The Islands of Ireland: Bullock Island gives up its secrets slowly

Several Irish islands are connected to the mainland by an isthmus as if the shore can’t bear to let them go — an umbilical cord that ties them to the shore till time erodes the link and renders it a ‘true’ island.
One such is Bullock Island at the mouth of Lough Hyne in West Cork, which is linked to the lough by the famous Rapids which permit seawater to enter the lough twice a day, thus rendering it one of Ireland’s three saltwater lakes.
