Newsround sent Adam to check out the 21st World Scout Jamboree, held in the UK.
The jamboree goes on for 12 days and there is loads to do, so Adam needs a Scout-mobile to get around.
Around 40,000 scouts are at the jamboree and they all need places to stay, so there are loads of different tents.
And there are lots of things to do too, with these Scouts trying out some drumming.
Coyle, 9, said: "The best thing about being in Scouts is that you get to play lots of games."
Shakira, 10, said: "You get to go loads of camps and spend nights with all your friends."
Owen, 9, said: "You get to swap your badges for other people's badges and meet other people from different countries."
There was so much happening at the giant campsite that Adam got a bit lost in his Scout-mobile.
And he also had a go on this wooden big wheel. Don't look down, Adam!
