Samhain (pronounced “Sow-wen,” with the sow sounding like that used to describe a female pig) marked the end of the harvest and the beginning of winter. Many traditions associated with Halloween today can be traced, at least in part, to these ancient celebrations.
Today, Halloween in Ireland is more about the remembrance of those ancient customs, even though costumes and trick-or-treating are very much a part of it as well.
Across the island, you’ll find spectacular festivals, bonfires, parades, storytelling, traditional Irish foods on offer, ghost tours and an abundance of family-friendly events, all part of the celebration of Halloween .
Some celebrations focus on Ireland’s ancient Samhain heritage, while others embrace the spooky side of Halloween with haunted attractions and plenty of thrills.
From the Púca Festival in County Meath, where visitors can experience Samhain traditions in the landscape where they originated, to the spectacular Derry Halloween celebrations, Ireland offers plenty of ways to experience Halloween.
Whether you’re planning a trip to Ireland in October or simply curious about the origins of Halloween, here’s where to find the best Halloween festivals, traditions and spooky experiences around the island.

Why is Ireland Considered the Home of Halloween?
In Ireland, Samhain marked the end of the harvest and the beginning of winter. It was one of the four major seasonal festivals in the Gaelic calendar.
Samhain was also considered a time when the division between the living world and the supernatural world was especially thin. According to traditional beliefs, spirits and otherworldly beings could cross into the human world around this time. As a result, people in ancient Ireland lit fires, gathered for celebrations, and used disguises or costumes as part of the traditions that we now know are associated with this festival.
Over time, Samhain traditions became intertwined with Christian observances such as All Saints’ Day and All Hallows’ Eve. The evening before All Saints’ Day became known as All Hallows’ Eve, which eventually evolved into the word “Halloween.”
Irish and Scottish immigrants later brought many Halloween customs with them when they emigrated to North America, where the holiday developed into the celebration we know today.
Where Can You Find the Origins of Halloween in Ireland?
Some of the most fascinating places to explore Ireland’s Halloween heritage are in the Boyne Valley in County Meath.
This area of Ireland is one of the most important places to explore the ancient roots of Halloween.
According to Irish folklore, Samhain was celebrated at the Hill of Tlachtga, now known as the Hill of Ward, near Athboy, more than 2,000 years ago.
The site is associated with an ancient Samhain fire festival and with the gathering of people for feasting and ceremonies at the beginning of winter. Archaeological research indicates that Tlachtga was indeed used for ceremonial activity and feasting from the Late Bronze Age through the early medieval period.
The Hill of Tara was one of Ireland’s most important ancient ceremonial and political sites, and Irish mythology associates it with gatherings and supernatural events at Samhain.
Other ancient monuments throughout the Boyne Valley that can be connected to Samhain include the Newgrange complex as well as the Loughcrew Cairns.
However, Rathcroghan in County Roscommon is one of the most under-rated places in Ireland to visit if you want to understand the ancient origins of Halloween.
Known in early Irish literature as Cruachan Aí, Rathcroghan was the ancient royal site of Connacht and is a vast archaeological landscape containing around 240 identified archaeological sites.
The monuments span more than 5,500 years of Irish history, from the Neolithic period through to the medieval era.
But Rathcroghan’s connection to Halloween goes much deeper than its archaeology.
The site is strongly associated with Samhain.
According to the Rathcroghan Visitor Centre, Samhain is particularly associated with Rathcroghan, and the landscape was believed to be a place where the boundary between this world and the Otherworld became easier to cross.
The complex includes Oweynagat (the Cave of the Cats), a cave traditionally connected with the Otherworld and supernatural beings.
It is sometimes described as Ireland’s “Gate to Hell.”
According to medieval Irish tradition, supernatural creatures emerged from Oweynagat at Samhain and caused destruction across the landscape as winter approached. The entrance to the cave itself is particularly interesting archaeologically, with two Ogham stones incorporated into its construction.
The cave is also associated with the Mórrígan, the powerful figure from Irish mythology, and Rathcroghan features prominently in the Táin Bó Cúailnge, Ireland’s great epic, including stories of Queen Maeve of Connacht.
Visiting these places will give you a very different perspective on Halloween. Rather than thinking of Halloween as a modern holiday filled with costumes and candy, you can begin to understand the ancient Irish traditions, beliefs and seasonal celebrations that helped shape what it is today.
Traditional Irish Halloween Customs
Traditional Irish Halloween Costumes
If you’re looking for an authentic Irish-inspired Halloween costume, you don’t necessarily need to reach for a green-and-orange outfit.
Traditional Halloween in Ireland was much more about disguise, masks and mischief.
Halloween, or Oíche Shamhna, which is the official Gaelic name for the holiday, was associated with the ancient festival of Samhain as mentioned earlier in this article, with beliefs about supernatural beings being particularly active at this time of year.
What Kinds of Masks and Disguises Were Worn?
There wasn’t one standard “traditional Irish Halloween costume.” Instead, people created homemade disguises and masks, often using whatever materials were available to them.
The goal was to make themselves look strange, frightening or unrecognizable.
The National Museum of Ireland Country Life outside Castlebar in County Mayo has examples of traditional Halloween masks as part of its National Folklife Collection. You’ll find them in its Samhain section.
Guising and Halloween Mischief
The Irish tradition of guising has similarities to modern trick-or-treating.
Groups of children and adults would disguise themselves and go from house to house, where they might sing, tell stories, perform a trick or provide some form of entertainment in exchange for food or treats, and in later years, for money.
They also went around disguised to both frighten and entertain their neighbors, helping establish some of the customs that eventually evolved into the modern-day Halloween celebrations that we are familiar with.
The festivals listed below are the most popular, but there are many more smaller celebrations across the country.
The Púca Festival, County Meath (Oct. 29-Nov. 1)
There’s probably no better place to celebrate Halloween than in Ireland’s Boyne Valley region, where Samhain was once celebrated with grand fires and feasts.
This 4-day festival is a popular annual celebration of Halloween that draws locals and international visitors and is based on the legend of the púca, a shape-shifting creature from Celtic folklore and a familiar character in the Irish Halloween story.
The festival will include, as usual, a number of free and ticketed events, all focused on “music, myth, food, folklore, fire, feasting and merriment.”
This year’s theme is called “Between Worlds,” which celebrates the threshold of Samhain when the modern world quiets down and the former mystical traditions come alive.
All of the events are centered around the towns of Trim and Athboy.
Highlights of this year’s festival include the Púca procession, the traditional lighting of the Samhain fire, light projections on Trim Castle, and The Pyro Collective, all free events.
The Samhain Circus is another distinctive experience that is way different to a traditional circus that you might be familiar with.
Held in Athboy, it includes a theatrical performance that highlights the darker, more mischievous side of Halloween.
Púca’s Samhain Circus is an adults-only experience, while the festival as a whole includes events suitable for families and free public events such as the Púca Procession and Samhain Fire
There’s a lot to entertain everyone at this hugely popular Halloween event that will also include fire displays, a harvest market, workshops, games, and more.
A schedule of events can be found on the Púca Festival website.
Derry Halloween Festival (Oct. 28-31) Celebrates its 40th Anniversary
If you want to experience Halloween on a truly spectacular scale, put the Derry Halloween Festival in Northern Ireland on your list.
The historic walled city comes alive with ghosts, ghouls, mythical creatures, performers and thousands of costumed visitors during one of the biggest Halloween celebrations in Europe.
This year is particularly special because festival organizers are celebrating its 40th anniversary, taking place from Oct. 28th through Nov. 1st.
What began as a local fancy-dress event has grown into an internationally recognized festival that attracts tens of thousands of visitors each year.
The festival combines the ancient traditions of Samhain with modern Halloween entertainment, making it different from the Púca Festival mentioned above.
Derry’s historic walls also provide a dramatic backdrop for spectacular light installations, theatrical performances, acrobatics, music and street entertainment.
One of the highlights of the festival each year is the Awakening the Walled City Trail, where visitors can explore the atmospheric streets and historic walls after dark over three nights, while encountering illuminated installations, performers and mythical characters along the way.
There are also family-friendly events, tours, trails and entertainment for younger visitors. If you’re traveling with kids, you might want to bring them to Little Horrors, where they can celebrate with some arts and crafts Halloween style.
The festival reaches its climax with the famous Halloween Carnival Parade, when thousands of costumed revelers fill the streets before the evening ends with a spectacular fireworks display over the River Foyle.
You’ll find a full schedule of festival events here.
Is Derry Halloween suitable for families?
Yes. Although there are plenty of spooky and frightening elements to the festival, Derry Halloween isn’t just for adults.
If you’re traveling with children, check the individual event descriptions before booking, as some of the evening entertainment and haunted attractions are intended for older visitors.
Why visit Derry for Halloween?
Derry offers something different from the more history-focused Púca Festival in County Meath.
Púca places greater emphasis on the ancient origins of Samhain, while Derry combines that heritage with a huge contemporary celebration featuring costumes, street performances, music, fireworks and a spectacular carnival atmosphere.
You don’t have to spend your entire visit at the festival.
Derry’s historic walls, museums, architecture and lively food and music scene make it worth adding a few extra days to your itinerary.
Tip: Accommodation can become difficult to find during the Halloween celebrations, so book well ahead if you plan to visit.
The Bram Stoker Festival, Dublin (Oct. 31-Nov. 3)
The popular Bram Stoker Festival returns to Dublin in 2026 from Oct. 23rd through the 26th for four days and nights of “deadly adventures,” with events for both gothic enthusiasts and families.
The celebration pays homage to Bram Stoker, the Dubliner who created the novel “Dracula,” which was first published in 1897, and draws inspiration from Stoker, his life and work, all the while celebrating the Gothic, the supernatural, the after-dark and what Dublin might have been like during the Victorian era.
The festival also explores the darker side of Irish history, mythology and folklore, making it a good choice if you’re interested in the stories behind Ireland’s supernatural traditions.
Previous programs have included haunted walking tours of Dublin’s dark side, specifically sites most closely associated with Stoker, including Marsh’s Library, Trinity College, and Dublin Castle, as well as explorations of Irish mythology, Gothic performances, horror films, live music and family-friendly events, making this Dublin Halloween-related festival a good all-round multidisciplinary arts event.
Tip: The 2026 program is due to be announced in late September, so check the official festival website before planning specific events.
Some events sell out, while others are free or family-friendly.
Macnas Halloween Parade, Galway (Oct. 25)
If you’re looking for one of Ireland’s most spectacular Halloween experiences, don’t miss the Macnas Halloween Parade in Galway, part of Galway City’s “Gaillimh Ah-Boo! initiative.
This isn’t your typical Halloween parade.
Macnas is Galway’s renowned performance and spectacle company, with parades that transform the city streets with enormous puppets, elaborate costumes, music, fire and theatrical performances inspired by mythology, folklore and the imagination.
Each year, Macnas comes up with a different theme for its spectacular event, and on this, the company’s 40th anniversary, the theme of its 2026 parade is “Fiáin” (pronounced Fee-awn).
“Fiáin” is meant to be a celebration of the wild elements of the West of Ireland and according to the company organizers, it also reflects “the wild inspirations that have imbued our work over the last 40 years, and the wild energy that engulfs the streets, performers and audiences as we own the streets and public spaces for one night only.”
The Oct. 25th event (still to be confirmed, however) is expected to begin at 5:30 p.m., with the parade as usual making its way through Galway city, bringing thousands of spectators onto the streets for a dramatic evening of outdoor theater and spectacle.
Macnas’ performances often draw on Ireland’s rich tradition of mythology, folklore and storytelling. Rather than simply focusing on ghosts and monsters, the parade creates an imaginative world of larger-than-life characters and creatures.
If you’re in Ireland during this time, I’d absolutely put Galway on my itinerary as the city celebrates Halloween in a big way.
What Makes the Macnas Parade Special?
The scale of the spectacle is what sets Macnas apart.
Giant puppets and fantastical figures move through the city accompanied by performers, musicians and dramatic visual effects.
It is truly an immersive experience rather than something you simply watch from the sidelines.
The parade is free to attend.

Halloween in Limerick: Samhain, Folklore and Fire
Limerick offers a different way to experience Halloween in Ireland, combining the ancient traditions of Samhain with contemporary theater performances, storytelling sessions, fire performances and family-friendly events.
In 2025, the city was one of Fáilte Ireland’s Home of Halloween destination hubs, with an array of Halloween events on offer throughout the month of October.
On Oct. 22, Limerick will kick off its Hallowe’en Festival. One of last year’s highlights was the Lumen Street Theatre’s Fire and Shadows Procession, with illuminated supernatural figures, mythological characters and theatrical fire performances filling the city’s medieval streets.
While no formal schedule has been released yet, expect storytelling, folklore talks, theatrical performances, Halloween trails and other family activities.
The nearby Lough Gur, an area rich in prehistoric archaeology, will also feature Halloween-themed events.
Halloween in Longford: Dead of Night Festival
If you’re looking for a Halloween experience that combines Irish folklore, mythology, fire and storytelling, County Longford in Ireland’s Midlands region is worth considering.
This year, Longford is part of the Ireland: Home of Halloween program, alongside neighboring County Westmeath, with regional program known as Samhain in the Heartlands.
The centerpiece of Longford’s Halloween celebrations is the Dead of Night Festival, a county-wide celebration that includes live performances, interactive experiences, themed attractions and atmospheric storytelling.
One of the main highlights is the Fire & Shadows Procession in Longford Town.
The spectacular Halloween-night procession is expected to feature fire dancers, drummers, giant puppets, mythical creatures and other performers.
You might also find lantern and mask-making workshops, storytelling sessions, harvest celebrations, walking tours, spooky drives, family activities and live music.
I would check out this list of events on the Longford tourism website.
What Else Can you Experience in Longford Around Halloween?
The Halloween program extends beyond Longford Town.
One notable event takes place at the Corlea Iron Age Roadway and Trackway Visitor Centre, an interesting attraction that you should definitely visit on your way across the Midlands.
The annual Féile na Samhna celebrations explore the area’s ancient landscape, folklore and connection to Samhain.
Oher Halloween events include the Samhain Trail and the Spooktacular Summoning at Dún na Sí, a new Samhain procession in Athlone that includes a range of food, storytelling, cultural and heritage experiences.
If you’re traveling through Ireland in late October, Longford could be an interesting stop for experiencing a more distinctly Irish side of Halloween, especially if you’re interested in Samhain, folklore and storytelling rather than simply haunted attractions.
Kilkenny Halloween/Samhain Events
Kilkenny is not only one of the most popular cities in Ireland for tourists but also an atmospheric place to experience Halloween given its medieval streets and tales of witchcraft and dark history.
Kilkenny is also one of the destinations included in Ireland’s Home of Halloween initiative, with events taking place throughout the month. The celebrations, known as “Fire, Feast and Folklore,” will include storytelling sessions, fire performances, family activities, food and plenty of opportunities to explore the city’s darker side.
One of the highlights in Kilkenny this year will be a new outdoor show that will include The Cailleach, a Macnas creation.
In Gaelic mythology and folklore, the Cailleach is a powerful female associated with winter, wild landscapes and the changing seasons.
The date for the show has not been released but expect a spectacle similar to that in Galway’s Halloween celebrations.
Savour Kilkenny, the city’s popular October food festival, is another great reason to visit Kilkenny around this time.
The festival, scheduled to take place between Oct. 22nd and 26th, will include food markets, cookery demonstrations, family entertainment and other events around Kilkenny Castle.
