On this exciting Kona submarine tour, dive deep below the cobalt waters just off the Kona coast, where an entire world of fish and marine creatures is waiting just below the surface. As the submarine descends towards the colorful reef, peer through the portholes at fish that swim to within inches of the submarine windows, and experience the sense of peace and calm in this world beneath the waves. This is a great way to explore underwater without even getting your hair wet, and, if you’re very lucky, there’s even the chance you could see a passing shark.
