This is one of the most spectacular and preferred routes for hikers in the province of Valencia. A tour of caves and tunnels dug into rock, a Roman aqueduct and a wooden walkway through the coved in passage.
A route nearby the sea, starting from Simat de la Valldigna, with a mild ascent along Ruta del Agua, followed by a flat section in Mondúver range. At the end of this section there is a lookout point with excellent views of the sea and the famous mountains like El Montgó and, obviously, Mondúver. The final part of the route is the descent to the castle, which gives the name to the route.
