A light source for the evening is a must! There are many kinds of battery-operated lanterns available, which are safer and more convenient than fuel-based lanterns. LED lights are high-intensity, have a long battery life and are lightweight. Headlamps are a great hands-free option. Remember to use environmentally-friendly rechargeable batteries when possible.
Duct tape is an essential camping tool. It can be used to temporarily repair a tent pole, patch a hole in a canoe, and much more.
Rope and bungee cords can be used to fix tent ties, create a clothesline, put up a tarp and much more.
A sewing kit can be used to repair your sleeping bag, rips in clothing or other personal items. If you get a hole in your tent, do not sew it- patch it with duct tape or a tent repair patch- a stitch creates a water entry point.
A hatchet for chopping kindling into finer pieces is handy.
A screwdriver or multi-tool may come in handy for quick repair jobs.
