Most people choose to skip the step of the Adventure Diver and just go straight on to their Advanced Open Water course. The certification you will receive after completing five Adventure dives, and two of the dives are required by PADI which are the Deep dive and the Navigation dive. Apart from these two you can choose from the ones mentioned in the Adventure diver section. You have the choice of doing this course as three separate daytrips with two dives a day to the Similan islands or as a 2 days 1 nights liveaboard.
