Webelos dens are for boys who have completed third grade (or reached age 10). The Webelos den program is different from the Cub Scout den program: Instead of being based on a monthly theme, the Webelos den program is based on one of 20 Webelos activity badges.

Webelos Scouts work on activity badge requirements during their weekly den meetings. When they have completed the activity badge requirements, the Webelos den leader, rather than a parent, approves most of the activity badges.

Den meetings also include games, stunts, and preparation for the Webelos den's part in the pack meeting. In addition, Webelos Scouts prepare for overnight camp outs and joint activities with a Boy Scout troop. One of the purposes of the Webelos den is to prepare boys for Boy Scouting and to graduate Webelos Scouts into a Boy Scout troop.
