There is a vast array of everyday wonders around this island’s 7,800km rim. With the help of a group of coastal cognoscenti, here are 55 alternatives to the car-park charges at the Giant’s Causeway and the Cliffs of Moher and the clutter of signage along the not-so-wild Atlantic way. Always check weather forecasts and tides and local knowledge. And enjoy.

14 Geocaching, an outdoor treasure hunt using GPS-enabled devices developed by the Great Lighthouses of Ireland network at Hook Head Lighthouse.

In fact, they mark where mill stones were cut from the rock. greatlighthouses.com
15 Wexford's Lady's Lake/Our Lady's Lake, a coastal lagoon west of Carnsore Point reputedly occupied by a group of women in pre-Christian times.
