I found that Andaman, particularly in the Barefoot resort, and otherwise there are lots of certified freelancers who will give you a scuba diving lesson, that you get the best as well as the least expensive packages for scuba diving. And from what feeling travelers told me, the Globetrotting hippies who can be trusted particularly for knowing the least expensive experiences, adventure sports to accommodation, Andaman offers the lowest rates for diving. So low that people are beginning to come to Andaman just for the scuba diving rather than do a costly one on Thailand for example. Also, especially in Barefoot (that has two results on Havelock, if you're looking for really inexpensive but wonderful place to stay, you can book a hut facing the ocean in the resort that cost me a hundred and fifty some six years ago along with a scuba diving stint at two thousand. just book in advance.. also check Barefoot, for I believe it was in controversy some months ago.
