SAGGA was formed on 21 April 1957, and was originally nicknamed the "Peter Pan Club".

This framework lets them choose what to do: building up skills and experiences, trying something new, joining activities such as camping, winter walking, sailing and crafts.

Their only criteria for membership are sympathy with their aims, and undertaking a CRB check.

SAGGA decided to revisit its roots with the GaSCiT events of 2000 and 2003, and while they brought together members of both halves of the Scout and Guide Movement, the aim this time was to support and train leaders lacking in the skills needed to organise their own camps.

SAGGA continues to run major projects to support the Scout and Guide movement.
