You can find the link to the Jamboree Passport here.
Scouts will be given a passport on arrival at the Jamboree and need to take it everywhere with them.
The passport is stamped at different locations and if all requirements are met each Scouts earns the Jamboree "award" at the end of the Jamboree. Usually the award consists of some sort of gift.
The more activities your patrol does the more they will get out of their Jamboree experience.
