Cliffs of Moher

Eight kilometres of sheer Namurian shale and sandstone plunging 214 metres into the Atlantic; the O'Brien's Tower marks the highest vantage point; walk the coastal path at 7 pm during the summer solstice; the horizontal light ignites the cliff face into a saturated gold while thousands of nesting puffins create a chaotic; rhythmic white noise against the roar of the swell.

Slieve League

Among the highest sea cliffs in Europe; plunging 601 metres directly into the churning Atlantic; the 'One Man Path' traverses a narrow; jagged ridge of quartzite and schist; stand at Bunglas Point during a gale; the ocean spray is carried upward by the thermals to meet the low-hanging clouds while the sheer scale makes the fishing boats below appear like static white specks.
