Killarney sits at the foot of Ireland's highest mountain range and beside three interconnected lakes, making it the finest hiking base in the country. Whether you have an hour or a week, there is a trail here that will stay with you.
Trail guide
Torc Waterfall & Mountain Loop
Easy–Moderate
Start at the Torc Waterfall car park, climb to the top of the falls, then continue up through open hillside to the Torc Mountain summit ridge. Panoramic views over all three lakes from the top. Return via the Old Kenmare Road through ancient oak woodland.
Muckross Lake Circuit
Easy
Flat, fully accessible loop around Muckross Lake through ancient yew and oak woodland. The best easy walk in the National Park. Often shared with cyclists and jaunting cars. Stunning views across the lake to the MacGillycuddy's Reeks throughout.
Gap of Dunloe
Moderate
A dramatic glacial valley walk between sheer mountain walls, passing five mountain lakes. Walk from Kate Kearney's Cottage to the Black Valley, then take a boat across the Upper Lake back to Killarney. One of the great Irish walking experiences.
Purple Mountain
Moderate
Less crowded than Carrauntoohil but offering equally spectacular views over the Gap of Dunloe and the three lakes. A rewarding summit with good paths most of the way. Best approached from Kate Kearney's Cottage.
Carrauntoohil — Devil's Ladder
Challenging
Ireland's highest mountain. The Devil's Ladder is the most popular route — a steep scree gully requiring hands and feet near the top. Excellent fitness and navigation skills required. Always check weather forecast. Guided ascents available from Killarney town.
Kerry Way — Killarney to Kenmare
Moderate
The first two stages of the 200km Kerry Way long-distance trail. Follows the Old Kenmare Road through the National Park to the Black Valley, then over mountain passes to Kenmare. Excellent accommodation at both ends. Luggage transfer services available.
Local tip
For Carrauntoohil, always hire a guide if it's your first time. Visibility can drop to zero within minutes on the summit. Several experienced local guiding companies operate from Killarney town — prices are typically €60–80 per person including equipment.
