This is a stunning cliff top walk on good, well-maintained gravel paths.  There are some uneven steps which could rate it moderate rather than easy.  However, on a clear day, the views of Rathlin Island, Scotland, Donegal and the Giant’s Causeway must make it one of the most spectacular walks in the world.  For a map, statistics and more photographs go to https://www.wikiloc.com/hiking-trails/dunseverick-to-giants-causeway-and-back-38682347
