Who can participate in an Overnight?
Children ages 6-12 and adult chaperones. We ask that the ratio of adults be at least 1 adult for every 10 children with a minimum of two adults regardless of group size. This is a great opportunity for a special class field trip or a scout group outing. Overnight events are not available for groups of adults.

Don’t have a large group? Email for more information about our individual registration overnights available for Tiger, Cub and Webelos Scouts!
