Where the Irish Open is played: course guide for bettors

There is no single "Irish Open course". That is probably the most important thing to understand about the tournament.

Since 1927, the event has moved between exposed seaside links, inland links-style layouts and tree-lined parkland courses. A golfer trying to control the ball through Atlantic wind at Royal County Down is facing a different test from someone attacking the Palmer North course at the K Club.

The 2026 Amgen Irish Open pushes that contrast to the extreme. The tournament has moved from The K Club, Straffan, County Kildare, to Trump International Golf Links, Doonbeg, an exposed links on the County Clare coast.

That change matters if you are comparing players. Our wider golf betting in Ireland guide explains why course fit matters, while the 2026 Irish Open betting guide covers this week's field and markets.

Where is the 2026 Irish Open being played?

Doonbeg hosts the Irish Open for the first time in 2026.

The course originally opened in 2002 after being designed by Greg Norman. Dr Martin Hawtree later carried out a major redesign, and further changes were made ahead of this year's championship.

There is one detail worth clearing up because two sets of course numbers appear online.

For normal resort play, Doonbeg is a par 72 measuring 7,026 yards from the back tees.

For the 2026 Irish Open, the DP World Tour has set it up as a par 70 measuring 6,838 yards.

Those are not contradictory descriptions of the same tournament setup. The Tour has altered the configuration for championship week.

The tournament routing is a single loop, with nine holes heading out and nine returning. The front nine generally plays with the prevailing wind. The back nine plays mostly into it.

That gives the round a natural change of character. A golfer can reach the turn after spending much of the opening stretch working with the breeze, then face a more demanding run home as the same wind becomes resistance.

What changed at Doonbeg for the Irish Open?

The opening and closing holes received the biggest revisions.

The first tee was moved towards the coastline, changing the opening hole from a relatively straight par five into a sweeping dogleg left.

The 18th was rebuilt much more substantially. It is now a 462-yard uphill par four that finishes at an elevated, undulating green. Bunkers affect both the tee shot and approach, and the hole usually plays into the prevailing wind.

That makes 18 far more than a finishing backdrop. A one-shot lead arriving there is exposed to a proper final test.

The par threes are another part of the course where the scorecard can be misleading. The 14th measures only 137 yards in the tournament setup, but it plays into the wind. The course superintendent has explained that the same hole can ask for a wedge in calm weather and something closer to a six iron when the breeze gets up.

This is the useful part of course analysis for betting. Yardage on its own does not tell you how long a links hole actually plays.

What type of golfer does Doonbeg reward?

No course guarantees one player profile will succeed, but Doonbeg makes some skills harder to hide than others.

Controlling ball flight

Wind changes both distance and shape. A golfer who launches everything on the same high trajectory has fewer options when the breeze becomes strong.

Being able to flight an iron lower, take spin off an approach or work the ball into the wind can become more useful here than on a sheltered parkland course.

Judging bounce and run

Links golf does not always let a player fly the ball directly to a number and expect it to stop.

Firm ground, contours and wind can all affect where the ball finishes after landing. That places more value on judging the ground as part of the shot.

Recovering from uneven misses

Dunes do not produce tidy, flat rough.

A drive can finish on an awkward stance, against a dune face or in native grass. The quality of the next shot can matter as much as the initial mistake.

Staying patient when the weather changes

The conditions do not have to be identical for every group.

A player can hit almost the same shot on Thursday and Friday and get a completely different result because the wind has changed speed or direction. That makes links experience useful, but it does not make previous links success a guarantee.

For more on the current field rather than the course itself, our Irish Open betting guide looks at the players facing this setup.

How many courses have hosted the Irish Open?

Across the full history of the championship, the Irish Open has visited 22 different venues through the 2026 staging.

You may also see the DP World Tour describe Doonbeg as the tournament's 19th different venue. That count refers to the DP World Tour era since the event returned in 1975, not the entire history going back to 1927.

Portmarnock remains the runaway leader with 19 stagings.

The K Club is already confirmed to host again in 2027, which will take it to four Irish Opens.

If you want the winners attached to those courses rather than the course characteristics, our Irish Open past winners guide has the full year-by-year table.

Portmarnock: the historical home

No venue is as closely tied to the Irish Open as Portmarnock.

The Dublin links hosted the first championship in 1927 and has staged the event 19 times, more than three times as often as any course other than Royal Dublin.

Its Irish Open winners alone read like a piece of European golf history: George Duncan, Fred Daly, Ben Crenshaw, Hubert Green, Seve Ballesteros, Bernhard Langer, Ian Woosnam and José María Olazábal all won there.

Michael Campbell was the most recent, taking the 2003 title in a play-off.

Portmarnock is a true links built on a narrow stretch of duneland. Exposure to the elements is part of the test, but its reputation is not built around gimmicks or one signature hazard. The challenge comes from shot placement, angles and how the wind changes otherwise fair golf holes.

For bettors, that is an important distinction. "Links form" is useful as a broad category, but a player who suits one links course does not automatically suit every other one. Portmarnock, Doonbeg and Royal County Down all use coastal terrain differently.

Royal County Down: narrow, wild and punishing

Royal County Down is visually dramatic, but the course's difficulty is more useful to understand than the scenery.

Its Championship Links runs through the Murlough Nature Reserve beside Dundrum Bay. Narrow fairways weave between large dunes. Heather and gorse punish misses, while deep bunkers with overhanging faces can turn a small mistake into a recovery problem.

The greens can be fast and domed, which means approaches that miss their number do not always stay near the putting surface.

Traditional links shots also remain relevant. The club itself specifically points to the bump-and-run as an important part of playing the course.

Royal County Down has hosted five Irish Opens.

The latest was in 2024, when Rasmus Højgaard closed with a 65 and birdied four of his final five holes to beat Rory McIlroy by one. McIlroy had led by two with four to play.

That finish is a good example of why a difficult course does not always produce a defensive final round. A golfer can still attack it if the execution is good enough.

The K Club: a completely different Irish Open

The K Club is almost the opposite of Doonbeg.

Palmer North is an Arnold Palmer designed parkland course in County Kildare. It hosted the Ryder Cup in 2006 and the Irish Open in 2016, 2023 and 2025.

It also gets the tournament back in 2027.

McIlroy clearly likes it. Both of his Irish Open victories came here.

His 2016 win came by three strokes after an eagle, par, birdie finish. The 2025 version was much messier. He needed a 28-foot eagle on 18 just to catch Joakim Lagergren, then survived three extra holes before Lagergren finally found the water.

That does not make the K Club a "McIlroy course" in any useful predictive sense. Vincent Norrman won there in 2023.

What it does show is how different the Irish Open can look from year to year. The visual targets, turf, hazards and wind exposure at a parkland Palmer design are a long way from the questions Doonbeg asks in 2026.

Ballybunion: only one Irish Open, but a serious links test

It almost seems strange that Ballybunion's Old Course has hosted the Irish Open only once.

That came in 2000, when Patrik Sjöland won by two strokes.

The Old Course runs through natural dunes on the County Kerry coast. It is virtually treeless, heavily contoured and open to Atlantic conditions.

The betting relevance is fairly direct. Placement and trajectory matter because the ball has to deal with both the land and the wind. Flat lies are not guaranteed, and the natural contours can move a seemingly good shot away from its intended target.

This is not a course where "7,000 yards" or any other raw number would tell you much by itself.

County Louth: the course behind Lowry's amateur win

County Louth Golf Club at Baltray has hosted twice, in 2004 and 2009.

The second of those is the famous one.

Shane Lowry arrived as an amateur making his DP World Tour debut and left with the Irish Open trophy after beating Robert Rock in a play-off.

Baltray is a genuine east coast links. Tom Simpson and Molly Gourlay redesigned it in 1938, and the championship course now measures 7,031 yards from the back tees at par 72.

The routing is part of the challenge because the holes move in different directions. A wind that helps on one can become a crosswind or headwind shortly afterwards.

Strategic bunkering, rolling dunes and exposed ground put more emphasis on choosing where to miss rather than simply hitting the ball as far as possible.

Lowry's 2009 win is also a useful warning against overconfidence in course-profile analysis. He had almost no professional record to study because he was still an amateur. Sometimes a player simply produces a week nobody's model had enough evidence to predict.

Carton House: links ideas without the coastline

Carton House is the interesting middle ground.

Its Montgomerie course is described by the resort as an inland links rather than a traditional seaside links. Colin Montgomerie designed it with wide fairways and large, deep bunkers, and it measures 7,301 yards at par 72 from the blue championship tees.

It hosted the Irish Open in 2005, 2006 and 2013.

Stephen Dodd won a play-off there in 2005. Thomas Bjørn followed in 2006, and Paul Casey won by three in 2013.

Calling it "links" does not mean you should treat it like Doonbeg or Royal County Down. It borrows visual and strategic ideas from links golf, particularly its bunkering and open feel, but it does not have the same coastal wind or Atlantic ground conditions.

That distinction is useful whenever course labels get reduced to one word.

Adare Manor: old Irish Open history, new Ryder Cup course

Adare Manor, County Limerick, hosted the Irish Open in 2007 and 2008.

Pádraig Harrington won the first of those in a play-off against Bradley Dredge. Richard Finch won the following year by two.

There is an important catch if you are trying to carry those results into future golf analysis.

The current Adare Manor course is not the same design those Irish Opens used.

Tom Fazio fully redesigned and rebuilt the golf course in 2016 and 2017. The modern version is a championship parkland layout framed by mature trees and the River Maigue.

It will host the 2027 Ryder Cup.

So Harrington's 2007 Irish Open victory is part of the venue's history, but it should not be treated as direct course form for the version players will face in the Ryder Cup twenty years later.

That is exactly the kind of historical detail that sounds useful until you look closely at what changed.

Links golf vs parkland golf

The Irish Open moves between course types often enough that it is worth separating them properly.

These are tendencies, not rules.

Royal County Down and Doonbeg are both links courses, yet they do not ask exactly the same questions. The K Club and Adare Manor are both parkland courses, but they are not interchangeable either.

Why changing course changes the betting picture

The most obvious mistake is treating "Irish Open form" as though it means one thing.

Take the last three completed editions.

Vincent Norrman won at the K Club in 2023.

Rasmus Højgaard won at Royal County Down in 2024.

Rory McIlroy won back at the K Club in 2025.

Those are two different course types inside three years.

Now the event has moved again, this time to Doonbeg.

A player's previous Irish Open finishes can still tell you something about how they handle the event, crowds and pressure. But the predictive value of a finish should be separated from the course where it happened.

McIlroy winning the 2025 Irish Open does not mean he has already won at Doonbeg. Lowry winning at Baltray in 2009 does not mean all links courses suit him identically.

The useful question is more specific: what was the course asking when that result happened, and how similar is that to the test now?

That is why the Irish Open past winners page and the course guide work better together than either one does on its own.

What about first-round leader betting?

Course and weather can matter even more over one round than over four.

An outright tournament gives players several days for conditions to even out. First-round leader betting is settled after Thursday alone.

If the morning wave gets calm conditions and the afternoon groups face a strong Atlantic wind, those golfers have effectively played different versions of the same course.

Doonbeg is particularly exposed to that possibility.

It does not mean you can predict the weather perfectly or automatically find an advantage from the tee sheet. It means a first-round market is more sensitive to short-term conditions than the tournament outright.

The golf betting in Ireland guide explains how the first-round leader market differs from the outright.

Where will the Irish Open be played in 2027?

The tournament returns to the K Club in 2027.

That staging is already part of a long-term agreement that gave Palmer North the 2023, 2025 and 2027 Irish Opens.

It will therefore be the fourth Irish Open at the K Club, following McIlroy's win in 2016, Norrman's in 2023 and McIlroy's second title in 2025.

Do not confuse that with the Ryder Cup.

The 2027 Ryder Cup is at Adare Manor, not the K Club. The K Club's Ryder Cup was in 2006.

That distinction will matter increasingly as both events get closer and searches around Irish golf venues begin to overlap.

Frequently asked questions

Where is the Irish Open played?

The Irish Open does not have one permanent venue.

It has been played at 22 courses across the island of Ireland since 1927. The 2026 tournament is at Doonbeg in County Clare.

Is Doonbeg par 70 or par 72?

Both figures can be correct depending on which setup you mean.

The normal resort course is listed as par 72 and 7,026 yards from the back tees. The DP World Tour's 2026 Irish Open setup is par 70 and 6,838 yards.

For the tournament, use the Tour setup.

Which course has hosted the most Irish Opens?

Portmarnock has hosted the tournament 19 times.

It staged the first Irish Open in 1927 and most recently hosted in 2003.

Where is the 2027 Irish Open?

The 2027 Irish Open is scheduled for the K Club's Palmer North course in County Kildare.

It will be the venue's fourth staging of the championship.

Has Adare Manor hosted the Irish Open?

Yes.

Adare Manor hosted in 2007, when Pádraig Harrington won, and 2008, when Richard Finch won.

The course was later completely redesigned and rebuilt by Tom Fazio, so the modern course set to host the 2027 Ryder Cup is materially different from the version used for those Irish Opens.

Is Royal County Down a links course?

Yes.

Royal County Down is a traditional coastal links beside Dundrum Bay. Its narrow fairways run through dunes, heather and gorse, with deep bunkers and fast, often domed greens.

Why does the Irish Open change venue?

The tournament has historically rotated between leading courses around Ireland rather than using a permanent home.

That is part of why comparing Irish Open results requires context. A good finish at a parkland course does not automatically translate to an exposed links the following year.

Safer gambling

Course research can explain what a golfer is being asked to do, but it cannot turn a tournament into a predictable event. Weather changes, players have bad days and even a course that appears to suit someone can produce the opposite result.

Set a limit before betting and do not chase losses because the course or weather developed differently from expected.
