Caves of Drach Tour — Classical Music on Underground Lake Martel

Why the Caves of Drach Are Mallorca’s Most Unmissable Experience

Beneath the sunlit east coast of Mallorca, at a place called Porto Cristo, lies one of the most dramatic natural spectacles in all of Europe. The Caves of Drach — Coves del Drac in Catalan — are a network of four connected cave chambers stretching hundreds of metres into the limestone bedrock of the island, and at their heart sits something almost impossible to believe until you’ve seen it: Lake Martel, one of the world’s largest accessible underground lakes.

At 177 metres long and up to 30 metres wide, Lake Martel glitters in the carefully placed cave lighting like a mirror held underground. And at the centre of every guided tour, musicians in traditional dress board illuminated boats and drift across its surface playing live classical music — Chopin, Handel, Bach — while visitors watch from the surrounding rock banks in near-total silence. It is one of those rare travel experiences where photographs cannot do justice to the reality.

A Journey Into the Earth

The caves themselves were known to local fishermen for centuries, but it was the French geologist Édouard-Alfred Martel who mapped them scientifically in 1896 — and for whom the underground lake is named. Their commercial development in the 1930s brought electric lighting and the first concert performances, a tradition that continues unchanged to this day.

Walking into the caves, visitors descend through the Lluís Salvador chamber (named for Archduke Ludwig Salvator of Austria, who first promoted the caves to the wider world) into a succession of galleries adorned with stalactites and stalagmites formed over millions of years. Some formations drip into perfect mirror pools; others have been shaped by air currents into curtain-like sheets of calcite. The temperature inside stays constant at around 18–21°C year-round — refreshingly cool in summer, slightly chilly in winter.

The guided walk covers approximately 1.2 kilometres of lit pathways before arriving at the lakeside amphitheatre for the concert. After the performance, visitors board boats for a short ride across Lake Martel, passing through the cave’s lower galleries before emerging on the other side. It is a genuinely theatrical experience, and one reason the caves draw well over a million visitors annually.

Caves of Drach vs Caves of Hams: Understanding Your Options

Mallorca’s east coast has two world-class cave systems within just two kilometres of each other, and first-time visitors often wonder which to choose — or whether to visit both.

Caves of Drach are the headline attraction: larger, more dramatic, and famous for the Lake Martel concert. The cave system is more extensive, and the combination of the walk, the music, and the boat ride makes it a complete 90-minute experience. It draws larger crowds, particularly in summer, so booking a guided tour with a set entry time is strongly recommended.

Caves of Hams — Coves del Hams — are smaller but no less beautiful. Known especially for their extraordinary stalactite formations and the reflective underground pools they call the “Sea of Venice,” the Hams caves tend to be quieter and are particularly popular with families and photography enthusiasts. The formation density is exceptional, and the lighting allows for truly striking images.

Many visitors find both caves equally rewarding and choose to combine them in a full-day tour: morning at the Caves of Hams, afternoon at the Caves of Drach, with time in the charming fishing village of Porto Cristo in between.

Choosing the Right Tour

The most popular approach is a half-day guided tour from your resort or hotel — coaches depart from all major areas of Mallorca including Palma, Alcúdia, Cala d’Or, and Cala Millor, making the journey simple regardless of where you’re staying. These tours include hotel pickup, the cave entrance, the concert and boat ride, and return transport.

For visitors based in Palma, the Palma: Caves of Drach tour with concert and boat trip runs directly to the caves and back in half a day. For those staying in the north, the Alcúdia: Caves of Drach tour picks up from all major north coast resorts.

For a more premium experience, small-group VIP tours combine the Caves of Drach with a visit to the dramatic cove of Caló des Moro, one of the island’s most photographed beaches. These tours cap at small group sizes and include a local guide with expert knowledge of both the geological and cultural history of the caves.

Practical Information Before You Book

The Caves of Drach are in Porto Cristo, on Mallorca’s east coast — approximately 65 km from Palma by road (about 55 minutes). Most visitors book guided tours that handle all transport; those driving independently will find parking directly at the cave entrance, though spaces fill up quickly in July and August.

Cave visits are timed, with entry sessions at regular intervals throughout the day. The concert and boat ride are included in every entrance, making the entry ticket alone — or a basic guided tour — excellent value for a full 90-minute underground experience. Booking in advance is strongly recommended in peak season (June–September).

The Caves of Drach are accessible to visitors of most mobility levels: the pathways are paved and relatively even, though there are some steps. The boat ride requires the ability to board a small craft. Children enjoy the experience from around age 3 upwards, and the quiet atmosphere of the concert tends to enchant even younger visitors.
