The famous Del Drach caves are located in the municipality of Manacor, near the town of Porto Cristo. They are a true sight to see; visitors can enjoy 1,200 meters of tunnels and even a classical music concert.

Known for their great archaeological value, they offer a variety of formations hanging from the ceiling, called stalactites and others born from the ground, called stalagmites.

Its four main caves are called Black Cave, White Cave, Luis Salvador Cave, and the Cave of the Frenchmen, and are inter-connected. The caves were formed by the water from the Mediterranean Sea, and some specialists affirm that its formation could be traced back to the Mycenaean period. Over time, water leaks shaped the formations inside, composed of calcium carbonate along with minerals washed down from the surface, giving them subtle differences in their colouring.

But undoubtedly, the main attraction within these cavities is its large underground lake, called Llac Martel (Martel Lake), approximately 115 metres long and 30 metres wide. Daily classical music concerts are offered and visitors can also cross the lake by boat at the end of the concert.
