As the global population increases and world travel becomes more accessible for many people, it is increasingly difficult to find dive sites that offer spectacular marine life and minimal tourism. Many areas of world class diving are overrun in peak season with boats and large dive groups, which is a far cry from the serenity and peace of scuba diving that most of us seek. There are however some lesser-known diving locations to explore, if you are prepared to go off the beaten track and begin a travel adventure both topside and underwater.
