Overview
The Gap of Dunloe (Irish: Bearna an Choimín) is one of Ireland’s most dramatic natural corridors. Carved between the towering MacGillycuddy’s Reeks to the west and the Purple Mountain group to the east, this narrow, 11-kilometre valley channels the River Loe through a chain of five glacial lakes. It’s a landscape that feels both ancient and alive, where silver-grey Old Red Sandstone cliffs rise sharply above open pastures and the water shifts from deep blue to milky turquoise depending on the light.
The journey traditionally begins at Kate Kearney’s Cottage, a family-run establishment that has welcomed travellers since the 1860s, and finishes at Lord Brandon’s Cottage in the Black Valley. Whether you arrive on foot, by bicycle, or aboard a horse-drawn jaunting-car, the route rewards patience with constantly shifting perspectives of mountain, water, and sky.
History & Glacial Formation
The valley’s dramatic U-shape is a direct legacy of the last Ice Age. Roughly 20,000 to 25,000 years ago, a massive glacier advanced from the Black Valley, grinding through the bedrock and carving out a deep trough. As the ice retreated, meltwater filled the scooped-out depressions, leaving behind the five corrie lakes that define the route today: Coosaun Lough, Black Lake, Cushnavally Lake, Auger Lake, and Black Lough. The name Dunloe itself comes from Dún Lóich, meaning “fort of Lóich,” referencing a local chieftain mentioned in early Irish annals.
For centuries, the pass served as a vital trading route between the Killarney basin and the Brandon peninsula. It only became a major tourist destination in the Victorian era, when the rise of the grand tour brought visitors seeking Ireland’s wildest scenery. The tradition of horse-drawn jaunting-cars, which once carried locals and goods through the narrow track, evolved into a scenic transport method that remains a defining experience of the area.
What to See & Do
The Gap offers several ways to experience the valley, each with its own pace and perspective. Most visitors choose one of the following:
- Walking: The full 11 km point-to-point route follows the road and is graded as moderate. It takes roughly 2.5 to 3 hours one-way, with a cumulative elevation gain of around 350 metres. For a shorter option, a flat 2 km paved path leads from Kate Kearney’s Cottage to the Wishing Bridge and back, taking about 30–40 minutes and suitable for all ages.
- Jaunting-car rides: Traditional horse-drawn carriages carry up to four passengers along the narrow road. Drivers know the passing places intimately and will pause at scenic viewpoints. A one-way journey typically takes 1.5 to 2 hours and costs around €35 per person (or €140 for a private cart).
- Boat crossings: A steam-powered vessel operates seasonally between Ross Castle and Lord Brandon’s Cottage, cutting across the lakes and saving the walk or carriage ride. Departures usually run in the morning, with return trips in the early afternoon. Fares are approximately €25 per person.
- Cycling: The road is popular with cyclists, particularly those riding e-bikes from Killarney. The gradient is manageable but sustained, and the road surface is generally good. Bicycles can usually be transported on the boat, allowing for flexible routing.
Key landmarks along the way include the Wishing Bridge, a stone arch spanning the narrowest point between Coosaun Lough and Black Lake, and the Colleen Bawn Cottage, a modest stone shelter near the centre of the valley that provides a handy resting spot. At the southern end, Lord Brandon’s Cottage sits in the shadow of the Reeks, offering refreshments and panoramic views before the road climbs toward the Black Valley.
Navigating the Road & Seasonal Closures
The R568 that runs through the Gap is a single-track road with limited passing places. To protect the environment and ensure safety, the road is closed to private motor vehicles during daylight hours in peak summer months. Only pedestrians, cyclists, horse-riders, and licensed jaunting-cars are permitted during these periods. Outside of summer, cars may use the road, but drivers must yield at passing places and exercise caution on sharp bends.
If you plan to drive, aim for early morning or late evening, or consider parking at Kate Kearney’s Cottage and walking or cycling part of the route. The road is not recommended for inexperienced drivers, and visibility can drop quickly in fog or rain.
Practical Information
- Parking: Kate Kearney’s Cottage has a car park with roughly 30 spaces. Lord Brandon’s Cottage has a smaller lot that fills quickly in summer. Arrive early or use alternative transport.
- Facilities: Toilets, a café, and a craft shop are available at Kate Kearney’s Cottage. Lord Brandon’s Cottage offers a small shop and snack service. There are no public toilets along the road itself.
- Best time to visit: May through September offers the most reliable weather and full service schedules. Early mornings provide the clearest light for photography and fewer crowds.
- What to bring: Sturdy footwear, a waterproof layer, and a full water bottle. The valley offers little cover in sudden showers. Dogs are welcome but must be kept on a short lead at all times.
- Safety: The road is narrow and lacks hard shoulders in places. Cyclists should wear helmets and use lights, even in daylight. Walkers should stay on the paved edge and be visible to jaunting-car drivers.
Nearby Sights & Itineraries
The Gap of Dunloe is rarely visited in isolation. It sits within the wider Killarney area and pairs naturally with several nearby attractions:
- Ross Castle and the three Lakes of Killarney are a short drive from the northern entrance. Guided tours of the 15th-century tower house run seasonally.
- The Purple Mountain range on the eastern side offers several marked walking routes, including the popular Ladies View trail.
- Continuing south from Lord Brandon’s Cottage leads into the Black Valley, a dramatic mountain pass that eventually connects to Moll’s Gap and the Ring of Kerry.
- For a more remote mountain experience, the Brandon peninsula lies just beyond the Reeks, featuring the historic O’Donoghue’s Boyne House and the wild coastline of Brandon Bay.
A straightforward half-day itinerary involves arriving at Kate Kearney’s Cottage by mid-morning, taking the jaunting-car south to Lord Brandon’s Cottage, grabbing a coffee, and catching the return boat from Ross Castle in the early afternoon. For those preferring self-guided exploration, a steady walk from the northern entrance to the Wishing Bridge and back makes for a relaxed afternoon, easily combined with a visit to nearby Beaufort or the Killarney National Park visitor centre.
The Gap of Dunloe rewards visitors who move at a slower pace. Allow extra time for photo stops, check the seasonal boat and jaunting-car schedules before setting out, and keep an eye on the weather forecast – mountain conditions in Kerry can shift quickly.
