Cuevas del Drach: Exploring Mallorca's Dragon Caves

Updated: February 2025 Reading time: 8 min Region: Balearic Islands

Tucked along the eastern coast of Mallorca near the town of Porto Cristo, the Cuevas del Drach, or Dragon Caves, have fascinated visitors for centuries. This network of four interconnected limestone chambers extends more than 1,200 metres underground and shelters one of the largest subterranean lakes on the continent. The caves are not only a geological marvel but also a cultural landmark, hosting daily classical music performances that draw hundreds of thousands of visitors every year.

History and Discovery

The existence of the caves has been known since the Middle Ages, with references appearing in documents from as early as the 14th century. However, their full extent was not understood until 1896, when French speleologist Edouard-Alfred Martel was commissioned by Archduke Ludwig Salvator of Austria to conduct a thorough exploration.

Martel's expedition revealed the breathtaking underground lake that now bears his name. His detailed mapping of the cave system laid the foundation for the tourist experience that would follow decades later. By the early 1920s, the caves were opened to the public with electric lighting and walkways, making them one of Spain's earliest show caves.

The Four Chambers

The cave system is divided into four main chambers, each with distinct geological characteristics:

Lake Martel and the Concert

The undisputed highlight of any visit to the Cuevas del Drach is reaching Lake Martel. Measuring approximately 115 metres long and 30 metres wide, with a maximum depth of around 12 metres, it is one of the largest underground lakes accessible to tourists anywhere in the world.

What makes the experience truly singular is the live classical music concert performed on small boats that drift across the lake's surface. As the lights dim, musicians playing violin, cello, and keyboard glide silently through the darkness, their notes reverberating off the cavern walls. The acoustics produced by the natural stone amphitheatre are exceptional, creating an atmosphere that many visitors describe as deeply moving.
