Isla Grosa is an island in the Mediterranean Sea, belonging to the municipality of San Javier in the Region of Murcia, at a distance of 2.5 km from the northern part of La Manga del Mar Menor.

[3] The island has unique plant communities made up mainly of cambron (Lycium intricatum), oroval (Withania frutescens) and some nitrophilous species such as sosas.

[1] The existence of a rock, called "Bajo la Campana" to the east of the stack, a few meters from the surface, constituted for centuries a danger to navigation.

All the cargo of this ship and the rest of the wrecks discovered under the waters of Isla Grosa are currently on display at the National Museum of Subaquatic Archaeology in Cartagena.

[7] The island was a military zone until the year 2000 and was used as a training site for the special units of combat divers and explosives deactivation of the Navy's Diving Center.
