Short answer: Open: the beaches, the coast path, most town pubs at lunchtime, Eden (usually), Heligan's Night Garden (selected nights), the Boxing Day swims. Closed: the National Trust houses, Tintagel Castle, the Mount, most cafés, all the seasonal attractions. Check social media on the day for hours; websites don't get updated over Christmas.

The honest picture of Boxing Day in Cornwall: it's a beach-and-pub day. A few big attractions open, a few cafés in the year-round towns keep going, and nearly everything else is shut. Here's the usual pattern — always confirmed on the day by the venue's social media, never by its website.
These have opened on Boxing Day in previous years and usually do lunch; book, because they're the only ones and everyone knows it.
Ring or message the day before. Boxing Day hours change on a whim, kitchens close at 3pm, and the website will still say "open daily".
