Pitching options for a square tarp, specifically for hammock camping.
I think a square tarp is probably the most modular for hammock camping because it can be pitched in so many different configurations. It really is a workhorse item because you can create nearly everything from a fair-weather sun shade to a storm-worthy, snow-shedding A-frame fortress. Keep in mind that you’ll need to carry a little more guy line and a few stakes in order to configure some of these options.
If the tarp is the right size (as large or larger than 10×10 ft/3.05×3.05 m), you can hang multiple hammocks under one tarp to share some gear and save some weight.
