The island of Ibiza comprises five municipalities: Eivissa, with almost 32,000 habitants, Santa Eulalia with about 20,000, San Antoni de Portmany with approximately 15,000, San Josep des Vedrà with 13,000 and Sant Juan de Labritja with 4,000.
In the old days, the island was divided into "quartons" and had not municipalities. The dispersion of the population made of the parish a vital unity which itself was divided into "vendes" that, with the utilisation of communal wells, they acted as an agglutinating point for the population.
This municipality with a surface of 11,1 km2, is the most populated point of the island and holds the industrial and administrative activity.
The third most important population point. The old quarter is formed by the Puig de Misa, an example of a fortress-city raised on the top of a hill, with a defence tower placed against the church and white houses in its surroundings. The new city in settled on the low quarter around the bay and the river, only 11 km long, the unique in the Balearic Islands and nowadays, almost dry.
The municipality of Santa Eulalia is made up of the villages of Sant Carlos de Peralta, Santa Gertrudis de Fruitera, Jesús and Puig den Valls. The last two have considerably grown and become important population areas but Sant Carles and Santa Getrudis are still small villages built around a church and keep their rural charm.
The municipality of Sant Antoni de Portmany is located in the north-east part of Ibiza island and has a surface of 124,5 km2. Besides its capital, it comprises the villages of Sant Rafel de Sa Creu, Santa Agnes de Corona, Buscastells and Sant Mateu d'Aubarca, all of them situated in the interior of the municipality. Sant Antoni de Portmany takes up, together with the municipality of Sant Josep de sa Talaia, the old "Quartó de Portmany".
Sant Antoni's port is connected with the peninsula -which is only 92 km away- and Majorca.
The southerner and biggest municipality of the island and the one with the largest number of beaches - one of them, the most crowded, Ses Salines- which belongs to the only Pitiüses Natural Reserve. It is made up of the villages of Sant Agustí des Vedrà, Sant Jordi de ses Salines and Sant Francesc. The highest mount of the island, "Sa Talaia"- 475m- is to be found here.
Located in the north-west part of the island, it comprises the villages of Sant Joan, Sant Miquel, Sant Vicent and Sant Llorenç.
In the coast, the cliffs alternate with small coves, being the most popular Sant Miquel port, made up of a deep beach protected from the wind. In the interior we will find mountains with a considerable height such as Puig Fornás - 409m- or Puig Gros - 403m-.
The municipality is surrounded by the Mala Costa mountain range.
We should highlight la Cala de Sant Vicente, Portinatx, Cala Xarraca, Cala Xuclà, Cala Benirrás or Es Portixol.
