Ireland's reputation as the home of Halloween lies in Samhain, the ancient Celtic festival marking the the end of the harvest and ushering in winter. This year, you can embrace the darkness with a bit of light at Samhain Fire and Shadows Processions taking place across the country over the October Bank Holiday weekend.

Ireland's oldest city will see the first event on October 25 – the Samhain Shadows and Fire Procession in Waterford is inspired by An Dearg Dua, a mythical vampire from Waterford's Iron Age. The next will wind through Limerick on October 26 as part of the wider Samhain: Limerick's Hallowe'en Festival and invoke the spirits of the Shannon. Close out the weekend with the final procession at the Dead of Night Halloween Festival in Longford on October 28, with a fiery finale in Connolly Barracks.

Best for: Adults and families. Free.
