The Gap Looks Like a Shortcut. It Is Not.
The first time I drove the Gap of Dunloe, I met a jarvey coming the other way just past the Wishing Bridge. His pony did not hurry. I had to reverse nearly eighty metres back up the lane to the nearest passing place, the stone walls an inch from my wing mirrors, while a line of cyclists squeezed past on the verge. It was a Wednesday in June, about half nine in the morning. By eleven the road was a slow procession of walkers, horses, bikes and rental cars, all sharing a strip of tarmac barely wide enough for one.
That is the honest introduction you need. The Gap of Dunloe is one of the most dramatic mountain passes in Ireland, and the question of whether to drive it comes up constantly from cousins planning a Kerry road trip. The short answer is yes, you can drive the Gap of Dunloe by car: the road is public, paved and maintained by Kerry County Council. The longer answer is that it is not always the best way to see it, and for some visitors it is a genuinely poor idea.
This guide is for the ones who want to do it themselves. I will tell you what the road is really like, when it makes sense, when it does not, and how to avoid becoming the tourist the jarveys have to reverse around.
What the Gap of Dunloe Actually Is
The Gap of Dunloe is a narrow glacial breach running north-south between the MacGillycuddy's Reeks and the Purple Mountain Group in County Kerry. The road threads the valley floor for roughly eleven kilometres, from Kate Kearney's Cottage in the north to Lord Brandon's Cottage in the Black Valley in the south. The high point, known as the Head of the Gap, sits at about 241 metres above sea level, with around 200 metres of total climbing and descent along the way.
Within the pass are five lakes, connected by the River Loe: Coosaun Lough, Loch Dubh, Cushnavally Lake, Auger Lake and Black Lough. Between the first two you cross the Wishing Bridge, a small stone arch where local tradition says a wish made on the span will come true. The whole area is part of a Special Area of Conservation, so the land is protected, the verges are fragile, and the rules of the road matter more than usual.
For centuries the route was a working pass for locals moving between the Killarney basin and the Brandon peninsula. Tourism arrived with the Victorian grand tour and never left. Today the conflict is between that working heritage, the jarveys and their ponies, and visitors who see a paved road on the map and assume it behaves like any other.
The Route: Kate Kearney's to Lord Brandon's and Back
Most people start at Kate Kearney's Cottage on the northern side. There is a large free car park, a cafe, toilets and the jarvey rank where the jaunting cars line up from Easter through October. From there the road heads south into the mountains, climbing gently past the first lake and the Wishing Bridge before it squeezes through the narrowest section at the Head of the Gap.
The far end lands you at Lord Brandon's Cottage beside the Upper Lake in Killarney National Park. A few years ago the building itself was little more than a shell, but the location remains the hand-off point for one of the great traditional day trips in Kerry: through the Gap by foot, bike or jaunting car, then back across the Lakes of Killarney by boat to Ross Castle. If you drive the Gap one way, you either need someone to meet you at the far end or you have to come back the same road.
That return leg is where the frustration lives. Driving it southbound feels adventurous. Driving it northbound, against the flow of walkers and jarveys heading down from the Head of the Gap, can be a long exercise in reversing. Most cousins who drive it prefer an out-and-back early in the morning, or they leave the car at Kate Kearney's and complete the journey another way.
Driving It Yourself — The Honest Verdict
Let me be clear about the legal position first. The road through the Gap of Dunloe is a public road and you are entitled to drive it. A sign at Kate Kearney's Cottage suggests traffic is primarily restricted to horses, walkers, residents and business traffic, but this is not a legal closure. Lonely Planet and Kerry County Council have both confirmed the road is public. What the sign really signals is local preference, and that preference exists for a reason.
The road is single-track for much of its length, with stone walls or rock faces right up to the edge of the tarmac. Passing places are not frequent. Oncoming traffic can include farm vehicles, cyclists, hikers with poles, and the jarveys. Jarvey etiquette gives them the right of way, partly because a pony cannot reverse up a hill the way your hire car can. If you meet one in a tight spot, you are the one who reverses.
A compact car is a big advantage here. A large SUV or people carrier will make the tight sections harder and the reversing longer. The same applies if you are not fully comfortable driving on the left yet. The rules of the road in Ireland are only part of the challenge; the rest is reading the behaviour of everyone else sharing a very small space.
Timing and Traffic: When to Go
The Gap of Dunloe changes character completely depending on the clock and the calendar. In mid-summer between Easter and October, the daylight hours belong to walkers, cyclists and jaunting cars. Coaches cannot fit through the pass itself, but the organised tours still unload dozens of people at Kate Kearney's who then proceed on foot or by pony. The road becomes a shared promenade, and driving through it is slow, stressful and unwelcome.
| Time | What to expect | Recommendation |
|---|---|---|
| Before 09:00 | Quiet, possible mist, best light | Ideal for a self-drive |
| 09:00–10:00 | Jarveys and walkers begin to arrive | Still manageable |
| 10:00–16:00 | Busy with jaunting cars and hikers | Avoid driving |
| After 17:00 | Day-trippers leave, softer light | Good if you go slowly |
| November–March | Very quiet, short days, possible ice | Drive only in clear weather |
The best advice I can give is to treat it like a dawn mission. Leave Killarney by half seven, be at Kate Kearney's before eight, and you will have the pass almost to yourself. The light is better, the sheep are less bothered, and you can actually stop at the bridges without causing a tailback. If you arrive at eleven on a July Saturday, you have already made the wrong choice.
What You'll See Along the Way
The scenery is why people persist with the drive. Within a few minutes of Kate Kearney's the valley closes in. The road crosses the Wishing Bridge, then traces the edge of Loch Dubh, the Black Lake, where the water can look almost pewter under cloud. The stone bridges over the River Loe are natural stopping points, and the Head of the Gap gives you a view south into the Black Valley that makes the reversing almost feel worthwhile.
You will almost certainly see sheep on the road. You will see red deer on the higher slopes if you are quiet. You will see the full length of the MacGillycuddy's Reeks rising to the west and the rounded shoulders of Purple Mountain to the east. It is, by any measure, one of the most concentrated stretches of mountain scenery in Ireland.
The problem is that the driver rarely gets to look at it. The road demands attention. If you want to actually absorb the views, you need to be a passenger, or you need to stop. Stopping is fine when it is quiet; when it is busy, pulling over can block the whole pass.
Parking, Passing Places and Road Etiquette
The main car park at Kate Kearney's Cottage is free and holds around eighty vehicles, which sounds generous until you see it fill by eleven on a summer morning. There is no large alternative at the southern end, and the lane from the Black Valley is even narrower. If you are driving, Kate Kearney's is the sensible place to start.
Passing places work the same way they do on any Irish single-track road: pull in on the left if the space is on your side, or stop opposite a passing place if the space is on the other side so the oncoming vehicle can use it. The difference here is that the jarveys and walkers do not always follow that logic. A jarvey cannot reverse easily, so you reverse. A cyclist may not have anywhere to go, so you wait. Patience is the only fuel that works in the Gap.
Do not stop in the middle of the road for photographs, even if the view is sensational. Do not park on the verges outside the designated areas. The ground is boggy, the ecology is protected, and a stuck hire car is an expensive way to end a morning. If you want a photo, use a passing place or one of the small lay-bys, and only when traffic is light.
The Alternatives: Walk, Cycle or Jaunting Car
Discover Kerry and most local operators are frank about it: the best way to experience the Gap is not from behind a steering wheel. Walking gives you time at the Wishing Bridge and the lakes. Cycling gives you speed without the stress of sharing the road with a pony. A jaunting car gives you a jarvey who knows every bend and every soft verge, and the ponies are part of the landscape in a way your rental car never will be.
The simplest self-powered option is to walk from Kate Kearney's to the Wishing Bridge and back, roughly eight and a half kilometres return on a mostly level track. The full one-way walk to Lord Brandon's Cottage is about eleven kilometres and works best if you arrange the boat back to Ross Castle from the far end. That full circuit is one of the classic Killarney days, but it requires booking the boat in advance in peak season and a taxi or lift back to your car if you do not take the boat.
If you want the tradition without the driving, the jaunting cars leave from Kate Kearney's and run through the Gap to Lord Brandon's Cottage, where you can pick up the boat. Operators offer different combinations and prices change seasonally, so check current rates before you travel. None of this is included in a My Irish Cousin rental; it is simply the local experience that pairs well with having a car to reach Kate Kearney's in the first place.
How to Fit It Into a Kerry Road Trip
The Gap of Dunloe is not technically part of the Ring of Kerry loop, but it sits right beside it. From Killarney you can reach Kate Kearney's in under twenty minutes via the N72 and the Gap road. Count on at least two and a half hours for a careful out-and-back drive with a few stops, longer if you walk or take the boat. It is a half-day, not an hour-long detour.
My preferred Kerry day looks like this: start early at Torc Waterfall, drive through Muckross House and Gardens, then head to Kate Kearney's for the Gap. If you still have energy, loop back via Ross Castle and the Lakes of Killarney. The full Ring of Kerry self-drive is a separate day; trying to combine the two is how cousins end up driving in the dark.
For a wider Kerry itinerary, the Dingle Peninsula is another full day to the north, and the Beara Peninsula sits to the south. The Gap fits best as a Killarney-focused morning before you commit to the bigger loops.
Why the Right Rental Cover Matters on Roads Like This
This is the part where I talk about the car. Narrow stone-lined roads are unforgiving. A scrape on a wall, a chipped windscreen from a passing stone, a tyre pulled on a sharp verge: these are the kind of small incidents that become expensive arguments with a rental desk if you do not have the right cover. My Irish Cousin includes zero excess cover as standard, which means if something happens on a road like the Gap, you owe nothing extra. Tyres, glass, wing mirrors and call-out charges are all covered.
The other detail that matters is the car size. A compact or mid-size vehicle is easier through the Gap than a large SUV, and automatic transmission is worth considering if you are not confident with a manual on hills. My Irish Cousin offers both, and you can add a second driver at no extra cost if you want to share the workload on a long Kerry day.
The Final Word on Driving the Gap
The Gap of Dunloe is unforgettable, but it is not a relaxing scenic cruise. It is a working mountain pass shared with walkers, cyclists, sheep and jarveys. Driving it early in the morning, in a small car, with your mirrors tucked in and your patience ready, can be one of the highlights of a Kerry trip. Driving it at midday in July is a mistake you will not forget for the right reasons.
If you have the time, leave the car at Kate Kearney's and experience the Gap more slowly. Walk to the Wishing Bridge, take a jaunting car through the Head of the Gap, or cycle the length and catch the boat back. The mountains deserve your attention, and you will enjoy them far more when you are not calculating how many metres you need to reverse.
However you choose to do it, go slowly, yield to the jarveys, and remember that the best Kerry roads reward the early start. The Gap has been here since the last ice age. It will wait for you to arrive at the right time.
