The best big indoor attractions for rainy day activities Cornwall loves

When the forecast is set in for the day, head for one of Cornwall's showpiece indoor attractions. These are the reliable, all-weather choices that easily fill a morning or a full day, and they top most lists of rainy day activities Cornwall visitors return for.

The Eden Project (about 30–40 minutes)

The Eden Project is arguably the ultimate wet-weather day out. Its two enormous biomes — one steamy rainforest, one Mediterranean — keep you under cover while you wander through thousands of plants from around the world. There are indoor exhibits, art installations, places to eat and plenty for children to explore, so the rain outside becomes part of the adventure rather than a problem.

  • Mostly indoors, with the biomes offering full cover
  • Great for families, couples and garden lovers alike
  • Allow at least half a day; a full day is easily done
  • Do check the official website for opening times, tickets and any pre-booking

The Lost Gardens of Heligan (about 10 minutes)

Heligan is one of our nearest treasures and, remarkably, it's still magical in the drizzle. The woodland walks and jungle valley take on a hushed, atmospheric quality when it's wet, ferns glisten and there's a good amount of tree cover along the paths. Bring a waterproof and sturdy footwear and you'll have much of it to yourselves. For a fuller picture, read our guide to the Lost Gardens of Heligan before you go.

  • Woodland and jungle areas offer partial cover
  • Only around ten minutes from Gorran Haven
  • Indoor tea room for warming up (check current opening)
  • Best enjoyed with proper waterproofs

Charlestown and the Shipwreck Treasure Museum (about 20 minutes)

The historic port of Charlestown is a film-set of a harbour, often lined with tall ships. The Shipwreck Treasure Museum takes you underground through tunnels and galleries packed with salvaged artefacts — a genuinely absorbing hour or two out of the weather. Pair it with a hot drink overlooking the harbour when there's a lull in the rain.

Mevagissey Aquarium and Museum (about 10 minutes)

Just along the coast, the pretty fishing village of Mevagissey is a joy on a wet day. The small aquarium showcases local sea life, while the village museum tells the story of Cornish fishing in a characterful old building on the quay. Add in the World of Model Railway and you've an easy afternoon of indoor pottering. Our Mevagissey day trip guide has more ideas for the village.

  • The World of Model Railway — a delight for children and enthusiasts
  • Independent shops and galleries to duck into between showers
  • Cafés and pubs for a warming lunch
  • All within a short drive of the house

National Trust houses and gardens

The National Trust is a wet-weather hero in Cornwall. Grand houses such as Lanhydrock come into their own on a rainy day, with room after room to explore under cover, while gardens like Trelissick and the seasonal Caerhays Castle gardens are atmospheric in soft rain. Do check seasonal opening before setting off, as some properties and gardens open only at certain times of year.

A cosy day in at The Beach House

  • Dig into the bookcase — perfect for a slow read with a hot drink.
