I do all kinds of camping, from backpacking to staying in my camping tent trailer or my friend’s camper. Both are fun and have their various advantages. By far, the biggest advantage to backpacking, IMO, is that you can get to locations most people won’t or can’t get to. It took a few trips to figure out what to bring and what not to bring as weight is a main issue with backpacking. Here’s a few suggestions for backpacking:
I try to backpack near mountain creeks or rivers, so I have a water supply. If you are in this scenario, bring a nalgene or similar tough water bottle and a good water filter. Nothing beats taking a “pit stop” and filtering and drinking fresh cool mountain stream water. And a filter is much lighter than trying to pack enough water.
Bring light food. Canned food is heavy and should be avoided if you can. Dried food, MREs, and similar things are pretty light weight. Bring a small backpacking stove to do any cooking. Bring some snacks to munch on while you are hiking like some granola bars or something that doesn’t need refigeration.
Bring a sleeping bag that is appropriate for the temperature. Nothing is worse than shivering all night because your bag isn’t warm enough.
Bring a small and light sleeping mat. You will need this layer for comfort as well as insulating your body against the ground.
Bring a good hatchet and good knife and have a friend bring an army shovel. You may need to dig a hole, chop down a small tree, or cut a stick for roasting marshmallows.
Bring toilet paper or paper towl. It’s not fun to wipe your ass with leaves or pine needles.
Bring a small medical kit. Some bandages, band-aids, ibuprofen, etc. Enough to make a splint if someone should roll an ankle or something. You can make a splint from nearby trees and an ace bandage. Mosquito repellent is also important if there will be biting insects.
Pay attention to the weather. If major storms are forcasted, maybe postpone the trip a week. It’s not fun to just sit in rain for a whole weekend.
Go on a shorter trip first, maybe just a one night stay with a fairly short hike in (maybe less than 5 miles). This way if you absolutely have to get back, you can. Do this a few times until you can fine tune what you need to bring and feel comfortable.
That should be enough to get you going. As you can see, it’s not too expensive. I usually bring the above items, and a fishing pole and tackle (we fish a lot while camping). Cost is not too great, as you can get a small backpacking stove for pretty cheap, and sleeping bags aren’t too much either. Just remember when you are shopping that weight matters.
