El Desfiladero de Despeñaperros

On our trip south from Madrid to Granada on the A4, we wound our way through the spectacular Sierra Morena mountains over a pass called El Desfiladero de Despeñaperros. A new super highway was being built to enable cars to fly almost straight through the pass and the view will probably be fantastic, but there's something nice about cruising the slower switchbacks and taking in the changing landscape. On the other hand, maybe the new highway will make the slow road into a great bike route.
