Tarps & Rain Flies

A dining fly — a big tarp pitched overhead — is the camp's rain shelter and gathering hub. Attach a guyline to each corner, raise it on a ridge line between two poles or trees, and tension everything taut so it sheds rain and doesn't flap.

How to set one up

  1. 1Lay out the tarp over the area you want to keep dry.
  2. 2Attach a guyline to each corner with two half hitches or a bowline.
  3. 3Pound in stakes about 5 feet away, at ~45° from each corner.
  4. 4Tie taut-line hitches between the stakes and the tarp's corner grommets (these let you re-tension later).
  5. 5Build the uprights — join two Scout staves with round lashings for each pole (or use trees).
  6. 6Rig the ridge line — secure it to the poles with half hitches, run it over the tarp's center, and stake the ends.
  7. 7Raise the tarp and tension all the guylines so the fly is taut and pitched to shed rain — no sags where water can pool.
  8. 8Tree option: tie guylines to nearby trees instead, but pad the trunk so the rope doesn't damage the bark.

When to use it

  • Rain shelter over the cooking and eating area — the classic patrol dining fly.
  • Sun shade in hot weather and a dry hub to organize camp around.
  • Tarp shelters for sleeping (lean-to, A-frame) in ultralight and survival setups.

Common mistakes & safety

  • Pitch it taut and angled so water runs off. A sagging tarp pools water that gets heavy, drips, and can collapse the fly.
  • Stake and guy for the wind. A loose tarp is a sail — a poorly staked fly can pull out, whip around, and hurt someone or wreck the tarp.
  • Watch head height and trip lines. Set the fly high enough not to walk into, and guylines where people won't trip (flag them if needed).
  • No open flame right under a tarp. A stove flare under a synthetic tarp is a burn/melt hazard, and enclosing a stove risks carbon monoxide.
  • Protect the trees. Pad any trunk you tie to so the rope doesn't girdle the bark — a Leave No Trace rule that keeps the tree healthy.
  • Mind lightning. A tarp is not lightning protection — in a storm, the campsite and lightning rules still apply.

Going deeper

  • Angle beats flat. Even a "flat" dining fly should be pitched with a slight slope so rain sheds instead of pooling — a pooled tarp holds shocking amounts of water.
  • A tarp is a whole shelter system. The same tarp-and-guyline skills make lean-to and A-frame sleeping shelters for lightweight camping.
  • Trucker's hitch for tension. Many campers finish a ridge or guyline with a trucker's hitch for extra mechanical tension; the taut-line hitch is the adjustable standard.
