Half-term washout?

October 29, 2026 |

Pop over to your local museum or gallery to celebrate Welsh Museums Festival for greener hwyl!

After a wet and windy start to half term, families are being invited to discover their local museum, where many are celebrating Calan Gaeaf, the Welsh Halloween, in ways that are kinder to the planet.

More than 60 museums and galleries are taking part in this year’s Welsh Museums Festival, which runs until Sunday 1 November. This year, the festival has encouraged participating museums and galleries to develop more sustainable activities and events. From nature trails that celebrate the autumn season to crafts made from seeds, scrap fabric and recycled materials, there are plenty of ways to enjoy Calan Gaeaf that are kinder to the planet.

Dr Ken Griffin, President of Museums Federation Cymru, which organises the festival, said: “It’s been lovely to see so many trying new ideas, from willow lanterns to bat boxes. Above all, it’s the perfect time to discover your local museum.”

Heledd Fychan, Cabinet Minister for Culture and Sport, has welcomed “the Festival’s approach to celebrating Halloween in a greener and more sustainable way.”

The festival’s free bilingual Halloween resource, available at most of the participating museums and galleries, points out that around seven million Halloween costumes are thrown away in the UK every year, the equivalent of every person in Wales binning more than two. Its tips for families include:

  • Wear a greener costume. Make a spooky mummy from old fabric, or a witch’s cat from black clothes and homemade ears. You could also find a pre-loved costume and pass it on afterwards.
  • Drop the glitter. Glitter is made from tiny pieces of plastic that can wash into rivers and seas. Decorate with dried flowers, seeds and leaves instead, or make your own sparkle with sand, sea salt or sugar and food colouring.
  • Eat your pumpkin. Don’t bin the inside of your carved pumpkin. Turn the flesh into soup, or roast the seeds for a crunchy snack.
