Binisues - Menorca Natural Science Museum and Manor House

If you’re looking for something a little different to add to your itinerary in Menorca, Cova de S’Aigua is worth considering. Located near Cala Blanca, just outside Ciutadella, this underground cave of about 2500m² offers a guided experience focused on geology, water systems, and the historical use of natural resources.

It’s not a long visit, but it’s a good option if you want to include a mix of indoor and outdoor activities while exploring the island.

What is Cova de S’Aigua?

Cova de s’Aigua is a natural cave system on the west coast of Menorca. It features a series of underground chambers with rock formations, as well as a freshwater lake that has historically been used as a water source.

The cave has been adapted for visitors with walkways and lighting, making it accessible while maintaining its natural structure. Visits are typically guided, which means you’ll follow a set route and receive explanations along the way about how the cave formed and how it has been used over time.

What to Expect Inside the Cave

Once inside Cova de s’Aigua, the experience follows a steady, guided path through different sections of the cave. The environment is enclosed and cooler than outside, with lighting used to highlight key features.

You’ll see stalactites and other mineral formations that have developed over long periods. The cave isn’t overly large, but there’s enough variety in the formations to keep it interesting as you move through.

One of the main features is the underground freshwater lake. It’s calm and still, and the reflections from the cave ceiling and lighting are noticeable as you pass through this section. The lake has played a role in the cave’s historical use, particularly as a water source.

The visit is more about observation than activity. There’s no climbing or difficult terrain, but there are some uneven surfaces and steps along the route.

Cova de s’Aigua has been used in different ways over time, mainly linked to its freshwater supply. In periods when water access was limited, the underground lake provided a reliable source.

During the visit, guides usually explain how the cave was used historically and how it fits into the wider context of water management on the island. It’s not a heavily detailed historical site, but it does add some context to what you’re seeing.
