During our Spain trip this past spring Darlene put together a day trip for a friend and me. All we knew of this place was what I could find on the internet. The online brochures said it was about a 7-to-8-kilometer hike. I would say that estimate is a little low. We had a bit of a rough start, but it turned out to be a great hiking adventure. Nothing real tough as far as hiking goes. I would highly recommend this adventure... unless you're afraid of heights, because there were a few of those. I would do this one again...
