The Piscinas Naturais do Aquário, are a set of free, natural pools located in Porto Moniz on the north coast of the island of Madeira. These pools are particularly unique because they are formed by volcanic rocks and filled with saltwater from the Atlantic Ocean, offering visitors a picturesque and untouched setting for swimming.

There is no admission fee to access these pools, and they are known for their clear and pristine waters, providing a refreshing experience amidst the stunning contrast of colors from the blue sky, white clouds, and the darker blue sea against the black lava coastline. While the Piscinas Naturais do Aquário do not have support infrastructures or sanitary facilities, there is an outdoor shower available, and the area is supervised during the bathing season.

It’s a place of natural beauty and tranquility, perfect for those looking to enjoy a swim in a unique and scenic environment.
