Holy Island or Iniscealtra lies, 2kms from the village. St. Caimin founded a monastic settlement here in the 7th century. The monks suffered repeatedly at the hands of the Vikings during the 9th and 10th centuries but the settlement was restored by the mighty King Brian Boru. Holy Island is a treasure trove of historical monuments including the remains of six churches, a well preserved round tower, bullaun stones, a holy well, four crosses and a graveyard which is still used for local burials. Boats depart daily from Mountshannon harbour from mid May to October. Crossings usually take about 15 minutes each way with an hour on the Island. If you wish to explore a bit further or maybe relax and have a picnic a later collection time can easily be arranged. Boats are also available for hire locally.
