Scouting caters for boys from Year 6 up to Year 13. The philosophy of Dulwich Scouting is to encourage boys to take responsibility from a young age while developing a sense of participation and teamwork. Boys are expected to be fully involved and to take the wearing of their uniforms and their scouting promises seriously, but also to have fun and to learn new skills in a positive and supportive environment. The troop is led by Old Alleynians with the support of members of staff. In 2009 Dulwich Scouting celebrated its 80th anniversary.
Scouting provides a wide variety of activities, including personal sporting challenges in the gym, lessons in field-craft and camping skills, and patrol-based enterprises such as engineering, cooking and outdoor wide games. The weekly meetings are supplemented by regular weekends away with many challenging and enjoyable activities such as forestry courses, canoeing, cycling and pot-holing. The main trips consist of camps at Christmas and in the summer holidays which include the whole troop along with hiking and climbing trips to Snowdonia.
For older boys, the Explorer Scouts provide an opportunity to consolidate their knowledge and skills, and to plan and run their own activities. The Explorer Scouts unit meets weekly and has regular trips outside the College in addition to their participation in traditional scouting activities. In recent years the Explorer Scouts have travelled throughout Europe on cultural, hiking and camping expeditions. The Explorer Scouts also provide additional support and expertise for the Troop meetings on a Friday night.
