La Esponja
A reserve dive to 28 m, with the route cut to fit the group

A dive inside the Es Freus marine reserve, where the plan is cut to the group rather than the other way round: the site bottoms out at 28 metres but is dived at every level. Groups of barracuda and small tuna hunt over it, often on shoals of smaller fish, while moray eels, conger eels, lobsters, crabs and nudibranchs hold the rock.

The dive
La Esponja sits inside the Es Freus marine reserve. Its maximum depth is 28 metres, but that is a ceiling rather than a plan: the itinerary is chosen depending on the level of the divers, so the same site gives a shallow, long dive to one group and a deeper, shorter one to the next, and the depth you end up at is a decision made on the boat.
The dive is as much about the hunting as the rock. Groups of barracuda and small tuna work over the site, often on shoals of smaller fish, and when that is happening the dive is spent watching rather than swimming. In the rock itself there are moray eels and conger eels, different types of lobster and crab, and several kinds of nudibranch and anemone for anyone looking closely.
