I climbed Knocknarea which is a 1,000 foot limestone hill outside of Sligo. At the top there is this Cairn which has not been excavated but some suspect it may contain a neolilthic tomb. Apparently, this tourist can't read.
The views from the top of Knocknarea were amazing looking out to Sligo Bay and the Atlantic. Here you get a good sense of Irish green…40 shades according to Johnny Cash's famous song.
