Important to know:
All dive centers at Nilaveli Beach are closed from approximately October to April (check their websites in advance).
At this time there is no season for scuba diving and it is only possible to go snorkeling at Pigeon Island (~8500 LKR/ person - boat there and back, equipment and ticket for the Pigeon Island National Park included).
Very good and professional organization. Had 2 brilliant fundives with Ashok and always felt save.
Very friendly team with even more friendly prices. Did a fun dive (already paid OW certified) and scuba diving introduction for my friend. We loved it.
Spent my first day in Nilaveli comparing the dive centers and after speaking to them chose AquaCreed to do my PADI Open Water Course.
AquaCreed had some great instructors that took me under their wing and helped me through the learning process. The experience can be somewhat daunting the first time you dive deep so I was happy that the instructor looked after me and kept making sure I was fine along the way.
The instructors were great to hang out with, you do spend 3 or 4 days so not insignificant ;-). I would really recommend AquaCreed when you are looking for professional service to do your PADI.
Superb service and training facilities. Excellent tutors, dive masters and equipment. Highly recommended.
