Which Diving Island Matches Your Experience?
Not every island suits every diver, and that is part of the fun. Before booking a flight, think about the kind of underwater experience you actually enjoy.
- Big marine life: If you’re dreaming of manta rays, mola mola, or thresher sharks, look no further than Nusa Penida and Malapascua.
- Shore-diving convenience: For those who prefer to explore at their own pace, Bonaire’s shore-accessible sites are hard to beat.
