If you’re planning an October half-term holiday in Cornwall, I’d put Halloweden on your family outing list. The Eden Project’s seasonal celebration returns from 24 October to 1 November 2026, bringing a playful mix of nature, music and Halloween fun.
This year, visitors can explore the Freaky Fungi Trail, discover an immersive UV Glow Room and enjoy live performances from Eden’s resident Halloween band, The Scarecrows. On Saturday 31 October, there’s extra fun in the Mediterranean Biome, with games and treats for visitors arriving in costume.
I like the sound of a Halloween adventure built around nature’s strange little wonders. It’s something different to add between beach walks and cosy evenings back at your holiday cottage.
For guests staying around Hayle and St Ives, Eden is a day trip further afield, so I’d set aside a full day. Halloweden activities are included with admission; ice skating costs extra, and Eden recommends booking your visit ahead.
An autumn stay with Golds Cornish Properties gives you the chance to enjoy Cornwall’s coast and a little seasonal magic.
