Salt Sea Water Pools, Madeira.
This place appears like a real paradise on earth: an extraordinary pool made up of volcanic rocks and little man-made maintenance works in order to make the place more comfortable and safe for visitors.
Going there you will enjoy a fantastic warm bath (remember that you are bathing in the Ocean!) and a majestic view of the north-west part of the island.
