Ireland doesn't meet the Atlantic meekly but takes on the breakers, storms and everything else nature throws its way head on. The resulting coast is endlessly beguiling and ripe for exploration. One of the nation's top attractions, the Cliffs of Moher, have sheer rockfaces that plunge vertically to the ocean below. Across five miles of serrated edges, this never-ending pulse-pounding vista can be enjoyed from the top of cliffs or by tour boat from the roiling waters at their base. Elsewhere there's more seaside drama, including the jagged coast of the Ring of Kerry. Celtic tombs on deserted moors are the backdrop for crashing surf and tiny, resilient fishing villages.
