More than 200 cave systems have been found on Mallorca. Although most are not accessible to the public, some can be visited and provide a captivating glimpse into the island's secret world. Join a guided tour to explore ancient stalactites, unusual rock formations, and even underground lakes.

1) Cuevas del Drach (Dragon Caves)

Located in Porto Cristo, the Cuevas del Drach are perhaps the most famous of Mallorca’s caves, and for good reason. These expansive caves house one of the largest underground lakes in the world, Lake Martel. Visitors can enjoy a self-guided tour that finishes by a short classical music concert performed on boats. However, during peak season, the caves can feel like a subterranean rush hour with hordes of tourists packed into the narrow passages. If you don’t mind feeling like a sardine in an ancient can, the awe-inspiring sights are well worth it.

2) Cuevas del Hams

Also near Porto Cristo, the Cuevas del Hams (Caves of Fish Hooks) get their name from the unique hook-shaped formations found within. These caves, attracting a fraction of the crowds at the Cuevas del Drach, are famous for their colorful lighting and impressive stalactites. The tour includes a multimedia presentation with technicolor light show. However, some purists might find the artificial lighting a bit gimmicky. If you prefer your caves au naturel, this might not be your top pick, but it's definitely a hit with kids and those who enjoy a bit of flair.

3) Cuevas de Artà

Situated near the town of Canyamel, the Cuevas de Artà are known for their dramatic stalactites and stalagmites, some reaching heights of over 20 meters. The caverns are spacious and the guided tours are rich with historical anecdotes and geological facts.

4) Cuevas de Campanet

Nestled in the Tramuntana mountains, the Cuevas de Campanet are smaller and less commercialized than some of the other cave systems. These caves are celebrated for their delicate formations and the serene ambiance they provide. Don’t expect a grand underground concert or boat ride here. It’s just you, the rocks, and a lot of dripping water—sometimes right on your head.

5) Coves de Gènova

Located just a short drive from Palma, the Coves de Gènova are the smallest and least commercialized caves on the list. They offer a quick, but fascinating look at Mallorca’s underground beauty without the fanfare. However, their modest size means the tour is over almost as soon as it begins. Great for a quick detour but don’t plan your whole day around it.
