Short answer: Eden is the family day and the cheaper evening: lights from 20 November (£12.50 per adult, under-16s free), Father Christmas from 21 November, and the ice rink from 17 October. Heligan's Night Garden is the magical one: selected nights 13 November to 2 January, adults £23.60, children £14.20. Both sell out on December weekends.

Eden Project runs Christmas from mid-November to early January: an ice rink beside the biomes (skate hire included with a session, penguin aids for small ones), Father Christmas in his grotto as a separate booked experience with a gift, festive planting and lights inside the Mediterranean biome, and the usual play and café. The rink is the thing children remember. Annual passholders get in free but still pay for skating and Santa; day tickets are pricey, so it's a better day for members or people who'll come back.
2026 dates: confirmed. Evening lights on selected nights 20 November to 2 January (4pm–8:30pm, Lights Pass £12.50 per adult, under-16s free); Father Christmas £16 per person plus admission; ice rink 17 October to 21 February. Full details: Christmas at Eden 2026 and Eden ice rink prices.
The Lost Gardens of Heligan turns into a light trail after dark on selected nights: lanterns through the jungle, illuminated walks, fire pits, hot food and drink. It's an evening rather than a day — an hour and a half at a slow pace — and it's beautiful in a way Eden's isn't. It's also cold, muddy in parts and not ideal for pushchairs (a carrier is easier). Timed tickets, and weekends go first.
2026 dates: confirmed. Selected nights 13 November to 2 January, entry from 4:15pm; adults £23.60, children (3–16) £14.20, under-3s free. Every date: Heligan Night Garden 2026.
The Charlestown Beach Boxing Day swim, run by the rowing club, registers from 10:45 for an 11:30 dip and — unusually — allows wetsuits. Pebbly beach, so wear something on your feet. The harbour pubs are open after.
Eden's car parks are big and free with the ticket; Heligan's is fine outside peak nights. Neither is reachable in the evening by public transport — it's a car job. Dogs: welcome on short leads at Heligan's Night Garden; for Eden's rules see dogs at Eden.
Getting to Heligan: walk, cycle or bus from Mevagissey.
