Expeditions and Hikes
Scouts will get the chance to join an expedition or hike, particularly if they want the chance to attain the Expedition Challenge badge. Challenge Badges are harder to achieve that the activity badges and count twoards a scout's chance at attaining the coveted Gold Scout Award.
Most, or all, of these forms will be needed for an expedition or hike. Note, however, that each expedition or hike is different, and details of what the purpose or challenge of your particular outing should be laid out in a briefing letter from one of the leaders or the expedition organiser.
