Portugal offers some of Europe’s most accessible and surprisingly diverse snorkeling spots. Its rugged coastline, protected marine areas, and warm waters create ideal conditions for underwater exploration. We particularly like the Snorkeling Tour in Porto Santo because it combines a scenic coastal setting with abundant wildlife, including octopus and starfish, in a calm lagoon. For a different kind of thrill, the Night Snorkeling Tour reveals the ocean’s nocturnal life, making it a memorable experience for night owls and curious explorers alike. And for those heading to the Azores, exploring caves and waterfalls on Flores or swimming with dolphins on Terceira provides a chance to see Portugal’s marine biodiversity in all its glory.
