Holy Island
Right next to Mountshannon is Iniscealtra, or Holy Island, one of the better-preserved examples of medieval monastic colonies which can be found all up along the River Shannon.
As one might expect from a monastic colony, Iniscealtra is a place of calm and solitude. One can either charter a boat for themselves and visit there (or just do a little fishing around the island itself) or opt for a full guided tour of the island which leave from Mountshannon Harbour during the tourist season.
