Rose Bowl
The Bowl was inaugurated in 1991. The event is also held in the first quarter of each year with the 2012 event being won by Edmondstown Golf Club.

Participating clubs are: Milltown, Elm Park, Grange, Rathfarnham, Dun Laoghaire, Edmondstown and of course Castle. Hosting is rotated among the participating clubs.

Teams consist of eight players from each club. Castle's first victory in this event was in 2007, we are awaiting a second victory. Milltown hosted the event in 2012.
