More than 100,000 years old and once used by smugglers to store contraband, the Can Marça caves are now one of the most visited attractions on the island. Artfully illuminated, this colorful subterranean world is silent and cool, with beautiful stalactites and stalagmites formations dripping from the ceiling and a stunning 30-foot water fall, accentuated by a breathtaking music and light show. Multilingual guided visits take place daily, year round.
