Autumn is spectacular at West Dean Gardens. Wander around walled fruit orchards, an Edwardian pergola and arboretum, or duck into one of the Victorian glasshouses. Foodies should hit up the café for hearty dishes made from home-grown veg. Menus change according to the seasons, but expect artisan charcuterie and Sussex cheese sharing boards all year round. Pre-book tickets before you visit.
Get there: one hour 30 minutes by train from London Victoria to Chichester, then 20 minutes by bus.
