The concept of Insider Divers is that our group trips are guided by experts, we call them the INSIDERS, that are knowledgable in the different areas of the marine environment. These group leaders take over all organizational aspects of your tour and enrich your experience with their knowledge and insight. You can relax knowing that you will get the best possible adventure and learn about the amazing animals that we seek out. Never stop learning!
