Today was a drive up to The Burren, a magnificent karst landscape stretching almost as far as you can see, crisscrossed with un-mortared stone walls that have stood for 1000 years.
In the center is Poulnabrone, a dolmen built in the Neolithic Era.
During a restorative excavation in 1985, the grave was found to contain 22 adults and 6 children.
I think this was the most memorable man-made thing I saw on the trip, with Loop Head being the best natural feature.
We also stopped at Ailwee Cave to see the underground waterfall.
