A quirky, solitary tree that has found a place to root here and is successfully holding on to the slope. Coming from the south, you have already covered most of the way to the Ojos del Diablo, but a final steep climb still awaits.

The view through the devil's eye onto the coast at Sonabia is breathtakingly beautiful and rewards the strenuous journey here. The stone arch can be reached either via the coastal path between Sonabia and Villanueva or, less spectacularly, through the mountains to the south from a parking lot near the A8. An absolute postcard motif!
