What to do on a rainy day in Cornwall
Date published: 09 Apr 2025
It’s typical, isn’t it? You plan yourself a nice break in a beautiful cottage, make sure it’s dog-friendly so the pooch(es) can come, make sure the time off work is all sorted – and then the forecast comes in. All that sunshine of the past three weeks has fizzled, and the clouds have gathered.
Ah, the quintessential Cornish weather. It’s beautiful when the sun’s out, but when it’s raining? Well, that's a bit of a different story. But fret not - rainy days don’t mean your Cornwall adventures with your dog have to be put on hold.
From fascinating museums to historic sites, there are plenty of indoor (and mostly dry) activities to enjoy with your four-legged friend in tow. Cornwall loves dogs, so you won’t have to worry about filling your time.
1. Pendennis Castle, Falmouth
Set on a cliff with views that’ll take your breath away, Pendennis Castle isn’t just any old historic site - it’s one of Cornwall’s most impressive landmarks. Built by Henry VIII to defend the Fal Estuary, this castle offers a proper adventure for you and your dog, with plenty to explore from the impressive keep to the scenic grounds. And don’t worry about the rain - pop into the cosy tea room or take shelter in the castle’s nooks and crannies while your dog enjoys the sights.
2. Bodmin and Wenford Steam Railway, Bodmin
Hop aboard a vintage steam train with your dog and embark on a charming journey through the Cornish countryside. The Bodmin and Wenford Railway offers a scenic 13-mile return trip, and dogs are allowed on board - although they’ll need to stay off the seats and on a lead (no cheeky paws on the table!). It’s the perfect way to enjoy the outdoors from the comfort of an old-fashioned carriage, without getting drenched.
3. Wheal Martyn, Near St Austell
Ever wondered where that glossy magazine you’re reading gets its shine? Cornwall's historic China Clay industry is responsible for much of it, and you can learn all about it at Wheal Martyn. This fascinating museum and country park lets you discover the incredible history behind this natural resource, and best of all, your dog can join in the exploration - on leads, of course. Wander around the outdoor exhibits, or check out the indoor displays if it’s really coming down.
4. Newlyn Art Gallery & The Exchange, Penzance
If you're looking for something a bit more refined, Newlyn Art Gallery and its sister site, The Exchange, are fantastic spots to soak up Cornwall’s thriving arts scene. Both galleries are dog-friendly, so you and your pooch can wander around the exhibits in peace. Whether you're admiring contemporary art or just enjoying the atmosphere, you’ll both feel right at home.
5. Cornwall at War Museum, Davidstow
For something a bit more interactive, head over to the Cornwall at War Museum. Housed at the historic Davidstow airfield, this museum offers an immersive experience into the region’s WWII history. Dogs are welcome throughout the museum, so feel free to bring your canine companion along as you explore exhibits on wartime aviation and local history. If the rain’s lighter, you can even enjoy a brief stroll around the airfield, too.
6. Healeys Cyder Farm, Near Newquay
What better way to brighten up a rainy day than with a visit to a working cyder farm? Healeys Cyder Farm, just a short drive from Newquay, is the perfect place to taste some local cider (for the humans, of course) while your dog enjoys the fresh farm air. They’re dog-friendly and your pooch will love the bustling atmosphere. Learn about the cider-making process and sample some of the finest ciders Cornwall has to offer. There are just a couple of areas that are off-limits to dogs, but you can still enjoy most of the attraction, including the restaurant.
7. Museum of Cornish Life, Helston
Located in the heart of Helston, this charming museum is packed with fascinating collections about Cornwall’s past. From archaeology to social history, you’ll find something for everyone - and your dog can tag along! Take a look at everything from toys and old gardening tools to a collection of historic costumes. A great way to spend a rainy day, and a perfect chance to get cosy while learning something new.
8. St Mawes Castle, Near Truro
Another of Henry VIII’s coastal fortresses, St Mawes Castle is one of the most well-preserved examples of his military architecture. Dogs are welcome here too, so you and your furry friend can enjoy the magnificent keep, explore the grounds, and take in the stunning views of the Carrick Roads. If the rain’s really coming down, you can always pop into the gift shop or listen to the informative audio tour while staying dry inside.
9. The Lost Gardens of Heligan, Near Mevagissey
If you and your dog don’t mind a bit of rain, the Lost Gardens of Heligan are worth a visit. Though it’s primarily an outdoor experience, there’s plenty to see under cover, from the magnificent Jungle to the ancient woodlands. Dogs are welcome throughout the garden, so you can explore at your own pace and enjoy a peaceful walk - just be prepared for a splash or two.
10. Visit a dog-friendly pub
Plenty of Cornwall's pubs welcome pups with open paws, so you can enjoy a cosy drink with your dog by your side after a day of exploring. Whether you’re looking for a traditional Cornish pub with a log fire or a quirky seaside spot, you’ll find plenty of options that welcome your four-legged friend. Just make sure to check in advance, as some places may have specific rules or busy times where dogs might be restricted.
