Tarps are one the hikers greatest (and oldest) tools to have with them on any long distance hike. Although some trekkers may prefer the more traditional tent, tarps are seen as the jack-of-all-trades. It is light, portable, and can be tucked into a pack without much space needed for it. The most convenient part about a tarp though, that I think you will appreciate the most, is the ability to create a shelter in any situation! You can use anything that is around you, trees, roots, or even your own gear to set up your tarp.
