It lies on the N69 coast road that runs along the estuary from Limerick before turning inland at Tarbert towards Listowel.

[2] Located on the N69 and N67 roads, Tarbert is connected by ferry (across the Shannon estuary) to Killimer in County Clare.

Also on the island is a small lighthouse and an electricity plant, Tarbert Power Station, with four oil-fired turbines and a capacity of 640MW.

Built in 1831, it was used for trying local court cases and for holding prisoners awaiting transfer to the County Jail in Tralee.

[7] Tarbert Island lighthouse, which is still operational, is a harbour light to guide vessels passing up and down the Shannon estuary.

It is built on a tidal rock on the north side of Tarbert Island and a cast iron bridge connects the lighthouse to the shore.
