The tiny island of Formentera covers 35 square miles (90 sq km) and is home to just over 5,000 people. It can be reached by ferry from Ibiza town, with a regular service running every two hours. Recently ferry services to Formentera from the mainland have also been established, due to the island's increasing popularity. The island is a popular day trip from Ibiza, and is relatively unspoilt by tourism development, although it is not as empty of crowds as it once was. Accommodation options are very limited. The main attractions on this flat piece of land are some pretty villages and marvellous beaches flanked by palms and pines, many frequented by nudists. The best way to explore it is on a rented moped, or on a bicycle, as there are well-maintained cycling tracks traversing the island. The main port is La Sabina, and the other villages include beautiful Las Salinas, San Francisco Javier and San Fernando, all featuring quaint white-washed houses. Recommended beaches are Es Pujols in the north, Mitjorn in the south, and Cala Saona in the west. Other beaches of note are En Boster, Ca'n Xico Mateu and the natural port of Es Calo. The highest point on the island is in the southeast corner at El Mirador.
