Currently working in Raja at a land based resort, having been to Bunaken and the Bangka Islands going back the last 20 years I always remember them as great places, and let's don't forget Komodo either, simply amazing. But to have Mantas literally jumping out of the water at you each day and sharks living underneath you it's hard to beat RA. One can only imagine that a large part of the 'Coral Triangle's' reef system was all like RA at one time.
