Halloween as we know it today has its roots in Ireland.

The ancient Celtic festival of Samhain — celebrated on the last night of October as the boundary between the living world and the spirit world grew thin — originated on this island more than two thousand years ago. It was brought to North America by Irish emigrants in the nineteenth century, where it eventually became the global phenomenon it is today.

Which means that when you celebrate Halloween in Ireland, you are celebrating it in the place where it all began.

In 2026, there is no shortage of ways to mark the occasion. From major festivals in County Meath to lantern parades, ghost tours, pumpkin patches, and atmospheric walks across the country, here is a guide to the best Halloween events in Ireland this October.

Púca Festival 2026 — County Meath

If you are looking for the single most atmospheric Halloween event in Ireland, Púca Festival in County Meath is the one to know about.

Taking place across the historic towns of Trim and Athboy from 29 October to 1 November 2026, Púca is a four-day celebration of Samhain, Irish mythology, fire, music, storytelling and the ancient traditions that gave Halloween its shape. The festival is held in the ancient Samhain homeland — the part of Ireland where the festival originated — which gives it a sense of place and meaning that few events can match.

Expect dramatic fire performances, large-scale outdoor spectacles, live music, comedy, circus acts, family-friendly events and free public programming across both towns. The backdrop of Trim Castle — the largest Anglo-Norman castle in Ireland — adds to the atmosphere considerably, particularly after dark when the castle is illuminated and the town fills with performers and visitors.

Púca is free to attend for most events, with ticketed evening shows available separately.

If you are planning to stay overnight in the area, our accommodation guide has options across Meath and the surrounding counties.

Derry Halloween — County Derry / Londonderry

Derry Halloween is one of the longest-running and most celebrated Halloween festivals in Europe, and it consistently draws visitors from across Ireland and beyond.

The city of Derry transforms itself entirely for the occasion, with the historic walled city providing one of the most dramatic settings imaginable for Halloween celebrations. The festival typically runs across the final week of October, building to a major carnival parade on 31 October that winds through the city streets.

The parade itself is spectacular — thousands of costumed participants, elaborate floats, fire performers, drummers and street theatre filling the medieval streets of the city. The atmosphere in Derry on Halloween night is unlike anywhere else in Ireland.

Alongside the parade, the festival includes outdoor concerts, fireworks, family events, ghost tours of the city walls, and a packed programme of free and ticketed events throughout the week.

Derry Halloween 2026 runs from 26 to 31 October. The city is compact and walkable, and the walled city area is the heart of the action.

Bram Stoker Festival — Dublin

Bram Stoker Festival celebrates Dublin's most famous horror writer and the city's gothic literary heritage across the Halloween weekend.

Bram Stoker, author of Dracula, was born in Clontarf in Dublin in 1847, and the festival that bears his name has grown into one of the most distinctive events in the city's cultural calendar. Taking place across 29 October to 1 November 2026, the festival blends literary events, immersive theatre, outdoor spectacles, walking tours, film screenings and late-night events across Dublin city centre.

Highlights typically include a Stoker's Séance immersive experience, gothic-themed walking tours of the city, outdoor performances, and a programme of events that ranges from family-friendly afternoon activities to atmospheric late-night shows.

Many events are free, with ticketed experiences available for the more immersive programming. The festival is centred around Dublin's city centre, with events taking place in venues, parks and public spaces across the area.

It is one of the more culturally rich ways to spend Halloween in Ireland — particularly for anyone with an interest in literature, gothic fiction or the history of horror.

Jack B. Yeats Halloween Festival — Sligo

Sligo has a strong claim to being one of Ireland's most atmospheric towns at Halloween, and the Jack B. Yeats Halloween Festival leans into that atmosphere fully.

Sligo is deeply connected with Irish mythology and the supernatural — W.B. Yeats drew heavily on the folklore of the Sligo landscape throughout his work, and the county has a strong tradition of ghost stories, fairy tales and ancient sites associated with the otherworld.

The festival takes place across the Halloween weekend and includes lantern parades, storytelling events, ghost walks, live music, family activities and outdoor performances. The town centre and surrounding areas provide a genuinely atmospheric backdrop, particularly in the evenings.

Sligo is also an excellent base for exploring the wider northwest — Glencar Waterfall is a short drive from the town and is particularly beautiful in autumn, while the surrounding countryside has a moody, dramatic quality that suits the season well.

Macnas Halloween Parade — Galway

Macnas is one of Ireland's most celebrated performance companies, known for their extraordinary large-scale outdoor spectacles that combine puppetry, music, fire and storytelling on a genuinely epic scale.

Their annual Halloween parade through Galway city is one of the most visually stunning events in the Irish calendar. Giant puppets, fire performers, drummers, dancers and hundreds of costumed participants fill the streets of Galway in a procession that is unlike anything else you are likely to see.

The parade typically takes place on the Sunday before Halloween and is free to attend. It draws enormous crowds, so arriving early to secure a good viewing spot is advisable.

The parade route winds through Galway city centre, and the atmosphere in the city on parade night is electric. Even if you have seen it before, it is the kind of event that rewards repeat visits.

Galway is a lively city at any time of year, but the combination of the Macnas parade and the general Halloween atmosphere in the city makes late October a particularly good time to visit. Our food and drink guide has recommendations for where to eat and drink in the city.

Ghost Tours & Spooky Walks

Beyond the major festivals, Halloween is a good time to explore Ireland's many ghost tours and atmospheric walking routes.

Kilkenny has one of the best reputations for ghost tours in Ireland, with several operators running evening walks through the medieval city that take in the castle, the cathedral and the city's long and occasionally dark history. The medieval streetscape of Kilkenny is genuinely atmospheric after dark, and the tours are well researched and entertaining.

Dublin has a wide range of ghost tours operating throughout October, covering everything from the city's Viking history to its Georgian past and its literary connections. Tours of Glasnevin Cemetery are particularly popular at Halloween and offer a genuinely interesting perspective on Irish history alongside the spooky atmosphere.

Cork and Waterford both have ghost tour operators who run special Halloween programming, and the historic centres of both cities provide excellent backdrops.

Pumpkin Patches

If you are travelling with children, or simply enjoy the ritual of picking your own pumpkin, Ireland has a growing number of excellent pumpkin patches operating throughout October.

For visitors in the west of Ireland, our guide to pumpkin patches in the West of Ireland covers the best options in Galway, Mayo and the surrounding counties.

For those based in or visiting the capital, our Dublin pumpkin patches guide has everything you need to know about the best farms and pick-your-own experiences within reach of the city.

Most pumpkin patches operate throughout October and into early November, with the busiest period falling in the two weeks before Halloween.

OPW Free Wednesdays — Heritage Sites

October is one of the best months to visit Ireland's historic sites, and the OPW's free admission on the first Wednesday of every month means you can explore some of the country's most significant heritage sites without paying entry fees.

Sites like Trim Castle, Kilkenny Castle, Rock of Cashel, Glendalough and dozens of others are included in the scheme. Visiting a medieval castle or ancient monastic site in the atmospheric light of an October afternoon is a genuinely memorable experience.

For the full list of participating sites and everything you need to know about the scheme, read our OPW Free Wednesdays guide.

Planning Your Halloween Trip to Ireland

A few practical notes for anyone planning a Halloween trip to Ireland:

Book accommodation early. The major festival weekends — particularly Derry Halloween and Púca Festival — fill up quickly. If you are planning to attend either event, booking your accommodation several months in advance is strongly advisable. Our accommodation guide has options across the country.

Dress for the weather. Late October in Ireland can be mild, but it can also be wet and cold. Layers, a waterproof jacket and comfortable shoes are essential for outdoor events.

Check event websites for updates. Festival programmes are typically confirmed in the weeks leading up to the events, and specific dates and ticketing details can change. Always check the official event websites before travelling.

Combine events with wider exploration. The regions hosting the major Halloween events — Meath, Derry, Galway, Dublin — all have excellent things to see and do beyond the festivals themselves. Our destinations guide has ideas for extending your trip.

Halloween in Ireland is not just a single night. It is a season — and one of the best times of year to experience the country at its most atmospheric.
