The mouth of the Shannon – Ireland's longest river – is home to many species of animals. For example dolphins live and procreate here on a permanent basis. People also used to live in the middle of the Shannon Estuary on Scattery Island to be exact. Ferries run from Kilrush to the island. There are ruins of a monastery, a well preserved round tower, a garrison and an abandoned settlement to be found on the island.
There is also a ferry that crosses the Shannon Estuary and brings you on to the Wild Atlantic Wayalong the wonderful coast of North Kerry near Ballybunion – a popular holiday town with sheer cliffs and beautiful sandy beaches.
