Swimtheisland Golfo dell'Isola is an open water swimming event at Spotorno, on the Golfo dell'Isola stage of the Swimtheisland circuit. It is part of the same series as the Sardinia San Teodoro and Lake Garda swims. The published information does not specify a fixed month or season. The event offers different race distances, with some listed as competitive and others open on a non-competitive basis.
The swim takes place within the protected marine area of Bergeggi. The route covers a stretch of coast with caves and well-known diving sites below the surface. Canalone, Pifferaio, and the Marine Cave of Punta Predani are named as notable underwater spots in the area. Participants may include swimmers pursuing a ranked race and others entering for the open-water experience, but everyone must have a valid medical certificate, accept the regulations, and confirm they are fit for the conditions.
