Tenerife is the Canary Islands' easy-access volcanic diving hub: shore-entry lava reefs, the scuttled El Peñón tug at Tabaiba, and sandy bays where the Critically Endangered angelshark is sighted most reliably in the cooler November–April months, all in mild 19–24°C Atlantic water.

Description
The largest Canary Island wraps year-round, mostly shore-based diving around its sheltered eastern and southern coasts: Tabaiba and Radazul near Santa Cruz on the east side, and the Las Galletas / Costa del Silencio and Costa Adeje hubs in the south, with day boats running to walls and caves off Palm-Mar and Montaña Amarilla. The terrain is pure volcanism — lava tongues, tuff-cone reefs, arches and caverns — topped by the island's signature wreck, the 27 m harbour tug El Peñón, scuttled off Tabaiba in 2006 and now a walk-in artificial reef at 18–32 m. Tenerife's headline animal is the Critically Endangered angelshark (Squatina squatina): the Canaries are its last stronghold, and sandy bays like Abades, Tabaiba and Radazul produce regular sightings, far more frequently in the cooler-water months from late autumn to spring. The whole southwest coast lies inside the Teno-Rasca Special Area of Conservation, a 69,500 ha Natura 2000 site holding resident short-finned pilot whales and bottlenose dolphins (seen from boats, not on scuba) plus juvenile green and loggerhead turtles. Honest caveats: this is subtropical Atlantic, not coral-sea, diving — expect 19–20°C water in late winter, 10–30 m visibility, and reef life that is interesting rather than riotous; and El Puertito's famous 'turtle bay' colony was damaged by years of illegal feeding and harassment, so turtle encounters there are now occasional rather than guaranteed.
Highlights
What makes this dive worth the trip.
Tenerife is one of the best places on Earth to meet the Critically Endangered angelshark (Squatina squatina): sightings cluster at sandy-bottomed sites like Abades, Tabaiba, Radazul, Bocacangrejo, El Porís and Palm-Mar, where the flattened shark lies camouflaged in the sand — divers must keep their distance and never touch or disturb it.
Angelshark sightings in the Canaries are strongly seasonal: a six-year citizen-science series from a Canary Islands dive centre found divers met the species on roughly 1 in 3.6 dives (27.5%) in cool 18–21°C water, collapsing to about 2% of dives once the sea warms past 22°C — which makes the late-November-to-April window the realistic planning target.
The Canary Islands are the last global stronghold of the angelshark, protected since 2019 under the highest category of Spain's Endangered Species List ('in danger of extinction'); Tenerife's Las Teresitas beach was confirmed as the first known angelshark nursery area in the archipelago, and the Angel Shark Project publishes a diver code of conduct and collects sighting reports.

El Puertito (Armeñime)
A small semi-circular cove below Armeñime on the Costa Adeje, inside the Teno-Rasca SAC — calm, shallow and sandy with seagrass patches, diveable straight off the beach. Long famous for confiding green turtles, though the resident colony was damaged by years of illegal feeding and harassment, so treat a turtle as a bonus, not a promise; octopus, cuttlefish, wrasse and rays fill in the rest. Tourist boats anchor in the bay from mid-morning, so dive it early.

El Peñón Wreck (Tabaiba)
Tenerife's signature wreck: a 27 m harbour tug stripped clean and scuttled in 2006 a short swim off Tabaiba Baja, now resting at roughly 30 m with a 30-degree list to starboard, its top works starting around 18–20 m. The hull is colonized by polyps and anemones and patrolled by large moray eels, octopus, trumpetfish and passing barracuda, amberjack and the occasional butterfly ray on the surrounding sand — where angelsharks also turn up in the cool months. Depth makes nitrox popular; entry is a walk-in from the rocky shore.

Radazul
The island's busiest training and night-dive site: a very sheltered bay 10 km south of Santa Cruz with paved stairs and ramps into the water and multi-level profiles at 5, 12 and 18 m, while the volcanic wall outside the marina drops past 40 m within five minutes of shore. The basalt boulders and sand hold damselfish, trumpetfish, filefish, octopus, cuttlefish, cleaner shrimp and assorted rays; seahorses, turtles and even sunfish have been recorded. Deep wall sections are for appropriately certified divers, but the bay itself is genuinely beginner-friendly.

Montaña Amarilla
The underwater flank of a 71 m yellow tuff cone on the Costa del Silencio: a moon-like volcanic reef of spires, terraces, arches and small caves sloping from the shallows to about 25 m. Glasseyes and morays hide in the dark recesses, garden eels and flounders work the sand, and angelsharks appear on the sandy edges in the cooler months. Diveable from the rocky shore platform or as a short boat hop (about 2.5 km) from Las Galletas marina; conditions in the sheltered bay are usually gentle.

Abades
A broad, calm, sandy bay on the southeast coast with easy shore entries and depths from 2 m to about 25 m — and one of the most reliable angelshark areas in Tenerife. The shallow sand functions as habitat for juveniles ('baby angelsharks nestled in the sand' are regularly reported), with sightings concentrated from late autumn to early spring; stingrays, octopus, cuttlefish and lizardfish round out a relaxed dive. Low boat traffic and benign conditions make it a favourite for training and for patient sand-scanning.

Cueva del Palm Mar
A boat dive about ten minutes from Los Cristianos (or Las Galletas), beneath the cliffs of Montaña Guaza between Los Cristianos and Palm-Mar. A rock shelf at 18 m gives way to a wall, with the cave entrance at about 33 m marked by a memorial cross — inside sits a small Madonna statue, and stingrays often rest on the cave floor; the surrounding wall ('Palm Mar Wall' / El Bufadero, 7–30 m) carries morays, schooling fish and passing turtles. Maximum depth about 40 m: this one is for advanced divers.
