I have notice a lot of people complaining how diving in Asia is getting expensive. I completely disagree with this notion and still consider Asia as the best place for any diver to plan a trip. The past tragic events have made an impact on diving holidays in Asia especially Thailand but new destinations are made available to new divers looking for a life changing dive.
There are more competition to Asia in the last few years which is the rise of North African as a diving destination but facilities are still far from their Asian counterparts. But as a whole Asia especially Vietnam is coming out with hidden gems to finding great spots for diving.
Finding new destinations in Asia is not challenging. Joining a diving fair can get you all the best destinations in one location. You can get the best group or couple discounts not available online or in your travel agency.
