1. Almería: Caves of Sorbas Tour
Walk, climb and crawl the galleries of the gypsum mineral natural cave in Sorbas and admire the reflection of crystals when they receive the light from your helmet. Marvel the effect water erosion and the passage of time have had on the plaster rock. Explore the Yeso Cave with a specialized guide. The Barranco del Infierno Cave, as it is also known, was formed thousands of years ago and was the first cave complex to be discovered. See first-hand the effect of water on the shaping of rocks. The underground karst system of Sorbas collects rain and floodwater and drains it through the galleries.
