After a rocky and dreary section, the "view into paradise" comes through this bottleneck, almost out of nowhere. This walking section is unique!

A very impressive castle, part of which has collapsed into the sea along with the cliff. The visit can easily be combined with a visit to the Giant's Causeway.

"continual slur on Irish caving" It's actually only a few hundred metres is accessible and it's total length is thought to be 2km. No where near the longest cave in Ireland. Consider a trip in only if well equipped with a good light and helmet. Alternatively/also consider visiting McKenzies back lounge just down the road. A much drier watering hole. ;)

The beach is surrounded by dunes that are covered with wildflowers in summer, and it is an area of scientific interest with many fossils. It is a paradise for wildlife and one can spot rare butterflies, orchids, birds.
