Tucked away where Killarney's three famous lakes converge, the Old Weir Bridge is a truly magical spot. To get there, you'll enjoy a lovely 30 minute walk from the nearest car park on the main road, following a path that meanders through ancient woodlands. You'll know you're close when you hear the rushing water. The charming, twin-arched stone bridge has stood for centuries and makes for a perfect photo, especially with the rapids flowing beneath it. It feels like a hidden gem, well worth the little bit of effort to reach. You can also take a refreshing dip in the waters here.
