Cuevas del Drach

The Caves of Drach (modern Catalan spelling: Coves del Drac [ˈkɔβəz ðəl ˈdɾak]; Spanish: Cuevas del Drach; lit.

'Dragon caves') are four great caves that are located in the island of Majorca, Balearic Islands, Spain,[1] extending to a depth of 25 m and reaching approximately 4 km in length.

The caves have formed by water being forced through the entrance from the Mediterranean Sea, and some researchers think the formation may date back to the Miocene Epoch.

[3] The caves are open to the public for a fee, and are one of the main tourist attractions on Mallorca.

[4] The caves are such an integral part of the tourism industry, that its closure, even if temporary, is seen by the locals as a bad sign for the economy.
