Chief Scout Bear Grylls has launched a "Summer Manifesto" for children.
The adventurer's to-do list for youngsters includes getting fit and doing something to help others.
"The summer holidays are a massive opportunity for fun, challenge and adventure," he said. "It's a time when kids can get outdoors, build dens, learn skills, make friends and have the freedom to discover who they are."
