This is Cornwall's real-life secret garden. Formerly the family estate of the Tremaynes, Heligan's magnificent 19th-century gardens fell into disrepair following WWI, but have been splendidly restored by the brains behind the Eden Project, Tim Smit, and a huge army of gardeners and volunteers. It's a horticultural wonderland: you'll encounter formal lawns, working kitchen gardens, fruit-filled greenhouses, a secret grotto and a 25m-high rhododendron, plus a lost-world Jungle Valley of ferns, palms and tropical blooms. Check whether you need to pre-book a timed entry ticket.
It's also dotted with artworks – look out for the famous sleeping woman, made out of earth and grass – and is a haven for wildlife. If you're lucky you might spot a kingfisher or even an elusive barn owl.
Dogs are welcome but must be kept on a lead at all times.
Heligan is 7 miles from St Austell. Transport for Cornwall (www.transportforcornwall.co.uk) bus 23 links Heligan with St Austell train station (30 minutes, three daily Monday to Saturday).
