The best hiking routes in County Kerry

County Kerry offers two distinct walking environments that appeal to different preferences. In Killarney National Park, the landscape is defined by ancient oak woodlands, low-altitude lakes, and manicured estate paths. Underfoot, you will mostly find firm gravel tracks, paved lanes, and occasional wooden boardwalks. This area is highly accessible, meaning the well-known spots near the lake shores can be busier with visitors, especially around the historic estate grounds. It is not a place for rugged, pathless navigation, but rather for structured walks through mature forests.

Outside of the national park, the wider Kerry landscape shifts to exposed sandstone ridges, open blanket bogs, and steep Atlantic cliffs. Here, the ground underfoot changes to rough peat, wet heather, and loose scree. The vegetation is shaped by grazing sheep and the constant maritime climate, leaving the hillsides bare of trees. Walking in these upland areas requires navigation skills, as formal signposts are rare once you leave the valley floors.

In May, the contrast between these two zones is most visible when the rhododendrons bloom in Killarney, while the high mountain passes like the Gap of Dunloe still carry the pale, dormant grasses of winter. Choosing where to walk depends on whether you prefer the sheltered, reliable paths of the oak woods or the demanding, open terrain of the rocky peninsulas.
