It was raining first thing so we opted for an outing to Guadalest to see the castle, which was great but which gradually became more and more crowded with visitors. We went back to the car, ate our lunch that we'd made up from the breakfast buffet, and drove down to the reservoir for a bit of a walk. 

We'd almost finished walking when we spotted a group of youngsters under the pine trees, and then we noticed the slackline strung out across an inlet of the reservoir. We spent ages watching two young men walking, bouncing and somersaulting, often falling off but easily righting themselves. It was mesmerising! The photo quality isn't brilliant but it gives you an idea.
