Glendalough

We'd visited Glendalough--a very old abbey ruin in the Wicklows--in 2009. We stopped by after Powerscourt and discovered we could over-night in the parking lot. Glendalough has half a dozen trails, some high, some low, and we spent the next morning hiking around the upper lake and visiting the abbey. The abbey itself goes back to nearly the earliest Christian times in Ireland, 6th-7th centuries, and the still-intact round tower is thought to have been constructed somewhere in the 9th-12th centuries. The setting is nearly Edenic.
