Using Tarps and Flies for Backcountry Camping
Alternative Shelters for Hiking and Backpacking
Apr 8, 2009
Not every backpacking trip requires using a tent for a shelter. Tarps and flies are much lighter, cheaper, and can still provide protection for backcountry hikers from the elements.
Plastic Tarps vs. Nylon Flies
A plastic tarp is cheap and can be found not only at outdoor gear stores, but also at hardware stores and military surplus stores. Most plastic, heavy-duty tarps have metal grommets along the edge. These allow the user to tie nylon cord to the tarp. The cordage can then be stretched out and staked down or tied to a tree. A second tarp can be laid on the ground to keep the sleeping bag dry. The disadvantage of tarps is that they can wear out quickly, and don’t come with a warranty for damage.
A nylon camping fly, such as the Integral Designs Siltarp, can do the same job as a plastic tarp. Its main advantage is that it can be lighter and more compact than a plastic tarp, depending on the size. This could mean a big difference for lightweight backpackers who need an individual shelter. The main disadvantages are that a fly is more expensive, and can not be used as a ground cloth.
Setting up Tarps and Flies
A basic setup for a tarp or fly is an A-frame design. This method covers a large amount of ground while also providing a way for rainwater to flow off the shelter. Spread the shelter out and attach cord at the corners and on either end of the middle of the tarp or fly. Tie the middle lines first, then stake out the four corners.
A low impact way to set up the middle is by using two trekking poles that have been extended. This way, one doesn’t have to use a tree, which could mark up the bark, especially birch or aspen trees.
When and Where Tarps and Flies Can Be Used
Tarps and flies can be used all four seasons, although the best time is during the spring, summer, and early fall. These are times when hikers want to cover long distances, and are looking to cut their pack weight. A tarp or fly will not provide any warmth during the winter, but they could be incorporated into a snow shelter. Another time when these shelters may not be as useful is when there are a lot of insects out, such as black fly season in Maine or mosquito season in Alaska.
Things to Consider When Buying a Tarp or Fly
When buying a shelter, consider these ideas before taking one into the backcountry.
- Know what size will be needed. How many people will be using the shelter? One? Two? Three? A 10x12 will work for one person. Note that the larger the tarp, the heavier it will be.
- Stretch out the shelter at home before taking it on the trail and attach cord to the grommets or lash points. Melt the ends of the nylon cord with a lighter to prevent future fraying.
- Practice setting the shelter up in the backyard.
Using a fly can not only save weight when hiking on the trail, but also money when buying a backcountry shelter.
