The Azores
Nine volcanic islands in the mid-Atlantic, the Azores are Europe's serious big-animal destination. Summer expeditions run offshore to seamounts where Chilean devil rays circle in open blue water, while baited drifts near Faial bring in blue sharks. Conditions are oceanic — swell, current, real crossings — and the season is short, roughly June through October. Expect green calderas above the surface and volcanic rock, not coral, below it.
Perché immergersi qui
The Azores sit on the Mid-Atlantic Ridge, and the diving trades reef color for scale. The marquee trip is Princess Alice Bank, a seamount roughly 45 nautical miles from Faial and Pico whose summit rises to about 35 m; in high summer, squadrons of sicklefin devil rays carousel around divers hanging in blue water. Closer in, operators run blue-water drifts for blue sharks, and Santa Maria's Ambrosio plateau delivers its own mobula trains. Formigas and the Dollabarat reef, a remote marine reserve, add pinnacles swept by jacks and the occasional passing pelagic. Between dives this is sperm-whale country — the islands were a whaling center into the 1980s and are now one of the world's better whale-watching regions. None of it is guaranteed: crossings cancel in swell, animals follow food, and water stays cool even in August. Divers who accept those terms get Atlantic diving with almost no crowds and a genuine expedition feel inside Portuguese, EU-standard logistics.
Mese per mese
Most offshore operations run June–October; July–September is the reliable window for Princess Alice Bank and mobula aggregations, always weather-permitting. Many dive centers scale down or close in winter.

Vita marina su cui pianificare
Blue Shark
Bottlenose Dolphin
Mobula (Devil) Ray
Sperm Whale
Mola Mola (Ocean Sunfish)
Sicklefin devil rays (mobulas) at the seamounts in summer, blue sharks on baited drifts, occasional shortfin makos, big schools of jacks and yellowmouth barracuda, dusky groupers, loggerhead turtles drifting through, and whale-shark encounters some seasons off Santa Maria. Sperm whales and several dolphin species are seen from boats rather than on scuba.
Come arrivare e dove alloggiare
Come arrivare: Direct flights reach Ponta Delgada from Lisbon, Porto and several North American and European cities; inter-island hops or ferries connect Faial, Pico and Santa Maria. Most shark and seamount operators are based in Horta (Faial), Madalena (Pico) or Vila do Porto (Santa Maria).
Dove alloggiare: Horta and Madalena suit divers targeting the central-group banks; Santa Maria is the base for Ambrosio and summer pelagics; Ponta Delgada has the widest hotel choice but fewer offshore trips.
Costi: Editorial estimate for local two-tank boat dives; dedicated seamount expeditions (Princess Alice, Formigas) are full-day trips priced well above this.
Tra un'immersione e l'altra: Whale watching, the Capelinhos volcano museum on Faial, climbing Pico (Portugal's highest mountain), vineyard landscapes on Pico's UNESCO-listed lava fields, hot springs and crater lakes on Sao Miguel.
Sicurezza & aspetti pratici
Pericoli: Open-ocean exposure: long boat crossings, swell, surface current at the seamounts, and blue-water dives with no reference. Cancellations for weather are routine even in summer.
Seamount and shark dives are drift dives far from shore — carry a surface marker, dive within your training, and follow briefings on shark etiquette. Cool water argues for at least a 7 mm suit; many locals dive dry.
Camera iperbarica più vicina: Hyperbaric capability in the islands is limited and its status changes; confirm current arrangements with your operator. Emergencies go through 112 and DAN Europe.
