description Furnas do Cavalum Overview
Furnas do Cavalum is a significant lava tube complex located on the Portuguese island of Madeira, specifically within the municipality of Machico. The site consists of an extensive underground network of tunnels and passages formed by ancient basaltic lava flows. During the volcanic eruptions, the surface lava cooled while the hotter interior continued to flow, eventually leaving these hollow geological structures behind. The complex remains an important natural feature for understanding the volcanic history of the Madeira archipelago.
