Connemara National Park is another of the absolute endless expanses of lake-land, coniferous forests, small but steep little bens and one of the only places in Ireland where you may possibly spot the red-spotted Irish deer!
A nearby must-visit POI is the Kylemore Abbey - built on the bank of a lake by an affluent British doctor, Mitchell Henry as a honeymoon gift to his wife, Margaret. It was later converted into a monastery by Benedictine nuns in 1920. The Abbey grounds house a restored Victorian Wall Garden, some really pristine woodland walks and a couple of high-terrain hikes. Great place for a day excursion
