Scuba Diving in the Canary Islands: Choosing Your Island

Scuba diving in the Canary Islands solves the European diver's oldest problem: what to do between October and May. Eight volcanic islands off the African coast sit in Atlantic water that never leaves the 18-24°C band, four hours from most of Europe, with lava seabeds that make every dive an architecture tour — arches, caverns, swim-throughs and walls, most of them reachable from shore.

The islands differ more than first-time visitors expect, and choosing the right one is most of planning the trip. Here is the archipelago, island by island — all of them mapped in our Spain dive-site catalogue.

Lanzarote: the all-rounder

The busiest dive island and the easiest recommendation. Puerto del Carmen's Playa Chica packs caverns, walls and the famous Cathedral cave into one shore-entry bay; Playa Blanca has the Museo Atlántico, Europe's first underwater sculpture museum; and the island's sandy bays are the archipelago's most reliable place to meet a wintering angel shark. Our Lanzarote guide covers it in full.

Tenerife: turtles, rays and volume

The biggest island carries the biggest dive industry, based along the south coast around Los Cristianos, Las Galletas and Costa Adeje. The diving is volcanic reef and sand at friendly depths, with the archipelago's most dependable green turtles and big rays — stingrays, butterfly rays and eagle rays — as the draws. Offshore, resident pilot whales patrol the deep channel towards La Gomera, the subject of a whole whale-watching industry. Tenerife suits divers sharing a holiday with non-divers: the resort infrastructure is enormous.

Gran Canaria: El Cabrón and the wrecks

Gran Canaria's east coast holds El Cabrón marine reserve at Arinaga — arches and caverns with the density of fish only protection produces, and a strong angel shark record of its own. The south around Mogán adds a cluster of scuttled wrecks on sand. Conditions are a touch more exposed than Lanzarote's leeward bays; the reward is fishier reefs.

Fuerteventura: clear water and Lobos

The channel between Corralejo and the islet of Lobos — a protected marine reserve — gives Fuerteventura the clearest water in the eastern islands, over white sand that turns the light Caribbean-blue. The diving is relaxed: reef fingers, rays on sand, barracuda in the current seams. It pairs naturally with the island's surf-and-beach holiday scene.

La Palma and El Hierro: the wild west

The young western islands are the connoisseur's Canaries. La Palma is lava architecture at its most dramatic — towers, tunnels and the Malpique dive, where 40 stone crosses stand on the seabed as a memorial. El Hierro, the smallest and remotest island, has the archipelago's best diving outright: the La Restinga reserve on the Mar de las Calmas, where visibility stretches past 30 metres and groupers have grown old unhunted. Neither island does mass tourism; both reward divers who travel for the diving itself.

La Gomera and tiny La Graciosa complete the eight, both quiet, both worth a day if you are there.

Which island, in one table

Seasons

There is no season to avoid. Winter (18-19°C, 7mm suits) is angel shark time and the islands' busiest diving months, because the rest of Europe is cold. Summer and early autumn (up to 24°C) bring the warmest water and calmest seas. Courses run every month — worth knowing if a winter certification is the plan — and the 18-hour no-fly rule is the only scheduling constraint that never changes.
