Many areas of the country are actually desert. The most striking examples are those of the Bardenas Reales in Navarra, and also the Desert of Tabernas in Almería, Andalusia. The so-called spaghetti westerns (The Good, The Bad and The Ugly, and For A Fistful of Dollars) were filmed here, as well as parts of Lawrence of Arabia, and it is still possible to visit the film sets there our in the desert and take a horse ride around a Wild West village while cowboys stage gunfights".
