Driving It Yourself, from Cork

Yes, comfortably, in a day — and it is about 350 km round trip with five to six hours at the wheel.

Here is the honest version, including the parts that argue against driving at all.

The distances

Cork to Killarney is about 86 km, roughly an hour and a quarter on the N22 through Ballincollig, Macroom and Ballyvourney. Killarney is where the Ring conventionally starts.

The loop itself is 179 km. Pure driving time is genuinely disputed: some sources say two and a half hours, others three and a half. With stops, the consensus is seven to ten hours — in other words, a full day.

Add the return leg and a Cork-based self-drive day is roughly 350 km. That is not extreme, but it is a long time at the wheel on roads that demand attention.

One caution on sourcing: we could find no Fáilte Ireland or Discover Ireland published driving duration for the Ring. The only official duration guidance from the tourism boards is for the Ring of Kerry cycle route — a different 216 km route they suggest spreading over a week. Anyone quoting a tourism-board driving figure at you is probably quoting that by mistake.

Is it actually a difficult drive?

Less difficult than its reputation, and the difficulty is not where people expect.

The N70, which carries most of the loop, is a paved two-lane national secondary road. It is narrow in places with sharp bends, but it is a normal road. Drivers who have done it repeatedly report that it was widened and straightened with EU funding, and that head-on coach encounters are much less of a problem than they were a decade ago.

The genuinely narrow driving is on the detours — the Skellig Ring, the lanes into Portmagee, the road down to Derrynane. Coaches cannot use the Skellig Ring at all, which is exactly why it is quiet and exactly why it is tight.

We looked for official road-safety guidance specific to this route and found none — no RSA or TII advisory for the Ring of Kerry. What does exist is the county council’s one-way scheme, which is itself an official acknowledgement that the narrow sections congest.

Clockwise or anticlockwise — and the bit almost nobody mentions

The standard advice you will read everywhere is drive it clockwise, against the coaches, so you are never stuck crawling behind one with nowhere to pass.

It is a real argument, made by people who have driven it. The counter-argument is also real: going anticlockwise, with the flow, you never meet a coach head-on on a blind bend, and if you start early you are ahead of them anyway.

Here is the part the travel pages leave out. Kerry County Council operates a signed one-way traffic-management scheme asking all traffic — not just coaches — to run the Ring anticlockwise from Killarney.

So the single most-repeated tip on the internet runs against the county’s own posted request.

That does not make clockwise illegal. The scheme is advisory: the council asks, describes it as a trial, and keeps the road two-way for local access, and we found no statutory instrument behind it. Plenty of experienced drivers still go clockwise deliberately. But you should know you are choosing against a posted request, not into a neutral gap — and that the oncoming coach driver is expecting the road to be one-way.

Our own view: start early and go anticlockwise. Before about ten in the morning the convoy has not formed, which removes the entire reason for the clockwise trick.

The direction question in full, including which side of a coach to sit on if you change your mind and book one.

If you are driving on the left for the first time

Most of the people asking this are North American, so, specifically:

Your licence is fine. The Road Safety Authority states that a visitor may drive on a licence from any state outside the EU/EEA for up to one year, provided it is current and valid. The US Embassy in Dublin says the same. No International Driving Permit is required for a valid US licence.

One conflict worth flagging honestly: at least one widely-read travel site claims the RSA requires an IDP for US licence holders, while conceding the official wording is unclear. We could not find that requirement on the RSA’s own pages. Rental companies set their own rules regardless, so ask yours.

Book an automatic early, and expect to pay for it. Manual is the default in Ireland; automatics are a minority of the fleet, cost materially more, and sell out in summer. This is the single most common self-drive planning mistake.

Check the age rules. Most Irish rental firms want drivers 25 or over; some rent from 21 with a daily surcharge, and many apply an upper limit around 75. Several also require the licence to have been held for a minimum period.

Parking and stops

Ladies View is free — it sits inside Killarney National Park, and the park authority states that parking within the park is free. There is a second car park just up the road with the Upper Lake view.

Moll’s Gap has a car park opposite the shop and signed pull-offs; we found no published fee, and no official confirmation it is free either. It sits on a tight bend, so it fills and empties awkwardly.

The Kerry Cliffs charge, commonly quoted at about €5 per person including parking, paid at a booth in the car park. That figure is not published on the cliffs’ own site, so treat it as approximate. They are open roughly 9:30 to 18:30, and the operator’s own site warns that opening hours depend on the weather — there is currently a live notice to that effect. Check the day before.

The binding constraint at all three is capacity, not cost. In July and August the main car parks fill by mid-morning.

When not to do it

In deep winter, daylight is the problem, not the road. Kerry gets roughly seven and a half to eight hours of daylight around the December solstice — sunrise near 08:20, sunset near 16:20. A 179 km loop with stops does not fit comfortably inside that, and Met Éireann rates December the dullest month, with the west getting less sunshine than the east.

In July and August, expect the car parks full by mid-morning and coach traffic concentrated between about 10am and 4pm.

And if the driving itself is the thing you are dreading, book the coach. That is the one advantage it has that nothing else replicates: the vehicle everybody else is stuck behind is the one you are sitting in.

The Cork departures are here — including the honest note that the most-booked one is the lowest-rated of them.
