We organize dive weekends away from Dublin each summer month and, over the years, have dived many parts of the Irish coastline including Hook, Baltimore, Ballinskelligs, Valentia, Dingle, Castlegregory, Kilkee, the Aran Islands, Killary, Inish Bofin, Inish Turk, Clear Island, Mullaghmore, St. John Point, Tory Island, Carrigart, Rathlin Island and Strangford Lough.

Each year we endeavour to find new, exciting destinations for our annual club holiday. In recent years we have made trips to Bonaire (Dutch Antilles) in the Caribean, Sharm El Sheikh, Marsa Alam (Egypt) and Aqaba (Jordan) on the Red Sea, Estartit, Gozo, La Manga, Sicily and the Aeolian Islands in the Mediterranean, Turkey in the Adriatic, Santa Catalina Island off California and the Sea of Cortez in Western Mexico.

Trident Sub-Aqua Club actively encourages new members to join and the club devotes much voluntary time into training new recruits with practical lessons in a swimming pool, lectures and trainee dives in Dublin Bay and throughout the country.

Our compressor is located in our clubhouse, which is situated on the pier at Bulloch Harbour in Dalkey. Between March and November, we dive regularly in Dublin Bay particularly around Dalkey Island and The Muglins.

A 7.2m RIB (rigid hull inflatable boat) was purchased in 2008; it is berthed in Dun Laoghaire Marina.
