Grasmere Sports, Cumbria
If the prospect of roller coasters or new-fangled activities (canyoning, anyone?) leaves you cold, introduce the family to some more traditional fun. Among the events on offer at the 161-year-old Grasmere games are wrestling, sheep dog displays and a family tug of war. Proper, wholesome fun! There's also a beer tent, so dads can drink a manly pint of ale while watching the terrier dog show.

Time Travellers Go … Gruesome, Salisbury
Disease, hideous punishments, nasty surgery – a good dose of ghoulishness awaits visitors to Old Wardour Castle in Wiltshire, a 14th-century luxury country pad.
