Drach Caves
Porto Cristo,
Spain
The Drach Caves are four large caves located on the Spanish island of Mallorca, in the Balearic Islands. They are situated in the municipality of Manacor, near the town of Porto Cristo, where the Hams Caves are also located. The caves are open to the public year-round. They extend to a depth of 25 meters and have a length of 1.2 kilometers.
The four caves, named the Black Cave (Cova Negra), White Cave (Cova Blanca), Luis Salvador Cave (Cova de Lluís Salvador), and French Cave (Cova dels Francesos), are interconnected. The caves have been formed by the action of rainwater, and some scholars believe that their formation dates back to the Miocene, between 11 and 5.3 million years ago.
