Madeira is a year-round temperate-Atlantic dive destination off Portugal whose 376-hectare Garajau Partial Nature Reserve — Portugal's first exclusively marine reserve, no-take since 1986 — shelters diver-habituated dusky groupers, alongside an 85 m scuttled navy corvette, volcanic walls, and permit-only trips to the Desertas Islands, refuge of one of the Atlantic's last Mediterranean monk seal colonies.

Description
Madeira is a volcanic island in the subtropical North Atlantic, and its diving is temperate rather than tropical: boulder slopes, walls, and swim-throughs of dark lava rock dressed in sponges, anemones, and black coral instead of hard-coral reef. The flagship is the Garajau Partial Nature Reserve east of Funchal, created in 1986 and covering 376 hectares from the high-tide line to the 50 m depth contour, where all fishing is banned and dusky groupers of up to 60 kg have grown tame enough to follow divers. Wreck diving is strong: the 85 m corvette Afonso Cerqueira was scuttled south of Cabo Girão in 2018 as an artificial reef (12–33 m, penetrable for trained divers), and the Bowbelle — the Thames dredger of the 1989 Marchioness disaster — lies beyond 30 m off Ponta do Sol. The uninhabited Desertas Islands, about 23 km southeast, are a strict nature reserve holding roughly 20–40 Mediterranean monk seals; diving there runs only as full-day, weather-dependent trips with IFCN-authorised operators, and seal encounters are genuinely rare. Water runs 17–18°C in late winter and 23–25°C in late summer (5–7 mm exposure protection most of the year), visibility 30 m+ in the June–October prime season but 15–20 m in winter, when Atlantic swell can close shore entries. Porto Santo's celebrated wrecks (Madeirense, Pereira d'Eça) sit off a separate island reached by ferry or a short flight, not by Madeira day boats.
Highlights
What makes this dive worth the trip.
The Garajau Partial Nature Reserve, created in 1986 as Portugal's first exclusively marine protected area, covers 376 hectares from the high-tide line down to the 50 m depth contour east of Funchal; all fishing — commercial or sport — is prohibited throughout the reserve and vessel circulation is restricted.
Dusky groupers are the reserve's symbol: after nearly four decades of protection, individuals weighing up to 60 kg — a species that can live to around 50 years — are habituated to divers and approach and follow them through the dive, a behaviour rare anywhere else in Europe.
The 85 m Portuguese Navy corvette Afonso Cerqueira was intentionally scuttled south of Cabo Girão on 4 September 2018 as an artificial reef and immediately placed under protection; it sits upright in 12–33 m with the engine room, bridge, and cafeteria accessible to trained wreck divers.

Dive sites
7 signature sites at this destination.
Ponta do Garajau (Garajau Drift)
The most emblematic dive on Madeira, inside the no-take Garajau Partial Nature Reserve about 100 m offshore. High-piled volcanic boulders slope from roughly 15 m down to 30 m over sand, patrolled by the reserve's famous habituated dusky groupers, which approach divers closely. Usually run as a gentle one-way drift starting shallow, 8–10 minutes by boat from Caniço de Baixo; ranked among the best dive sites in Europe by several guides.

Corveta Afonso Cerqueira (F488)
An 85 m former Portuguese Navy corvette scuttled on 4 September 2018 south of Cabo Girão as an artificial reef and protected since sinking. The wreck sits upright and largely intact on sand at about 33 m with the superstructure from roughly 12–18 m; trained wreck divers can penetrate the engine room, bridge, and cafeteria through spacious passageways. Roughly 10 minutes by boat from the nearest harbour; the ecosystem is still developing but schools of fish, anemones, and groupers have moved in.

Bowbelle (Bom Rei)
The Thames aggregate dredger of the 1989 Marchioness disaster (51 deaths), sold to a Portuguese firm in 1996 and renamed Bom Rei. On 25 March 1996 her dredge pipe caught the seabed off Ponta do Sol, ruptured the hull, and she broke in two and sank with the loss of one crew member. The roughly 80 m wreck now rests at about 30 m (sections reported to 38 m) on Madeira's southwest coast and shelters large moray eels and groupers. Coordinates are the approximate position recorded for the sinking.

Caniço de Baixo House Reef (Easy Track)
The shore-entry house reef of the Caniço de Baixo dive bases on the sheltered southeast coast, at the edge of the Garajau reserve. Ladder and platform entries lead onto alternating volcanic rock and sand from 3 m to about 19 m, with garden eel colonies, trumpetfish, parrotfish, and resting stingrays; adjacent house-reef routes add a shallow cavern with dancing shrimps and black coral. The standard check-dive, training, and night-dive venue on the island.

Madeirense Wreck (Porto Santo)
A 70 m cargo vessel that once served Madeira's supply line, scuttled in October 2000 about a mile off Porto Santo island, now broken in two on sand at 24–35 m and densely overgrown after a quarter century — big groupers, schooling breams, and hydroid- and tunicate-covered superstructure. Porto Santo is a separate island reached by ferry (~2 h 15 min) or a short flight from Madeira with its own dive centres — it is not a Madeira day-boat trip. Coordinates are approximate.

Deserta Grande (West Coast)
Full-day, permit-only trips run by a handful of IFCN-authorised operators to the uninhabited Desertas Islands Nature Reserve about 23–25 km southeast of Madeira. Untouched volcanic walls and boulder fields drop past 40 m in exceptionally clear water, with pelagics passing through and — very rarely — a curious Mediterranean monk seal. Parts of the reserve are fully closed, diving is restricted to authorised zones, and crossings cancel in rough weather. Coordinates are approximate (leeward west coast of Deserta Grande).

T-Reef (Mamas)
Twin volcanic pinnacles inside the Garajau reserve rising from about 30 m to roughly 12 m below the surface — the 'Mamas' of the tourism board's seven traditional reserve spots. Fish-dense open-water structure with schooling barracuda, triggerfish, morays, and the occasional large stingray on the surrounding sand. Coordinates are approximate (mid-reserve, offshore of Caniço).
