Welcome to Trident Sub Aqua Club's website. Our club was founded in 1975 and currently has 25 members. We are members of the Irish Underwater Council (Comhairle Fo Thuinn) which is affiliated to C.M.A.S (Confederiation Mondiale des Activities Subaquatiques).

Between March and October we dive twice weekly off Dalkey Island and the Muglins . Our clubhouse is situated at Bulloch Harbour, Dalkey. We also organize dive weekends away each month and an annual dive holiday abroad.

Regular Sunday snorkels at Greystones would blow anybody's cobwebs away! But for the less hearty our winter pool sessions and dive lectures act as a opportunity to train new recruits and also to keep current members up to scratch. If you have ever considered following in the footsteps of Jacques Cousteau, this is your chance.
