It is difficult -- if not impossible -- to create a single gear list that would be applicable to all of your possible camping trips. A gear list depends on many factors: length of trip, type of trip (whitewater canoeing, flatwater canoeing, sea-kayaking, backpacking, snowshoeing, etc.), weather, number of portages, etc.
Below I have created a different list for each of a number of recent camping trips that I have been on. Find one that most closely matches the type of trip you will be going on and then use it as a gear guide adapting as necessary to your unique situation.
