The Norwich Science festival has a different theme each day (nature, climate change, the human body and so on) and lots of child-friendly workshops – including one called The Science of Poo. The festival is based at the Forum but has events across the city and online (23-30 Oct, some free events). At Gilbert White’s House in Selborne, Hampshire, children can make eight-legged friends on a spider safari (£5, 28 Oct).

Fairytale Farm, an Oxfordshire attraction where disabled children come first (but all are welcome), is holding Illuminated Evenings every weekend until the end of November (from £6.75pp including supper, until 28 Nov).

Halloween

With Halloween falling on the final day, half-term has a spooky feel this year.

Heritage railways are hosting themed journeys, such as Wizard Week and Fright Nights on the Isle of Wight Steam Railway, featuring witches, magicians, owls and a journey through haunted woodland (£14.50 adults, £7.25 children, 25-31 Oct).

Outdoor Arts

Winter Droving, usually a one-day festival in Penrith, Cumbria, is expanding to three days this year. As well as lots of live music (including the UK’s only all-female mariachi band), the programme includes circus performers, a vintage funfair, an arts and crafts market, a children’s trail, and food and drink in the market square (£2, 28-30 Oct). Lincoln’s digital culture festival, Frequency, is celebrating its 10th anniversary, with outdoor installations, performances and exhibitions. Highlights include Luma, a giant inflatable robot snail; the Invisible Man, a puppet-cum-audiovisual projection; and Monolith, “an audio adventure into eternity” (free, 28-31 Oct). Little Amal, a 3.5m-tall puppet child refugee, has walked 8,000km across Europe, meeting real child refugees along the way. She has landed in the UK for the final part of her journey and over half-term will attend outdoor events in London, Oxford, Coventry, Birmingham, Sheffield and Barnsley, before arriving in Manchester on 3 November (free).

Indoor Arts

Chester, Designed by Nature is a new six-month community arts project. The first part, open in time for half-term, is the Nest: an enchanted forest hosting performances, art workshops such as shadow puppetry and activities including mindfulness for children (some free events, 23 Oct to late Nov). The Box in Plymouth is hosting the biggest exhibition of Indigenous Australian art outside Australia. Songlines: Tracking the Seven Sisters showcases the work of more than 100 artists, across paintings, photographs, objects, song, dance and multimedia (£10, until the end of February). Margate’s new Crab Museum is opening for a period of public testing, inviting visitors to give their feedback on Europe’s only museum devoted to the decapod. Exhibits cover everything from history and philosophy to the climate crisis, the forgotten story of the giant Margate crab and jokes about woodlice (free, booking required, 23-31 Oct).

Activities

The Woodmill Outdoor Activities Centre in Southampton runs 90-minute discovery sessions to introduce people to new sports. Over half-term, families can try archery or climbing, or children can take part in a full multi-activity day (90 minutes £22 adults, £12 children, £37 full day). Harry Potter: A Forbidden Forest Experience is a magical new woodland trail at Arley Hall & Gardens in Northwich, Cheshire. Visitors will come face to face with creatures from the Harry Potter books and Fantastic Beasts film – hippogriffs, centaurs, unicorns, nifflers and more – and can cast spells with their wands, including conjuring a patronus charm (from £19, tickets selling fast, until early 2022). Lord of the Rings fans may prefer Ring Quest at West Stow Anglo-Saxon village and country park, a treasure hunt to find rings and runes and save Middle Earth. Children can visit a Hobbit Hole, face dragons and giant spiders, meet Halbarad, the Ranger of the North, and have a go at archery (£6 adults, £4 children, plus £2 for each Ring Quest pack, 23-31 Oct).
