Many of the badges available are activity badges, which allow Cub Scouts to show their progress in existing pursuits, but also to try all kinds of new things and form new interests.
Gaining a challenge badge involves accomplishing a number of more ambitious tasks within the Pack or community. There are several challenge badges across a number of themes, from the physical and outdoorsy to challenges dealing with the local community or issues connected with the Scouting world.
In addition, there are a number of special badges, obtained upon joining or moving on from the Pack, or for time spent in the Scouting movement.
Some activity badges are sponsored by outside companies, and these companies often provide extra exciting resource packs to help Cub Scouts towards gaining their badges.
