A couple weeks ago, on our Friday Irish Studies trip, we went on a 8km hike down the path of the only above-ground stream in the Burren. Because of the limestone pavement here, the rain goes through the porous rocks to create a series of underground streams and caves. But in this area, there's a layer of some other rock that the water has cut down to, and so flows overground to the sea. It was a lovely hike, and lots of fun. It was a really really really windy day, though - which in my opinion only made it more exciting!!
