Ibiza and Formentera turn the Balearics into a flexible local-operator dive trip: fly into Ibiza, dive deep wrecks and islets, then ferry to Formentera for Es Freus Marine Reserve arches, caves, and Posidonia meadows. The signature scuba mix is unusual for Europe: the Don Pedro wreck near Ibiza, beginner-friendly Dado Pequeno, La Bota off Es Vedra, and Formentera sites such as El Arco, La Mariana, Punta Gavina, and Punta Rasa Caves. Snorkelers get shallow turquoise coves, Ses Illetes, Cala Saona, Espalmador boat days, and seagrass-clear water. Freedivers find line training, caves, and sand-to-wall profiles, with apnea permitted in the reserve while spearfishing is not. Topside, Dalt Vila, Las Dalias, Ses Salines, cycling routes, sunset beaches, and excellent food make the islands easy for mixed groups.
