The last paradise in the Mediterranean Sea is also called Formentera. The island belongs to the island group of Illes Balears, Mallorca, Menorca, Ibiza and Formentera. Formentera is the smallest island of the four and is a quarter of a mile away from Ibiza. It is also not accessible by plane, so you have to do so via Ibiza. Almost nowhere in Europe is the water is more blue and the sand is more white. This is because around Formentera the highest concentration of Posidonia Oceanica sea grass is found throughout the Mediterranean. These water plants provide a rich underwater life, with beautiful fish, coral and beautiful beaches and clear waters!
