The experience is located in the province of Castellón, an area where I have lived since my childhood and I enjoy it whenever I can! In a matter of minutes we will delve into the antiquity of the civilization where people and wild animals lived more than 17,000 years ago. I'm talking about the Sant Josep Caves, a wonderful natural site hidden inside an immense cave with a route that is partly on foot and partly by boat. It is the largest underground river in Europe, very little known and a spectacle for the senses. I invite you to enjoy this unforgettable experience that will not go unnoticed. We will leave from Valencia (maximum 4 people) traveling by car for approximately 40 minutes to the town of La Vall D'uixo (Castellón). Once there we will begin the tour inside the cave that will last about 40 minutes at a constant temperature of 20 °. The route consists of 800 meters by boat and 250 meters on foot. There is no risk or dangerous situation during the visit. Dare to enjoy something different and special. Feel the sensation that time has stopped in a very special atmosphere. At the end of the visit we will return to Valencia to the starting point
