Every camping trip is different - different locations, different activities, and different weather. Below are some packing lists for typical Scout trips:
New Scout Campout: a one-night campout each Spring in Lexington (Willard's Woods) - New Scout Campout Packing List
Overnight Camping: a one-night campout or long hike - Overnight Camping Packing List
Backpacking: a two- or three-day backpacking trip requires self-sufficiency, without over packing - Backpacking List
Cold Weather Camping: special attention is needed for cold weather camping. The coldest of Troop 160's winter campouts is the annual "Deep Freeze" where the Scouts sleep in snow quinzees - Deep Freeze Packing List
The Camp Bell Cookbook is a useful source of ideas for any campout.
