What to bring
You really don't need a lot of expensive equipment, but you should carefully select what you bring. Backpacking is generally very safe, but there are hazards. It's very important to be prepared. You also want to be comfortable. Some people love the planning and organization of what to bring. Others hate it. If possible, the person who loves it should be in charge of the checklists.
Besides, you'll have to carry it!
Unless you choose another option (see The Easy Way) you'll have to carry everything you bring. That's why it's called backpacking. This will force you to make packing microdecisions in a way you never could have imagined. As an example, some backpackers break off the handle of a toothbrush in order to save weight. Are you starting to get the idea?
Checklists and maps!
Here are some great checklists and sources for maps:
- REI Gear Checklists
A great variety of checklists are found here.
- USGS Store
The U.S. Geological Survey is the ultimate source for maps. (A good topographical map to take with you on the trail is essential.)
- Topozone
Topozone is a good option if you need maps quickly and you have a color printer to take full advantage of the topographical features. Topozone does not sell printed maps, but does provide methods to find and order printed maps from the USGS.
