On the south side of the peninsula are the sea cliffs of Sliabh Liag, the tallest in Europe. This dramatic landscape gave a glimpse at the sedimentary stone that makes up this landmass. There were terrific views through the clouds and rain of the Atlantic Ocean, the Sligo Mountains and Donegal Bay as we walked towards the top of the cliff face of Bunglas that rose over 600 yards above the raging ocean. The weather didn't cooperate with us this day. It was overcast and drizzling rain for most of the time. I had a better view at the observation area than all the way at the top.
