Mallorca’s southwest is home to some of the most beautiful beaches on the island. Dotted with white sandy coves, the rocky coastline stretches for kilometres, as far as the eye can see. If you explore further, you’ll discover that beyond the limestone rocks lie a network of otherworldly caves waiting to be explored. Let’s dive into Mallorca’s geological history and some of the most spectacular caves near Ses Salines.
Rock on: a short history of caves
Most of Mallorca is composed of limestone, a sedimentary rock formed from the mineral calcium carbonate. Over the years, rainwater erodes and dissolves the rock, creating holes and passageways. As the water travels from the ceilings of the caves, the calcium carbonate forms mystical stalactites, which hang down, and stalagmites, which grow upwards from the cave floor. Mallorca’s oldest caves, like the Coves del Drach near Manacor and Hams Caves in Artà, are millions of years old and steeped in stories of dragons and hidden treasure.
Caves worth seeing: Cala des Marmols
Translating to “marble cove”, this secluded bay is one of the most idyllic on the island. You can reach it on foot—after a hike from Cap de Ses Salines lighthouse—or by boat. Upon arrival, you’ll be greeted by unique rock formations and turquoise water that sparkles. The beach is framed by limestone cliffs with spectacular arches and caves to explore. Some are said to have been used by smugglers, so look out for buried treasure. Top tip: there are no toilets or facilities so bring everything you need.
Protected Reserve: Marina del Migjorn caves
Located on the south coast, this is a protected area with underwater caves and precious biodiverse marine life. Snorkelling is allowed but scuba diving, fishing or feeding the fish are strictly forbidden—always check local regulations before making a trip. The reserve is home to coral reefs, different species of colourful fish and Posidonia oceanica meadows. A spectacular natural wonder.
Boat trip to Cabrera National Park
From Colònia Sant Jordi, take a boat out to the Cabrera archipelago not far from the island of Mallorca. On the north side, the Blue Cave, known as Cova Blava, is a great spot, especially in the afternoon when it is lit up by the sun. Explore the dramatic grottoes along the islands’ coastlines, plus it’s perfect for snorkelling too.
Stay safe on your cave adventure
Always be prepared. Check the weather forecast for rain, wind, tides and extreme heat. Wear suitable clothing: sturdy footwear for hiking and reef-safe sunscreen, plus any other protective gear for swimming and snorkelling. When visiting remote areas, always make sure you have plenty of water and food. Respect the natural world, stay safe and have fun.
