What Is the Aquatic Caving Experience in Sumidero de Vallada?

This tour offers a peek into the hidden world beneath the earth’s surface in one of the most fascinating gypsum caves on the planet. The Sumidero de Vallada is renowned for its depth (about 1300 meters long) and significant elevation drop (205 meters), which contribute to its status as the deepest gypsum cavity worldwide. Over millions of years, water has shaped the cavern’s stunning formations, evident in the geomorphology that visitors can observe during the tour.
