Festivals and holidays in Wales
Ranging from the epic to the absurd, Wales’ wealth of festivals sees all walks of life partying in muddy fields across the country. Many of the events on the nation’s annual calendar are uniquely Welsh with an ancient pedigree, notably eisteddfodau – age-old competitions in poetry and music – that still form the backbone of national culture.
Many towns and cities now have annual arts festivals of some kind, mentioned throughout the Guide and, in the case of the major events, in the list below. There are numerous other events with a distinctly surreal edge – from the Cilgerran coracle races to bizarre happenings like peat-bog snorkelling competitions and parading around Llangynwyd village with a horse’s skull to welcome in the new year (the Mari Lwyd).
Rock festivals, DJ-led events and New Age fairs and festivals are another common feature of summer throughout Wales; these are usually publicized by handbills, posters in wholefood shops and cafés, and by word of mouth.
