Diving in Ibiza

Four coastlines wrap a small island, each with a different underwater character. The west reaches Ses Bledes, where the best-preserved gorgonian population in the western Mediterranean grows from 23m down to 60m. The south holds the Don Pedro, a 142m cargo ferry that struck Dado Pequeno rock in 2007 and now lies on its starboard side at 26-47m, one of the Mediterranean's largest diveable wrecks. East of Ibiza Town, La Catedral at Cala Llonga opens into an air chamber above the waterline with stalactites. The north around Portinatx is small-ensemble diving: grottoes, swim-throughs, and backlit cave exits fused in what local divers describe as electric blue.

Dado Pequeno, the rock that sank the Don Pedro, doubles as the island's richest site for large fauna. Close by, La Plataforma is a sunken fish-farm vessel whose twisted iron structures have colonised into what experienced local divers describe as "a mythical submerged city". Divers who compare Ses Bledes with the Mediterranean's other gorgonian coasts consistently rank it alongside Cabo de Palos and the Medes, with fewer boats on the water. Between the signature dives sit more than thirty named points spread across the four zones, plus shallow Posidonia meadows between Ibiza and Formentera that hold UNESCO World Heritage status. Treat the island as compact. Thirty minutes by car switches your dive zone entirely.

Shoulder seasons deliver the best conditions. May-June and September-October combine 19-24C water, 15-30m visibility, and lighter traffic than July-August, when the island itself turns expensive and noisy even before you reach the boat. A car rental opens all four zones from any base. Typical boat operations depart 09:00-09:30 and return by 13:30, running two dives per outing.

Advance booking is essential in August. For the Don Pedro wreck, carry Nitrox certification or obtain it on arrival; Scuba Ibiza treats it as a working prerequisite. Pack a 5mm wetsuit even in summer because thermoclines drop temperatures sharply at depth. Zone choice shapes the trip more than centre choice does. Marina Botafoch and Ibiza Town reach Don Pedro, Dado Pequeno, and La Plataforma. San Antonio reaches Ses Bledes and the western caves. Santa Eulalia covers the east, including La Catedral. Portinatx in the north is the small operator end; Subfari's no-fixed-time dives attract photographers and repeat divers who plan their year around shoulder-season trips.

Rocky coastline with numerous coves (calas), offshore islets (Es Vedra, Ses Bledes, Ses Margalides), underwater caves, tunnels, and extensive Posidonia oceanica meadows
