Building Confident Divers: Personalized Training with Dive Isla Bella


At Dive Isla Bella, the focus is on developing strong diving skills, confidence, and safe habits rather than depending on advanced equipment. Offering training through major diving organizations including PADI, NAUI, and SSI, the courses provide flexibility for students to choose the learning system that best fits their preferences. Referrals from universal agency systems are also welcomed, and required course materials are delivered directly to students for a convenient learning experience.


The open water certification course combines pool training sessions, boat dives, classroom lessons, and knowledge assessments to create a complete diving education. Students can choose an intensive schedule completed over several days or spread the training across multiple half-day sessions during their vacation. With small class sizes and a nearly private learning environment, instructors can adapt the pace and approach to each student’s individual needs


Dive Isla Bella incorporates the essential skills and safety principles shared across major certification agencies while respecting the unique strengths of each system. NAUI provides a detailed academic approach with traditional study materials, including books, workbooks, tables, and logbooks, making it ideal for students who want a deeper understanding of diving theory. SSI offers a modern digital learning platform that allows students to begin coursework immediately and access materials across multiple devices. PADI provides flexible online and traditional learning options with structured lessons designed to be accessible for a wide range of ages and experience levels.


Every course is designed to create capable, responsible, and confident divers prepared to explore the underwater world safely. Health and safety guidelines are carefully followed throughout all training activities, and students must allow at least eighteen hours between their final dive and any flights home. Available for participants aged ten and above, the certification experience provides the knowledge, practical skills, and confidence needed for a lifetime of underwater adventures.

I had an absolutely fantastic weekend doing my orientation dive (and fun dives) with Ocean Divers at Killary Fjord! From the moment I arrived every member of staff and all the other divers were incredibly welcoming, friendly and helpful. The atmosphere was supportive and relaxed, making it easy to feel comfortable even if you’re just starting out like me (10 dives previously). There were a lot of divers, but each in small groups with their own dive master or dive instructor and grouped together in the OW/AOW courses or fun dives. While I had already done my OW elsewhere, I’ll definitely be doing the advanced course and further dives with these guys as the level of dedication and commitment that goes into making their students be successful divers is visible. Bring a bit of patience for the initial response period if you reach out during a very busy time - it‘s hard to respond when you’re always in the water 😄 but I honestly can’t recommend them enough if you’re looking to become a good diver and explore Irelands underwater world with a genuinely lovely group of people.

I’m doing the drysuit diver course with Oceandivers at the moment. I was having trouble getting my buoyancy right, so had six pool sessions to get it right at no extra charge!! What a crew Oceandivers have. There was no pressure, just take your time and get it right. Dan is always on hand to help you out and the rest of the lads are so helpful. I had my first sea dive for the buoyancy certification today off Dalkey island. It was fantastic!! The extra lessons really paid off. I cannot recommend the Oceandivers crew highly enough. It is and has been a pleasure working with Oceandivers to get my drysuit certification. Can’t wait to get back in the water with the crew!!

I got my OW course with Oceandivers in the previous two months and they are really professional and helpful. Especially, I would like to thank my instructor Alan, he is really amazing experience diver and nice advisor. Great enjoy my training with him and also thank other instructors, divemasters and staffs from Oceandivers.
