This place comprises a group of islets to the west of Ibiza, as well as the surface and the seabed that surrounds them. There are a total of six large islets and a dozen or so smaller islets and reefs. The most important islets, from largest to smallest, are Conillera, Espartar, Bosc, Na Plana, Na Bosc and Na Gorra, the last three belonging to the Ses Bledes group. The interest and scenic attraction of this place are very high since these islets, which are heterogeneous in appearance and quite prominent, form a sub-archipelago in the northwestern sector of Ibiza, which is very visible from different points along the coast. The intrinsic visual quality of this ensemble, as well as that of its immediate surroundings, is of great importance.
