Free Events in Wales

Many of the best events in Wales are free to attend. St David’s Day parades, most of the Eisteddfod’s Maes activities, outdoor music performances, Cadw open days (offering free castle entry several times a year), parkrun events in scenic locations, and community food markets across the country cost nothing. The National Museum Cardiff, St Fagans and the National Waterfront Museum in Swansea run free exhibitions and events year-round.

Practical Tips for Attending Welsh Events

Book accommodation early.

Festivals like Green Man, the Eisteddfod and the Royal Welsh Show fill up accommodation across the surrounding area weeks or months in advance. Holiday cottages within 30 minutes of major events are the first to go.

Check transport options.

Many festivals run shuttle buses from nearby towns and train stations. Cardiff events are well served by public transport, but rural festivals in the Brecon Beacons or Mid Wales are best reached by car. Our itinerary planning guide covers transport in detail.

Prepare for Welsh weather.

Even summer festivals can have rain. Waterproofs and layers are essential for any outdoor event in Wales, whatever the forecast says.
