Short answer: Bodmin Jail is the obvious one, and it's also rare in being dog-friendly indoors. Discovering42 is a hands-on science museum that keeps children busy for hours. Both work in any weather.
Bodmin is inland and never depended on beach weather, which makes it a genuinely strong wet-weather option.
An immersive attraction with projections and storytelling rather than just old cells. Around two hours, entirely indoors, and unusually it welcomes dogs throughout — genuinely rare for an indoor attraction.
A hands-on science museum, quirky and interactive, that adults enjoy as much as children. A proper indoor rainy-day destination, and dog-friendly too.
Heritage steam with covered carriages — the journey works fine in rain, which is more than can be said for most Cornish attractions.
The house is indoors and substantial — allow a couple of hours. Dogs aren't allowed inside, though the parkland is dog-friendly.
Flory does genuinely exceptional food that reviewers compare to Michelin-starred places, and The Tavern is a warm Portuguese spot with tapas-style plates.
Bodmin Jail's guided tours cost slightly more than the self-guided option and get booked up — reviewers consistently say the guide is worth it. Worth reserving rather than turning up on a wet day when everyone else has the same idea.
