Cursos Disponibles
8 cursosOpen Water Diver
The SSI Open Water Diver at Arrecifal is structured to keep the theory off the island. After booking, SSI sends a personal link to your digital manual — you work through it at home, at your pace, before travelling to La Restinga. By the time you arrive, the academic side is done, and your three days on El Hierro go entirely to in-water training. That's not just a convenience; on an island where accommodation and boat spaces fill fast in season, it makes the most of every day. The course runs across three days minimum, though Arrecifal recommends building in an extra day for confidence and exploration. The confined-water sessions — where skills like mask clearing, regulator recovery, and buoyancy control are first practised — use a controlled setting before moving to open water. The four open-water training dives then apply those same skills in the real environment: the volcanic seabed of the Mar de Las Calmas, with its lava formations, garden eels, morays, and resident groupers. The certification is SSI Open Water Diver, recognised internationally and ISO-certified. It qualifies you to dive with a buddy of equal or higher certification in conditions equivalent to your training, to a maximum of 18 metres. That 18-metre limit opens up the majority of recreational dive sites worldwide, including most of what El Hierro itself offers. If you subsequently want to go deeper, the Advanced Adventurer course and Deep specialty both pick up from where this one leaves off. Minimum age is 10 years, which means families can certify together. The same medical questionnaire required for the Bautismo applies here. The online theory component — including the digital manual — is included in the course price, so there's nothing extra to purchase before arriving.
BAUTISMO
The Bautismo at Arrecifal is the entry point to diving in El Hierro — a three-hour session that covers a brief theory and practical introduction on land before heading out by boat into the Mar de Las Calmas. The crossing takes around 20 minutes, which already gives you a feel for the reserve and the volcanic coastline of La Restinga. The dive itself takes place outside the Marine Reserve proper, but still over the same volcanic seabed that defines El Hierro's underwater character. You stay with an instructor throughout — not alongside a group, but directly with your guide. That hands-on approach is particularly important for first-timers who haven't yet developed any feel for buoyancy or breathing rhythm underwater. The instructors at Arrecifal are multilingual certified professionals, not just dive leaders, which means any questions you have — about what you're seeing, how to equalise, how to signal — get real answers. The minimum age is 10 years, which makes the Bautismo a realistic option for family visits to El Hierro. A completed medical questionnaire is required before the dive; if there are any flagged conditions, a medical fitness certificate may be needed. Beyond that, there are no prerequisites — the course is designed to be accessible to anyone in reasonable health who wants their first experience underwater. The Mar de Las Calmas has conditions that work in favour of first-timers: calm water, good visibility, and relatively mild currents compared to more exposed dive sites. Breathing compressed air for the first time, feeling neutral buoyancy, watching the volcanic rock and marine life from a metre away — the experience is hard to replicate anywhere, and El Hierro's seabed makes it a particularly memorable introduction.
ADVANCED
The SSI Advanced Adventurer at Arrecifal runs across two days and five dives. Three of those dives are fixed: Perfect Buoyancy, Navigation, and Deep Diving. The remaining two are chosen from a list that includes Night and Limited Visibility, Boat Diving, Waves Tides and Currents, and Search and Recovery. The structure lets you sample disciplines before committing to a full specialty course — useful if you're not sure whether night diving or wreck navigation is the direction you want to take next. The deep dive component takes the course to 30 metres, extending your certified range beyond the 18-metre Open Water limit. On El Hierro, that depth opens access to the more dramatic sections of the volcanic walls — areas where the rock drops sharply and the density of life changes as you descend. Buoyancy at depth behaves differently than in shallow water, and the deep dive session specifically addresses that adjustment under instructor supervision. The buoyancy dive, often described by SSI instructors as among the most technically valuable of the advanced dives, addresses the precision control that separates comfortable divers from skilled ones. Doing it in the clear water of the Mar de Las Calmas — visibility regularly above 40 metres — gives visual feedback that's hard to match in murkier environments. Navigation follows a similar logic: clean water and readable seabed features make compass work and natural navigation much more teachable than in low-vis conditions. Minimum age is 10 years. Prerequisites are Open Water Diver or equivalent from a recognised agency — non-SSI certifications are accepted at this level. The course can be combined with the Nitrox or Deep specialty for divers who want to maximise their time on El Hierro and leave with multiple endorsements.
NITROX
The Nitrox specialty at Arrecifal can be completed in a single day, and it's one of the few courses that doesn't require open-water dives — the core content is academic and pre-dive planning, with the optional dive component available for those who want it. The practical payoff is real: Nitrox mixes of up to 40% oxygen extend no-decompression limits compared to air, reduce surface intervals between dives, and increase the safety margin on repetitive dive days. For divers on a multi-day schedule at El Hierro — doing two dives a day across three or four days — the arithmetic adds up quickly. Longer no-deco limits mean more bottom time on each dive. Shorter surface intervals mean the second dive of the day can start sooner. Arrecifal runs two dives per morning, so having Nitrox certification lets you get more out of each session, especially on deeper sites where air-based limits compress fast. The course teaches planning and safe use of enriched air mixes up to 40% oxygen: how to analyse the mix, set your dive computer, calculate maximum operating depth, and understand the physiological differences from standard air. These are tools you then carry to every dive you do — not just on El Hierro, but anywhere in the world where Nitrox is offered. Prerequisite is Open Water Diver or equivalent from a recognised agency. Minimum age is 10 years. Given the planning-heavy nature of the course, it pairs well with any multi-day diving programme at Arrecifal, and the centre can incorporate it alongside guided dives rather than consuming a separate day entirely.
Buceo PROFUNDO
The SSI Deep Diving specialty at Arrecifal runs two days and includes three open-water dives, taking students to the 40-metre limit of recreational diving. El Hierro's continental shelf drops steeply and fast — depth is genuinely accessible here, which makes the island a practical environment for this kind of training. The volcanic walls that start near the surface continue downward, and the deeper sections have their own character: different light, different species mix, and compressed no-decompression time that demands careful planning. The course covers planning and executing dives between 18 and 40 metres safely. That includes understanding narcosis, monitoring no-decompression limits at depth, managing gas consumption when the bottom clock is running, and the discipline of ascent rates and safety stops. These aren't abstract concerns on El Hierro — El Bajón, one of the signature sites, drops well below recreational limits, and understanding where the edges are matters when you're in the water. The three training dives are conducted under direct instructor supervision, progressively working toward the 40-metre depth limit. Each dive is preceded by a full briefing specific to what will be practised — not a generic site briefing, but a structured session oriented to the course objectives. Arrecifal's instructors are experienced in this depth range on the local sites, which means the briefings are grounded in real knowledge of how conditions change as you go deeper here. Minimum age for this specialty is 15 years — older than the standard 10-year floor for most of Arrecifal's course catalogue. Prerequisite is Open Water Diver or equivalent from a recognised training agency. The Deep specialty is a prerequisite for some of SSI's more advanced programmes, so completing it at Arrecifal opens the path to further training if that's the direction you're heading.
REACT RIGHT
React Right is SSI's first aid and emergency response course, running across a single day. The programme combines academic sessions with practical training scenarios and certifies the holder to act as a first responder in medical emergencies — administering first aid, CPR, and oxygen — for a period of two years from the date of certification. After two years, a renewal is required to keep the certification active. At Arrecifal, React Right is most commonly completed by divers enrolling in the Stress and Rescue specialty, where current first aid and CPR certification is a hard prerequisite. The two courses can run back-to-back — React Right on day one, then four days of Stress and Rescue — making for an efficient five-day block without gaps in training continuity. Arrecifal can structure the combined programme if that's the approach you want to take. The minimum age is 12 years and there are no diving prerequisites — React Right is a standalone first aid qualification that happens to be delivered by a dive centre. That said, the practical scenarios are designed with the diving context in mind: the emergencies covered reflect the kinds of situations that arise on and around boats, at dive sites, and in the water. For divers who hold an expired first aid certification and need to renew before taking Stress and Rescue or Divemaster, React Right is the SSI pathway. The certification is issued through SSI's digital system, consistent with all their other qualifications.
DIVEMASTER
The SSI Divemaster programme at Arrecifal runs 20 days — the longest and most demanding offering on their course calendar. The qualification recognises candidates with the knowledge and training to work as a certified dive professional: assisting SSI instructors with beginner and continuing education programmes, planning and guiding dives, and taking on the responsibilities that come with being the most experienced person in the water for a group of recreational divers. Prerequisites are specific and non-negotiable at this level. Candidates must hold both SSI Diver Stress and Rescue and SSI Science of Diving, and must have SSI Professional Dive Guide in active status — non-SSI equivalents are not accepted for these prerequisites, unlike at recreational course levels. The 60-dive minimum with at least 40 hours of bottom time ensures candidates have real experience before the training begins. At Arrecifal, the guided dive programme and specialty courses provide a natural path toward building that log. Twenty days at Arrecifal means twenty days diving El Hierro as a student diver turning professional. The variety of sites in the Mar de Las Calmas — volcanic walls, pinnacles, sandy channels, caves, the post-eruption structure of El Bajón — provides a range of environments and conditions to train across. Guiding in a marine reserve with permanent moorings and site-specific protocols is a more demanding context than guiding on open, unregulated sites, which benefits the quality of the training. For candidates considering a Divemaster at El Hierro, the practical aspect of working in a UNESCO Biosphere Reserve with active conservation protocols and a marine biologist on the Arrecifal team is a meaningful professional context. Minimum age is 18 years.
Stress & Rescue
The SSI Diver Stress and Rescue course at Arrecifal runs four days and is consistently described by SSI instructors as the most demanding course in the recreational programme — technically, physically, and mentally. The course covers self-rescue, recognising and managing stress in other divers, emergency equipment handling, rescuing a panicked diver, and managing an unconscious diver in the water. None of this is theoretical comfort: it's practised repeatedly in scenarios until the responses become instinctive. The four-day duration reflects how much ground the course covers and how much repetition is built into the training. Stress and rescue skills degrade without practice, and the course is designed to install habits under pressure rather than knowledge for an exam. Arrecifal's instructors are the same multilingual certified professionals who guide recreational dives — they know the local conditions and can run scenarios that are grounded in what actually happens on El Hierro's dive sites. A prerequisite for certification is current first aid and CPR training, no older than two years at the point of card issuance. If you don't hold that certification, Arrecifal offers the React Right course (one day) which can be completed back-to-back with the Stress and Rescue programme. The two together run five days total and leave you with both certifications. Minimum age is 12 years. The Stress and Rescue certification is a prerequisite for the Divemaster programme, so divers heading toward a professional qualification will need it in any case. For recreational divers with no professional aspirations, the course changes how you dive — the awareness of your buddy, of group dynamics, of early signs of problems — in ways that make every dive after it more considered.

Las dudas más habituales de quienes están a punto de reservar
No. The Bautismo (intro dive) is open to anyone from age 10 with no prior experience. It runs from the boat, includes about 20 minutes crossing the Mar de Las Calmas, and is fully supervised by an instructor throughout. Certified divers need a valid certification card, a completed medical questionnaire, and dive insurance — Arrecifal can arrange the insurance for you.
The Mar de Las Calmas Marine Reserve enforces a cap of 10 divers plus guides per site at any one time. Arrecifal keeps to this limit. All dives are guided by multilingual certified instructors — you are not dropped at the site and left to explore alone.
The centre operates in Spanish, English, French, and German. Reviews from guests confirm instruction and guiding in all four languages. The website is fully available in Spanish, English, French, and German.
Water temperature ranges from 17°C in winter to 24°C in summer. A 5mm suit covers the warmer months; a 7mm is recommended in winter. Arrecifal has both thicknesses in their rental fleet, along with thermal undersuits and hoods for the colder periods. Full rental equipment is available — wetsuits, BCDs, regulators, computers, tanks — all maintained to current standards.
Yes, and that's the point. After booking any SSI course, Arrecifal sends a personal link through SSI to your digital manual. You complete the theory at home, at your own pace, before travelling. Once in La Restinga, all your time goes to in-water sessions. The online theory access is included in the course price — nothing extra to buy.
Yes. La Restinga has one hotel; almost everything else is apartments, and the centre can guide you to options and make the reservation. For car rental they work with a local company — cars can be picked up at Valverde Airport or at the La Estaca ferry terminal. Accommodation fills fast in high season and on long weekends, so they recommend booking well in advance.
The Mar de Las Calmas reserve sits at the edge of a steeply dropping continental shelf, which draws oceanic species close to shore. Devil rays, hammerhead sharks, sea turtles, sunfish, dolphins, and occasional whales have all been documented in the area. None are guaranteed on any given dive, but the site's conservation status and low fishing pressure mean the encounters are genuine rather than managed.
Arrecifal operates year-round. The reserve is sheltered from the dominant trade winds, which keeps conditions diveable across all months. Visibility exceeds 40 metres for most of the year and is rarely below 20 metres. Water temperature is lowest in late winter (around 17°C) and peaks in late summer (around 24°C). Summer brings warmer water and longer days; winter brings slightly richer pelagic activity.
