Short answer: Truro in half-term week: do the outdoor banker in the morning, keep the indoor fallback ready, and check winter opening hours before driving anywhere. Half term runs 26–30 October for most schools.
Truro is the half-term insurance policy: the flattest, most indoor-rich day in Cornwall, for whichever day the weather writes off entirely.
The dates: half term for most Cornish schools is Monday 26 to Friday 30 October 2026 (a few academy trusts take the week before as well), and most English counties share the same week — so expect other families about, but nothing remotely like summer.
Have the wet plan ready before you need it — the rainy-day guide is the one to bookmark, and breakfast on the flat covers the refuelling.
Late October here means real weather and shorter days — plan the outdoor thing for the morning, keep the indoor thing in your back pocket, and check opening hours before driving anywhere: this is the week many places switch to winter hours, and a few close mid-week. Sunset is around 5pm, which is not a problem if you know it and a mutiny if you don't. Plenty of attractions run Halloween events through the week — check their own pages nearer the time.
Everything else — filtered by who's with you — is in the Truro guide, and the county-wide Bonfire Night guide covers what the week rolls into next.
