The highlight is a crystal-clear cave filled with colourful stalagmites, accessible via a short swim through a water entrance. Key Details Duration: 6 hours Location: Cala Romàntica, Mallorca Level: Suitable for beginners and families Minimum Age: 12+ What to Expect Your day begins with a scenic 40-minute walk along the cliffs above Cala Romàntica, providing expansive views of the eastern coastline. On reaching the beach, you’ll change into wetsuits, put on provided water shoes, and swim approximately 300 metres to the cave entrance. A short duck under the water leads you into the cave’s interior. Inside, you’ll navigate a network of large, cathedral-like chambers and underground pools illuminated by headlamps. The striking red stalagmites reflect mineral deposits influenced by the sea, and your guide will explain the geology and history of the cave. Around an hour is spent exploring this natural formation. If sea conditions prevent access, the guide will lead you to two alternative caves nearby, one with water features, ensuring a memorable day. After the exploration, swim back to the beach and return along the coastal path. Location The tour is based at Cala Romàntica, home to one of the finest beaches on Mallorca. Its calm, clear waters and golden sand make it ideal for relaxing after the cave adventure. Visitors can spend time unwinding on the beach or taking in the dramatic coastline. The area is also known for its seafood restaurants, offering freshly caught fish and other local dishes with views over the coast. This combination of adventure and leisure makes Cala Romàntica a perfect location for a full day of exploration and relaxation.
