I have used several dive companies in the Playa del Carmen area and this is the best one ever. Mike, Martin, Mario and the rest of the staff are extremely helpful, very knowledgeable, and patient. This was my 3rd year diving with Dive Aventuras as the other 2 companies I've tried had old, faulty equipment, made me haul all but the tanks myself, etc. Dive Aventuras has the boat a few minutes walk away and I didn't have to carry any of my equipment, a plus in hot weather. I dove with them for 3 days and each dive (6 in all) was different. Last year we did the Ceynotes with Mario and I can't begin to describe what an awesome experience it was. I wouldn't use anyone but Dive Aventuras and everyone I've recommended them to has come back with the same comment - best dive company ever.
