The Big Blue Diving is an established SSI centre located in Rethymno, Crete. For over 15 years, they have operated along the northern coast, providing access to a diverse range of underwater environments including vibrant reefs, historic wrecks, and complex cave systems.
The centre is built around a professional approach to diving, catering to those looking for a relaxed recreational experience as well as those pursuing advanced technical certifications. Their operations are centred on the MV Stella, which allows divers to reach more remote sites that are difficult to access from the shore.
The team is comprised of experienced SSI instructors who prioritise safety and personalised coaching. They maintain a strict ratio of no more than four divers per guide, ensuring that every person in the group receives adequate attention and thorough briefings before every descent.
Instruction is delivered with a focus on adapting to the individual's learning style. The centre is well-equipped to handle various levels of expertise, from those completing their first Open Water Diver course to technical divers working through complex sidemount or rebreather protocols.
The course catalogue at The Big Blue Diving is extensive, covering the full spectrum of SSI certifications. Beginners can start with the Open Water Diver course, with the option to progress through to Advanced levels.
For those looking to move beyond recreational limits, the centre offers specialised training in Rec Sidemount and Tec Sidemount. They also provide full Technical Diving Courses, including instruction for rebreather diving and Trimix, following the DIR approach to meet global technical standards.
The MV Stella serves as the primary platform for daily excursions. This vessel provides access to the more interesting sections of the north Cretan coast, reaching wrecks, reefs, and bays that remain sheltered from the shore-based crowds.
On board, the crew provides snacks to keep you fuelled between dives, and the team also offers underwater photography services to capture your excursions. The boat is configured to support both recreational outings and more demanding technical dives.
The centre provides a complete range of rental equipment for those not travelling with their own kit. This includes high-quality items from leading industry brands to ensure reliability and comfort during your dives.
