Potholes (Italian "Marmitte dei Giganti") inside the Regional Park of Alpi Apuane, Tuscany, Italy. These amazing geological structures are very difficult to explore since they are located in a remote region under the south face of Mount Sumbra( in the bed of "Anguillara river") and require alpinistic skills and a good dose of adventure to reach them.
