3 Best Sights in County Clare, Galway, and the Aran Islands, Ireland

The biggest and most famous of the Burren's megalithic tombs, Poulnabrone ("the hole of sorrows") is a portal grave/dolmen with a massive capstone and a majestic presence amid the craggy limestone fields shouldering the moody gray Burren skies. The monument was built around 4,500 years ago. Stand downwind and you might hear ancient whispers. There is a designated car park nearby with a historical timeline and a short gravel walkway to the dolmen (freely accessible). It's open and windy here, so grab an extra layer.

Wander off the beaten path to discover the inauguration site of Ireland’s greatest king, Brian Boru. Weaving through narrow country lanes, Magh Adhair appears to the left in the shape of a large grass-coated mound of earth, just past a small stone bridge that crosses Hell River. The mound is in fact a natural amphitheater where a lone voice could cut through large crowds during important regional ceremonies. It’s one of the most sacred druid sites in Munster and believed to be the final resting place of Adhar, whose brother, Aengus, built Dun Aengus—a giant hill fort overlooking the ocean in the Aran Islands. Watch out for the bullaun (basin) stone altar, which looks like a giant’s molar with a smooth, bowl-shape top. The druids believed that this altar captured hallowed water that protected their chieftains during and after life.

Park the car before reaching the site as the road is very narrow.

Built in 1584 to protect Spanish ships that were unloading cargoes of wines and brandies at the quays, this impressive stone arch is now the central feature of the newly restored Spanish Parade, a riverside piazza that draws a gathering of buskers and leisure seekers.
