Castlereagh Sub Aqua Club

Castlereagh Sub Aqua Club (CSAC) was formed in 1975 and currently has a membership of approximately 65. These members come from all walks of life, with the common denominator being their desire to see and experience at first hand the fantastic treasures beneath Northern Ireland’s waves.

Book a Try Dive

If you have always wanted to learn to dive or are simply curious about scuba diving, then a Try Dive with Castlereagh Sub Aqua Club is the perfect introduction!

In the safe confines of the pool, a BSAC Instructor will introduce you to the basic skills and equipment needed to experience the thrill of breathing underwater for the very first time. Try Dives are free.

A typical Try Dive session lasts about 60 minutes. It involves poolside tuition on diving techniques and equipment, followed by a scuba dive in our pool with a BSAC-qualified instructor.

  • Run by experienced BSAC-qualified instructors
  • Help save time and money by trying scuba first
  • A great experience that could be the start of something amazing
  • All scuba equipment included
