This is the spot where my daughters have their first taste of scuba diving. The site was not that great but it was good enough for discover scuba, at least. The site was about 20 minutes by boat from marina RC.
Discover Scuba is a first step for those who want to experience how it feels under water. If you do really like it, then you need to enroll for Open Water Scuba Diving Course. Upon successful completion of this course, you will become a licensed diver which will lead you to a new world under.
