Bear Grylls and David Walliams visit Pencarrow Scout Jamboree
Survival expert Bear Grylls and comedian David Walliams have dropped in on the final day of the Scouting Jamboree in Cornwall.
About 1,500 scouts from around the world have spent the week at Pencarrow, near Bodmin.
Grylls, who is chief scout in the UK, said he wanted to show Walliams the "amazing" things scouts do, as he bids to encourage more adult volunteers.
After being flown in by helicopter, the pair got involved in activities.
The trip was part of Grylls's plan to visit the whole of the UK during his time as chief scout.
He has already visited the north and south of England, the Midlands and Wales and later on Saturday will fly to the Kent Jamboree, Campdowne International Camp and the Jamboree Camp at the South of England Show Ground.
The Scout Association has a membership of almost 540,000, but it has a waiting list of nearly 38,000, which is why more adult volunteers are needed. In Cornwall, the waiting list is currently about 500.
"Scouting gets adults and young people outdoors and active," Grylls said.
"It boosts your confidence, and teaches life skills that are hard to find elsewhere - that's why scouting is more popular than ever."
The Kernow International Jamboree, which has included scouts from Hong Kong and Ghana, has involved a range of activities such as bushcraft skills, canoeing and sailing.
"It's great to see Bear calling on more people to volunteer for the scouts - it's such a brilliant thing to do," said Debby Davison, a scout leader from Boscastle.
Salli Bartlett, one of the organisers in Cornwall, said the visit by Grylls and Walliams was a fitting end to a successful week-long jamboree.
"The kids have had a ball. They've made new friends and learnt new skills, so it's been an absolutely fantastic success."
