Kilrush Marina lies within a harbour located on the North side of the Shannon Estuary. It offers a number of trips and services for maritime enthusiasts wanting to explore the uncrowded Western Ireland waters.

Within the harbour is the marina centre itself and a well-equipped boatyard that offers boat repairs, service facilities, a slip way and a fuelling berth. There are also a number of excursions available including yacht charters, deep-sea angling, sail training and day trips. The marina is particularly popular with visitors wanting to take day trips to Scattery Island and for Dolphin Watch cruises.
