Posidonia Ecosports

Located in Alicante, Posidonia Ecosports operates with a deep-rooted commitment to the Mediterranean ecosystem. Since its establishment in 2012, the centre has focused on 'buceo sostenible'—sustainable diving—ensuring that every excursion respects the delicate balance of the local seabed and its protected habitats.

The centre is uniquely positioned to offer more than just standard recreational dives. By integrating marine biology into their core operations, they provide a level of environmental insight that is rare in standard dive schools, making it a destination for those who want to understand the ocean as they explore it.

The team is composed entirely of marine biologists, providing a scientific backbone to every dive. The centre is led by Mercedes Varela, a Doctor of Marine Biology with over 25 years of experience in research and marine popularisation, having worked in environments ranging from the Antarctic to Africa.

Instruction is provided in several languages, including Spanish, English, French, German, Italian, and Dutch. This multilingual approach makes the centre highly accessible to international divers looking for professional training or guided explorations.

As an SDI affiliated centre, they offer a structured path from beginner certifications to professional instructor training. Their pedagogical approach is heavily influenced by ecology, ensuring that students learn proper buoyancy and environmental stewardship alongside their technical skills.

The course catalogue is extensive, covering the full spectrum of SDI certifications. Beginners can start with Scuba Diver or Open Water Diver (OWD) courses, with various packages available to suit different training needs.

For those looking to advance, the centre offers training through to Divemaster and Instructor levels. They also specialise in niche educational programmes, such as Scientific Diving (Buceo Científico), which is validated by the College of Biologists of the Valencian Community, and various technical diving courses.

The centre provides full equipment hire for divers who prefer not to carry their own kit. This includes everything required for a standard dive, from regulators to BCDs and fins.

For those staying in the local area through their weekend packages, the centre coordinates logistics between the hotel in Rincón de Loix and the dive school, ensuring a seamless transition from accommodation to the water.

The marine life around Alicante is defined by the healthy Posidonia oceanica seagrass meadows. These habitats support large schools of fish, including dentex, sea bream, and various species of salpa and bogue. You will often encounter larger pelagics such as barracuda, seriola, and various groupers patrolling the rocky structures.

Macro life is abundant for those who observe closely. The seabed is home to octopus, moray eels, and various sea urchins, alongside smaller treasures like seahorses (Hippocampus guttulatus). You can also find diverse invertebrates and sea squirts tucked into the crevices of the reef.

In the open water, sightings of common dolphins and bottlenose dolphins are possible. During migration periods, you may also have the opportunity to see sperm whales and rorquals passing through the region.

Diving in this region is primarily conducted via boat excursions. The variety of sites, from shallow seagrass meadows to deeper underwater mountains, allows for a range of diving experiences depending on the swell and local conditions.
