Camping is most often arranged at the unit level, such as one Scout troop, but there are periodic camps (known in the US as “camporees”) and “jamborees”. Camps occur a few times a year and may involve several groups from a local area or region camping together for a weekend. The events usually have a theme, such as pioneering. World Scout Moots are gatherings, originally for Rover Scouts, but mainly focused on Scout Leaders. Jamborees are large national or international events held every four years, during which thousands of Scouts camp together for one or two weeks. Activities at these events will include games, Scoutcraft competitions, badge, pin or patch trading, aquatics, woodcarving, archery and activities related to the theme of the event.
