Warm, clear water all year round, dramatic volcanic seascapes and marine life you won't see elsewhere in Europe — the Canary Islands are one of the continent's finest diving destinations. Because the islands are volcanic and drop steeply into the Atlantic, you get lava arches, caves, walls and reefs teeming with fish just minutes from shore, in water that rarely turns cold. Whether you're taking your very first breaths underwater on a "try dive" or you're a seasoned diver chasing angel sharks and underwater sculptures, there's a site here for you.
Why dive the Canaries?
The appeal starts with the conditions. Sea temperatures are mild all year — cooler in late winter, warmest in autumn — so with the right wetsuit you can dive comfortably in any month. Visibility is often excellent, the volcanic terrain creates spectacular underwater scenery, and the mix of Atlantic and subtropical species means unusual encounters. Add a well-developed network of dive centres used to English-speaking visitors, and it's a brilliant place to learn, qualify or simply log some memorable dives.
Great for beginners. Many resorts offer a supervised "try dive" or discover-scuba session in a pool or sheltered bay — no qualification needed and a superb taster. If you're bitten by the bug, the islands are also an affordable, sunny place to earn your first Open Water certification over a few days.
Top diving spots by island
El Hierro — Mar de las Calmas
The tiny, far-western island of El Hierro is a diver's dream. Its Mar de las Calmas marine reserve, off the village of La Restinga, offers some of the clearest water and richest marine life in the whole archipelago — dramatic drop-offs, big shoals, groupers and the sense of a genuinely wild, protected sea. Serious divers rate it among the best in Europe, and its remoteness keeps it wonderfully uncrowded.
Lanzarote — Museo Atlántico & Puerto del Carmen
Lanzarote pairs classic diving with something unique: the Museo Atlántico, Europe's first underwater sculpture museum, where eerie human figures by artist Jason deCaires Taylor sit on the seabed off the south coast, doubling as an artificial reef. Elsewhere, the strip off Puerto del Carmen is a long-established, easy-access shore-diving playground with reefs, wrecks and a famous drop-off — ideal for all levels. See more of the island's attractions on our Lanzarote guide.
Gran Canaria — El Cabrón
On the east coast of Gran Canaria, the El Cabrón marine reserve near Arinaga is the island's standout site — a maze of arches, caves, canyons and walls alive with fish, best reached as a shore dive with a local guide. The south's resort waters also offer gentler dives and wrecks suitable for newcomers, so Gran Canaria works whatever your level.
Tenerife
The biggest island has plenty of choice, particularly along the south and south-west coasts around Las Galletas, Los Cristianos and the cliffs of Los Gigantes. Volcanic reefs, caves and the chance of rays and turtles make it a reliable, well-serviced base for diving on Tenerife.
What you'll see
The Canaries' marine life is a real draw. Highlights include the angel shark — a rare, harmless flat-bodied shark that shelters in these waters in winter, making the islands one of the world's best places to see them — along with rays and stingrays, moray eels, barracuda, cuttlefish, octopus and, if you're lucky, sea turtles. Big shoals of colourful fish drift over the reefs, and the volcanic caves and arches add drama to every dive.
Dive safely and respect the reserves. Always dive with a reputable, insured centre, check that instructors are properly certified, and never touch or chase the wildlife — many sites are protected marine reserves. Watch out for the odd hazard such as sea urchins, and remember the golden rule: leave at least 24 hours between your last dive and flying home.
Courses, centres and costs
Dive centres across the resorts cater to everyone, from complete beginners to technical divers, and most run internationally recognised PADI or SSI courses. You'll find try-dives, full certification courses, guided shore and boat dives, and equipment hire. Prices vary with the operator and season, so compare a few and read recent reviews; a multi-dive package is usually better value than paying dive by dive. English is widely spoken at resort dive shops.
Beyond scuba
You don't have to strap on a tank to enjoy the underwater world. Snorkelling over the volcanic reefs is superb and free, and there's a huge range of boat trips and watersports if you'd rather stay near the surface — from glass-bottom boats to snorkel safaris. For getting from island to island to reach the best dive sites, the inter-island ferries make trips like a diving pilgrimage to El Hierro entirely doable.
Volcanic arches, an underwater museum and the elusive angel shark — the Canaries offer year-round diving with a character all of its own.
From your first bubbles in a sheltered bay to a bucket-list dive in El Hierro's crystal reserve, the islands reward divers of every level. Fit it into a wider itinerary of things to do and you'll come home with the best souvenirs of all — the ones you can't buy.
