Isla del Sec is a small island off Mallorca's southwest coast with three small wrecks on the seabed around it: a boat at 18 m with boxes, mast and deck plan still recognisable, and two more at about 27 m, with the site's maximum given as 32 m. It is listed for all levels from Open Water upwards, and the rock around the boats carries groupers, octopus, moray eels, barracuda, scorpionfish and several kinds of bream.
Also known as Illa del Sec, Isla el Sec.

The dive
The first stop is the small boat at 18 m. Enough of it is intact to read as a vessel rather than debris: boxes, the mast and the ship plan are all still clearly recognisable, and it is the shallowest and the most complete of the three. Circle it slowly, checking under the structure for the octopus and moray eels both operators list, and keep an eye on the water above for barracuda.
From there the profile can go deeper to the two other boats, which lie at approximately 27 m, with the site's stated maximum at 32 m. That puts them at the deep end of a recreational dive, so they are a shorter visit before working back up over the rock. The bottom around the wrecks is big rocks with small corals on them, with different types of bream over them and scorpionfish tucked into the rock; the operators' lists agree on groupers, octopus, moray eels and barracuda, and the site is described as very varied and suitable for every level.
