Every October, pumpkins appear in shop windows, haunted attractions open their doors and cities prepare for costume parades. For many travellers, Halloween is an opportunity for a themed holiday. For destinations, it is also a way to attract visitors outside the traditional summer travel season.
Yet Halloween's origins lie far from the commercial celebrations associated with the United States today.
From Samhain to trick-or-treating
Halloween can trace its roots to Samhain, an ancient Celtic festival marking the end of the harvest and the beginning of winter. Celebrated in Ireland and other Celtic regions more than 2,000 years ago, Samhain was associated with the changing seasons and beliefs about the relationship between the living and the dead.
Communities lit bonfires and wore disguises, while seasonal traditions developed around remembering the dead and protecting households from spirits. Over time, these customs blended with Christian observances, including All Saints' Day on 1 November and All Souls' Day on 2 November. The evening before All Saints' Day became known as All Hallows' Eve, eventually shortened to Halloween.
The history is not a simple, uninterrupted progression from one ancient festival to today's celebrations. Halloween developed through centuries of religious, cultural and social change.
Irish and Scottish emigrants carried traditions to North America during the 19th century, where they evolved into familiar customs such as pumpkin carving, costume parties and trick-or-treating. By the 20th century, Halloween had become an established part of American popular culture.
The Smithsonian Magazine's history of trick-or-treating traces how older European customs developed into the modern American tradition, which became particularly popular after the Second World War.
Today, Halloween is celebrated in many countries, although its popularity and traditions vary considerably by market.
Ireland turns heritage into a tourism proposition
For Ireland, Halloween offers an opportunity to connect international visitors with the country's cultural heritage.
The tourism campaign Ireland: Home of Halloween promotes the island as the place to experience the festival's historical roots, using folklore, landscapes and contemporary celebrations to encourage autumn travel.
The strategy has measurable economic ambitions. According to Fáilte Ireland's 2026 programme announcement, the island's Home of Halloween programme supported more than 830 events in 2025, attracting over 322,000 domestic and international visitors and generating an estimated €43 million in economic impact.
This year's programme includes the Púca Festival and Derry Halloween, alongside events across participating destinations.
In Northern Ireland, Derry Halloween marks its 40th anniversary in 2026. Running from 28 October to 1 November, the festival features parades, performances, folklore-inspired experiences and fireworks. Organisers expect more than 120,000 visitors, according to Tourism Ireland.
The events demonstrate how a cultural tradition can support local tourism businesses while giving visitors reasons to explore destinations beyond their best-known attractions.
The American model: entertainment and experiences
In the United States, Halloween tourism has developed along a different path, combining community traditions with commercial entertainment.

New York's Village Halloween Parade attracts spectators and participants with elaborate costumes, puppets and street performances. In Orlando, Universal's Halloween Horror Nights turns horror films and special effects into ticketed attractions. Historic Salem, Massachusetts, draws visitors with witch-trial history, guided tours and month-long seasonal events.
These experiences appeal to different audiences, from families seeking autumn activities to adults looking for horror-themed entertainment.
For tourism businesses, the commercial opportunity extends beyond admission tickets. Visitors may book hotels, dine locally, shop and combine events with other attractions. Events lasting several weeks can also spread demand beyond Halloween night, although the economic impact varies by destination.
The model shows how destinations can turn a familiar celebration into a reason to travel, rather than relying solely on traditional sightseeing.
What Halloween means for global tourism
Halloween's international reach creates three broader opportunities for the travel industry.
First, it can help extend the tourism season. Festivals and seasonal attractions give destinations reasons to promote autumn visits, potentially supporting accommodation providers, restaurants and local businesses during periods outside peak summer demand.
Second, it creates opportunities for cultural tourism. Ireland can promote Samhain and its folklore, while American destinations draw on neighbourhood traditions, entertainment and popular culture. The strongest propositions connect events with local history and experiences that visitors cannot easily replicate elsewhere.
Third, it supports experience-led travel. Travellers can plan trips around parades, immersive attractions, historic sites and seasonal food. Tour operators can incorporate these activities into short breaks or longer itineraries, particularly when events encourage overnight stays.
However, Halloween is not universally celebrated in the same way, and destinations should avoid treating different cultural traditions as interchangeable.
Mexico's Día de los Muertos, or Day of the Dead, for example, is a distinct tradition centred on remembering and honouring deceased loved ones. Although it takes place around the same period, its customs and cultural significance differ from Halloween. Tourism promotion needs to reflect those differences respectfully.
Beyond the scares
Halloween's journey from an ancient seasonal festival to an international commercial celebration illustrates how cultural heritage can create tourism opportunities when combined with events, storytelling and visitor experiences.
Ireland is using its historical connection to attract autumn travellers, while the United States continues to build on Halloween's popularity through entertainment and community celebrations. Other destinations can also develop seasonal experiences around their own traditions, provided these are presented accurately and with local communities involved.
For the global travel industry, the lesson is that a festival need not be a national holiday to influence travel decisions. With thoughtful programming and effective promotion, a few weeks of seasonal activity can give visitors another reason to explore a destination — and give local businesses an opportunity to benefit.
Halloween may have begun with ancient beliefs about the changing seasons, but its modern tourism significance lies in how destinations connect history, culture and experiences to encourage people to travel.
