The lake's intense green color is caused by the high concentration of minerals leaching from the surrounding bauxite deposits.
Bauxite extracted here was primarily used for the production of aluminum.
The site is part of the Otranto-Leuca Coastal Natural Park, a protected coastal area.
The crater formation creates a microclimate that supports flora species distinct from the surrounding coastal plains.
Mining activities ended abruptly in the 1970s, leaving behind heavy machinery remnants that have since been removed or weathered away.
Laghetto Cave di Bauxite is a former open-pit mining site characterized by vibrant, copper-red soil contrasting with a deep emerald-green lake. The site ceased bauxite extraction operations in 1976, leading to natural groundwater flooding that created the current pond. The unique coloration results from the oxidation of iron-rich mineral deposits within the limestone quarry walls. The surrounding terrain consists of Mediterranean scrubland and wild orchids typical of the Salento region. Visitors traverse a network of unpaved trails that descend into the crater basin. The site is located approximately 2 kilometers south of the town of Otranto. It is a fragile ecosystem, and visitors are encouraged to stick to marked paths to prevent soil erosion. Geologically, it serves as a prominent example of post-industrial landscape reclamation through natural rewilding.
The ridge overlooking the crater offers the best panoramic view of the lake's green water against the red walls.
Wear sturdy, closed-toe footwear suitable for loose, rocky, and dusty terrain.
Carry plenty of water and sun protection, as there is minimal natural shade within the quarry floor.
Visit during weekdays to avoid crowds, as the narrow trails can become congested on weekends.
Do not attempt to swim in the lake, as the water is heavily mineralized and potential sediment instability poses safety risks.
Stay on marked trails to protect the fragile ecosystem and avoid trampling the native vegetation.
