Coil a Rope Properly
A tangled rope is a wasted rope. The butterfly coil is the backcountry standard for a reason: it stores clean, deploys clean, and a ten-year-old can learn it in a single afternoon. Five minutes of practice in the backyard pays off every time you hit the trail.
This page from Outside, the family adventure app, teaches families how to coil a rope using the butterfly coil method, the preferred technique for hikers, climbers, and outdoor educators. It covers the step-by-step coiling process, a short practice drill for kids and parents together, and real-world situations where a properly coiled rope proves useful. The page is written for families with children ages 4 to 14 and can be learned in five to fifteen minutes.

Why the butterfly coil beats every other method
Most people coil rope the way they coil a garden hose: round and round into a flat spiral. That method twists the rope's fibers with every loop, and when you throw it out or uncoil it in a hurry, you get a snarl. The butterfly coil, sometimes called the backpacker's coil, adds loops in alternating directions. Each loop offsets the twist of the last one, so the rope comes out straight and ready to use. It also carries well: finished butterfly coils can be slung over a shoulder or clipped to a pack. Climbers, search-and-rescue teams, and wilderness guides use this method for a simple reason. It works.
What you need before you start
Any rope long enough to matter will do for practice. A 30-foot length of paracord or a standard throwing rope is ideal. A full-length climbing rope works too, though it takes a little longer. You want rope that is reasonably clean and dry. Wet or muddy rope is harder to handle and teaches sloppy habits. Clear a patch of grass or a clean floor. That is the entire setup. No tools, no special hardware, no cost beyond the rope you likely already own.
How to coil: step by step
Start by finding the middle of the rope. Fold it in half so both ends meet. Hold that midpoint in your non-dominant hand, letting the doubled rope hang down.
- Draw up a large loop, roughly elbow to fingertip in length, and drape it over your hand. - Bring up the next loop from the opposite side of the doubled strand, crossing over the first. - Keep alternating sides with each new loop, matching the size as closely as you can. - Continue until about two feet of rope remain at the top. - Wrap that tail around the coils several times, moving toward the top loop. - Push a bight (a small fold of the tail) through the top loop and pull it snug. - Thread the remaining end through that bight and cinch it down.
The finished coil should hold its shape when you set it on the ground.
Practice drill: the twenty-second toss
Once the coil is finished, the real test is how fast it can be undone and recoiled. Run this drill as a family.
Step one: one person throws the coiled rope onto the grass and the other unclips or unties the tail, gives the coil a single shake, and lets it fall open. Time how long it takes to get a tangle-free line.
Step two: recoil using the butterfly method and record the time.
Goal: a clean uncoil in under five seconds and a full recoil in under two minutes. Kids 8 and up usually hit that target after two or three tries. Younger children can practice the looping motion on a shorter cord while an adult handles the finishing wrap. Make it a relay: one person coils, hands it off, the next uncoils.
When you will actually use this
Knowing how to coil a rope properly shows up more often than most families expect.
- Throwing a rope bag across a creek or to a swimmer in moving water: a clean coil separates and flies true. - Setting up a bear hang at camp: a snarled rope in low light is a genuine frustration. - Rappelling or top-rope climbing at a crag: guides and instructors notice immediately when a family arrives with rope that is ready to use. - Packing out quickly: a coiled rope clips to a pack in seconds and does not snag on brush. - Teaching younger siblings: older kids who can demonstrate a skill are more confident on the trail and more helpful at camp.
Keeping the habit going
The butterfly coil only stays useful if it becomes automatic. The simplest rule: never put a rope away uncoiled. After every use, whether it is a ten-foot jump rope in the backyard or a full climbing line at the crag, coil it before it goes into the bag. That habit takes about three consistent outings to stick. Some families hang their coiled ropes on a hook near the gear locker so the coil itself is the reminder. However you reinforce it, the payoff is real: you will never stand at a trailhead unknotting rope while the morning light disappears.

Frequently asked questions
What is a butterfly coil and why do hikers use it?
A butterfly coil is a rope-coiling method where each loop alternates direction, which cancels out the twisting that causes tangles. Hikers and climbers prefer it because the finished coil deploys cleanly with a single shake and can be carried over a shoulder or clipped to a pack.
What age can kids learn to coil a rope?
Most children can follow the alternating-loop motion starting around age 6 with some guidance. By age 8 or 9, many kids can complete a full butterfly coil on their own. Younger children enjoy practicing the looping motion on a short length of cord even before they handle a full rope.
Does it matter what kind of rope I use to practice?
Any rope of reasonable length works for learning the method. Paracord, a throw rope, or a standard climbing rope are all fine. Avoid very stiff or very slippery ropes for a first lesson, as they make it harder to keep the loops even. A clean, dry rope in the 20 to 50 foot range is ideal for family practice.
Can you carry a butterfly coil on your back?
Yes, and that is one of its main advantages over a flat coil. Once the tail is wrapped and secured through the top loop, you can slip both arms through the coil like a backpack, or sling it over one shoulder. It sits close to the body and stays put on the trail.
