Cuevas del Drach (Dragon Caves)

The Cuevas del Drach (or Dragon Caves) were already known during the Middle Ages. These calcareous formations were formed between 11 and 5.3 million years ago, during the Miocene era. Between 1922 and 1935, they were conditioned to be visited by opening a new entrance, building paths, stairs and installing electric lighting. The tour takes about an hour and includes a classical music concert and a boat trip. The temperature inside is about 21°C and the humidity an 80%.

The colours and formations within the cave are truly astonishing and those with a creative imagination will see formations resembling a cactus, a flag and even a snowcapped mountain. There is also the Baths of Diana and a multitude of fantastic stalactites that grow 1cm every 100 years.

The tour ends with a floodlit, floating violin concert on Lake Martel, Europe's largest underground lake, about 170 metres long and between 4 and 12 metres deep. The lake is named after the French geologist Edouard Martel who first explored these caves in the late 19th century, at the commission of Archduke Ludwig Salvator. Afterwards you can return by boat across the lake to the exit.
