The three Diggerlands - Strood in Kent, Langley Park in Co. Durham, and Cullompton, Devon - are designed for children to indulge their muddiest Bob-the-Builder fantasies. Like a theme park with added grit, they are full of diggers, dump trucks and assorted machines with hydraulic scoops, cranes, lifts and shovels. They feature lots of mud, big tyres, frantic lever twiddling, and children screaming with terror or triumph. The action spreads from the shed-like café and shop across big, safe fields, man-made ponds, off-road tracks and muddy digging areas. Take wellies.
Something for children?
A dream-come-true chance to dig a hole in a muddy field with a JCB, take scary rides in a digger's shovel, drive a dumper truck, ride pedal-powered diggers, and enjoy gentle trips on a "digger train". They can also try Land-Rover safaris, all-terrain-vehicle rides, a soft-play centre, a large adventure playground, a bouncy castle, a sandpit and, indoors, PlayStations. Trained digger experts are on hand to help, and exploits can be tailored to age, ability and courage.
Something for adults?
All these fun activities can be safely performed under the pretext of accompanying your children. Also, adults-only JCB racing events are regularly arranged (call to check), and dump truck races for adults are held on the last Friday of the month, March to November, from 6.30pm. Drivers pay £25 each, spectators £10, children £5, including food and drink. Other events include: bring-your-own-off-roader days, dancing diggers' stunt display team, Bob-the-Builder fancy dress days, and young driver tuition.
The Dig Inn supplies decent fast food, but accepts cash only. Meals cost £4 for adults, £3 for children, and the authentic builders' menu includes burger and chips, fishfingers and chips, and curry and chips. Tea and coffee is £1. There's a picnic area and a Snack Shack.
The Goodie Store of Diggerland, with branded clothes, Bob-the-Builder toys, JCB souvenirs and model diggers by Lego, is easily the most dangerous section of the park for adults with children.Must-have treats range from a child-sized Diggerwear T-shirt (£4.95) to the JCB Chief Mechanic Set (£11.99).
