A good camp looks effortless from the outside. It is the result of a great deal of planning that nobody is supposed to notice.
Most of what makes an outdoor week succeed is decided before anyone arrives: how far the walks are, what happens when it rains, who is responsible for what, and whether the evenings give a group somewhere to settle after a long day.
These notes are written for the people doing that planning — volunteers, teachers and small organisations running programmes without a professional operations team behind them.
The planning rule that saves the most trouble: design for the tired child on day four in the rain, not for the enthusiastic one on day one in the sun. The programme that works for the first works for both.
Trails covers route planning and pacing for mixed-ability groups. Water is about activities on and near water, where the margin for improvisation is smallest. Evenings deals with the part of the day that decides whether a group becomes a group.
None of this replaces proper qualification or local regulation. It is the planning layer that sits on top of both.
