The caves of Drach are four large caves in Mallorca. They are located in the municipality of Manacor near the town of Porto Cristo. The caves extend to a depth of 25 m, reaching a length of 2.4 km.

The four caves, called Cueva Negra (Black Cave), Cueva Blanca (White Cave), Cueva de Luis Salvador (Luis Salvador Cave) and Cueva de los franceses (Frenchmen’s Cave), are connected to each other.

They are home to a large underground lake, called Lake Martel (Llac Martel), which is 115 m long and 30 m wide. In this lake, considered one of the largest underground lakes in the world, live classical music concerts are held every day. You can cross the lake by boat at the end of the concert.
