4 Bear Hang Methods Backpackers Need When Parks Require a Canister
The main bear hang methods are the PCT (single-branch) hang, the Marrison counterbalance, the two-tree hang, and fixed bear poles or wires. Each works differently depending on terrain and tree availability, but a certified bear-resistant canister or Ursack often outperforms any hang and may be required by law in your destination. Read on for step-by-step instructions on each method plus how to check local rules before you commit to hanging your food.
TL;DR:
Proper hang placement requires a food bag at least 10 feet above ground and 4 feet from the trunk, with a tested knot and multiple angle checks.
The PCT method is lightweight and quick but relies on finding a suitable high, sturdy branch, which can be rare in young forests or above treeline.
When no single branch suffices, the Marrison counterbalance and two-tree methods offer secure alternatives, especially in forests with multiple medium-sized trees.
Fixed bear poles, wires, and lockers at established sites are often the most reliable and quickest options for food storage in managed campsites.
Carrying a certified bear-resistant canister is advised in grizzly country, in parks mandating hard-sided containers, or if recent bear activity and habituation are reported locally.

Comparing the main bear hang methods at a glance
Picking the right method starts with looking at what your campsite actually offers: tree spacing, branch height, and whether the park even allows hanging in the first place. Each technique below solves a different version of the same problem.
The PCT (single-branch) method works best when you find one tall tree with a sturdy branch jutting out ten feet or more from the trunk. It needs the least gear, just cord, a stuff sack, and a small throw weight, which makes it popular with ultralight backpackers on long trails. The tradeoff is that suitable branches are harder to find than you’d expect, especially in younger forests or above treeline.
The Marrison counterbalance method solves the “no perfect branch” problem by splitting your food into two bags that balance each other over a single point. It requires more rope handling and a stick or trekking pole to push the second bag up, but it works in trees where a single-branch hang would fail.
A two-tree hang uses a line strung between two trunks instead of relying on one branch’s strength and reach. It suits campsites with shorter, thicker branches where two trees stand close enough together, roughly 15 to 20 feet apart, to support a taut line.
Bear poles, wires, and metal lockers are the most reliable option when a campsite has them installed, since they’re built and maintained specifically for food storage. Established backcountry camps in bear country often provide one of these, and using it is almost always faster and more secure than rigging your own system.
Some situations rule out hanging altogether:
Grizzly country: standard hangs are frequently defeated by grizzly bears, and many agencies recommend certified canisters instead.
Park mandates: some parks prohibit hanging entirely and require hard-sided containers.
Treeless campsites: alpine zones, deserts, and burned forests often leave no viable anchor points.
Bear-habituated areas: campsites with a known history of bear activity call for the most secure option available, not the most convenient one.
Once you know which method fits your site, the next sections walk through exactly how to rig each one.
How to rig a PCT-style single-branch hang
The PCT method gets its name from its popularity on the Pacific Crest Trail, where thru-hikers need a fast, lightweight system they can set up in the dark after a long day. Backpacker’s PCT-style guide outlines the throw-hoist-toggle sequence that makes this method work, and it remains one of the most widely taught hangs in North America.
What you need:
40 to 50 feet of paracord or utility cord rated for at least 100 pounds
A small throw weight (a rock in a sock works, but a dedicated throw bag is more precise)
A stuff sack or dry bag large enough for all your food and scented items
A locking carabiner
A short stick or toggle about 4 to 6 inches long
Selecting your branch: Look for a live branch at least 15 to 20 feet off the ground that extends 6 to 10 feet from the trunk, with nothing beneath it that a bear could climb to reach your bag. Avoid dead limbs, which can snap under load, and avoid branches near a slope or rock face that would let a bear approach from above.
Step-by-step rigging:
Tie your throw weight to one end of the cord and toss it over the target branch, aiming for a point past the branch’s midpoint so the bag will hang well clear of the trunk.
Remove the throw weight and attach the carabiner, then clip your loaded food bag to it.
Hoist the bag until it reaches the branch, leaving several feet of slack cord hanging below it.
Tie a loop in the slack cord about arm’s length above the ground, then insert your toggle stick through the loop and push it up as high as you can reach.
Tuck any excess cord so it doesn’t dangle within reach, and step back to check that the bag hangs at least 10 feet up and 4 feet from the trunk and any climbable branch.
Test the hang by tugging firmly on the toggle stick to confirm the knot holds and the branch doesn’t sag dangerously.
Common mistakes include choosing a branch too close to the trunk, which lets a bear reach out and swipe the bag, and using a knot that slips under weight instead of a taut, tested loop. A trucker’s hitch or a simple slip knot at the toggle point works well because it releases cleanly in the morning without needing to climb or shake the tree.
Pro Tip: Practice the toggle-and-loop step at home in a doorway before your trip. It’s the one part of this hang that trips up first-timers in the field, especially in the dark.
Leave No Trace specifically recommends rehearsing hangs before relying on them in the backcountry, since fumbling with cord and knots at dusk leads to unsafe shortcuts. If you can’t find a branch that meets the height and distance targets, move on to the counterbalance or two-tree methods covered next.
Rigging Marrison counterbalance and two-tree hangs
When no single branch gives you the height and reach a PCT hang needs, two other methods can fill the gap using the same basic gear.
Marrison counterbalance method: This technique splits your food into two roughly equal bags and uses one to hoist the other, so the branch never has to be reachable from the ground once the hang is complete.
Divide your food and scented items into two bags of similar weight, tying one to each end of a single length of cord.
Throw the cord over a branch at least 15 to 20 feet up, then hoist the first bag until it’s just below the branch.
Tie off the remaining cord at chest height, then use a stick or trekking pole to push the second bag upward while releasing the tied-off section.
Continue pushing until both bags hang roughly level, several feet apart, with neither bag reachable from the ground or from the trunk.
Tuck or trim any excess cord so nothing dangles within reach of a climbing bear.
Two-tree hang: This method replaces a single strong branch with a line strung between two trunks, which works well where trees stand close together but lack long horizontal branches.
Choose two trees 15 to 20 feet apart with no low branches a bear could use to climb toward the line.
Anchor one end of a length of cord to the first tree at a height of at least 15 feet, using a sturdy knot like a bowline.
Run the cord across to the second tree and pull it taut before tying off, so the line doesn’t sag under the weight of your food bag.
Attach your food bag to the center of the line using a separate short cord and carabiner, hoisting or adjusting until the bag hangs at least 10 feet up and 4 feet from either trunk.
Secure the second anchor point at a height you can reach with a stick, avoiding low ties that put the whole system within a bear’s reach.
Counterbalance hangs suit forests with tall, branch-heavy trees where reaching a single high point with a throw weight is difficult. Two-tree hangs suit campsites with several mid-sized trees but no standout branches, and they distribute weight across two anchors rather than one, which reduces the chance of a single point of failure.
Using bear poles, wires, and lockers at established campsites
Some backcountry and front-country campsites remove the guesswork entirely by installing dedicated food storage hardware. Bear poles are tall metal poles with hooks or a pulley system near the top; bear wires are cables strung high between two poles or trees; bear lockers are metal boxes bolted to the ground, often found at trailheads and popular basecamps.
You’ll usually spot these near a cluster of tent pads or a central cooking area, sometimes marked with a small sign. Using them correctly matters as much as finding them:
Locate the hook or pulley mechanism, which is usually a metal ring or cable loop you pull down to attach your bag.
Clip your food bag securely using a carabiner, then hoist it using the pulley or push it up with the pole’s built-in mechanism.
Clear the area beneath the hardware of branches, rocks, or anything a bear could use to gain extra reach.
Share space courteously at shared sites by not overloading a single hook and by removing your bag promptly in the morning so other campers can use the system.
These fixed systems are generally preferred over improvised hangs because they’re built to a consistent height and distance standard, maintained by land managers, and tested against real bear activity at that specific location. If your site has one, use it instead of rigging your own line, even if you’d rather practice a PCT hang.
Building a hang kit and knowing when to skip it
Whichever method you choose, a few pieces of gear make the difference between a hang that holds and one that fails at 2 AM.
Cordage: 40 to 50 feet of cord rated for at least 100 pounds gives you enough length for most branch heights with slack to spare.
Throw weight: a dedicated throw bag or a rock in a sock lets you clear a branch on the first or second try instead of tangling cord in the canopy.
Carabiners: a locking carabiner keeps your food bag securely attached through wind and animal contact overnight.
Stuff sack or dry bag: a durable, odor-resistant sack keeps food dry and contains scent better than a loose grocery bag.
Bear-resistant canisters and Ursack sacks offer an alternative that sidesteps tree-finding entirely. The US Forest Service notes that properly used bear-resistant canisters are the most reliable method for preventing bears from accessing food, since they don’t depend on branch height, cord skill, or a bear’s unfamiliarity with hangs.
IGBC-certified products offer meaningfully tested protection. The Interagency Grizzly Bear Committee’s testing protocol lists nearly 500 certified products from over 100 manufacturers tested against grizzly behavior, meaning certification reduces the odds of a breach even though it doesn’t eliminate them entirely.
Canisters weigh more and take up pack space, which is the main reason experienced hangers stick with cord and a branch when they can. But if you’re traveling in grizzly country, an area with a history of habituated bears, or a park that mandates hard-sided storage, carry a canister even if you’re confident in your hanging skills.
Choosing a safe spot and getting the geometry right
A hang is only as good as its placement, and the same measurements apply no matter which method you use.
Target clearances: aim for a food bag at least 10 feet off the ground and 4 feet horizontally from the trunk or any climbable support. Leave No Trace’s hang guidance gives these measurements as the baseline for a hang that keeps food out of reach of a standing or climbing bear.
Choosing a safe tree:
Avoid dead limbs, which can snap without warning under the weight of a loaded bag.
Check for slope hazards below your chosen branch, since a bag swinging over a drop-off is harder to retrieve and riskier to rig.
Scan for rocks or debris that could be dislodged and struck by a falling bag or a mis-thrown weight, especially if other campers are nearby.
Rule out climbable supports, including nearby saplings, leaning trunks, or branches that form a ladder toward your hang point.
Rigging to minimize hazards: Stand well clear of your own throw line when tossing a weighted cord, since a mis-thrown weight can cause a real injury on the way down. Once the bag is hoisted, tug the line firmly to confirm the branch holds and the knot doesn’t slip before you walk away for the night.
Pro Tip: Do a final visual check from several angles, not just straight underneath. A bag that looks clear from one side can sit closer to the trunk than it appears from another.
Test every anchor point, whether it’s a branch, a two-tree line, or a counterbalance knot, by applying firm downward pressure before you consider the hang complete. A hang that holds under a hard tug is far more likely to hold against a curious or determined bear overnight.
When hangs are banned and canisters are required
Land managers don’t leave bear storage entirely up to personal preference, and knowing the rules for your destination matters as much as knowing how to tie a knot.
The Interagency Grizzly Bear Committee sets the testing standard that most parks and agencies point to when they recommend or require certified containers, since IGBC certification means a product has been tested against actual grizzly behavior rather than just marketed as bear-resistant. Some parks go further and mandate hard-sided canisters outright. The National Park Service requires approved storage in Yosemite’s backcountry, with significant fines for noncompliance in certain zones where hangs are specifically disallowed.
Forest Service districts issue their own Forest Orders that spell out local requirements and exceptions, and these can vary significantly between adjacent forests.
Before any trip, run through this checklist:
Check the specific park or forest’s regulations for your route, since rules differ even between neighboring wilderness areas.
Look into loan or rental programs, since some parks provide canisters at ranger stations or trailheads for visitors who don’t own one.
Plan for treeless terrain by carrying a canister you can wedge between rocks or secure to an immovable anchor, an approach some Forest Orders explicitly allow when trees aren’t available.
Confirm group-size rules, since some Forest Orders adjust storage requirements based on party size.
Enforcement varies by district, but rangers do check for compliance in popular bear country, and citations can carry real financial penalties on top of the risk to your food and the bear’s safety.
Why hangs fail and how to judge the real risk
Even a well-rigged hang isn’t foolproof, and understanding why helps you decide when to trust one.
Bears locate food primarily by scent, and a bag that looks sealed can still leak enough odor to draw attention from a distance. Agencies note that even airtight-looking setups can fail because bears detect scent through packaging and fabric that humans assume is sufficient. Habituated bears, meaning those that have successfully raided hangs before, pose the biggest risk since they’ve learned to test branches, chew through cord, or shake trees until a bag drops.
Common failure modes include:
Branches that are too close to the trunk, letting a bear reach the bag directly from the trunk itself.
Cord that’s too weak or worn, snapping under a bear’s weight if it climbs partway up the line.
Knots that slip under pressure, especially ones tied quickly in poor light without testing.
Hangs left too low, often the result of misjudging branch height in the dark.
If your campsite has a known history of bear activity, or you’re in a region with a habituated bear population, a certified canister removes most of these failure points since there’s no branch, cord, or knot for a bear to exploit.
Practitioner tips for faster, safer hangs in the field
Getting comfortable with these methods before you need them changes how a hang actually goes at camp. Set up your PCT rig in your backyard or a local park a few times before your trip, timing yourself so you’re not fumbling with cord after a 12-mile day.
A few habits make a real difference on the trail. Repack meals into odor-resistant resealable bags rather than relying on their original packaging, since scent management is often the weakest link in an otherwise solid storage system. Store toiletries, sunscreen, and anything scented with your food rather than in your tent, since bears don’t distinguish between food smell and other strong odors. For group trips, split food across multiple bags or containers rather than one oversized load, which also makes counterbalance hangs easier to rig since you’re not searching for a perfectly matched second bag.

Pair your hang practice with a look at meal packaging ideas that repackage well and fit tightly into a stuff sack or canister without wasted space.
Fixing a hang gone wrong at camp
Sometimes a hang doesn’t go as planned, whether that’s a branch that turns out too low or a knot that won’t hold. Here’s how to handle it without wasting daylight or risking an injury.
Reassess the branch or anchor if your first attempt sags too low or sits too close to the trunk, and move to a backup tree rather than forcing an unsafe hang.
Switch methods if needed, dropping a PCT attempt for a two-tree hang if you can’t find a single suitable branch nearby.
Recheck your knots by applying firm pressure before walking away, retying anything that slips even slightly under a hard tug.
If you truly can’t rig a safe hang, secure your food in whatever hard-sided container you have, wedge it between rocks or tie it to an immovable anchor well away from your tent, following the approach some Forest Orders permit for treeless terrain.
Contact a ranger station or land manager if you’re in an area with recent bear activity and no safe storage option, since some districts can advise on alternate sites or provide loaner canisters.
If you do encounter a bear at your site despite these precautions, our guide to bear encounters walks through how to respond calmly and reduce further habituation risk.
When I hang and when I carry a canister
My rule of thumb comes down to two questions: how many bears have been reported in this area recently, and does the campsite have a track record of food-related incidents? If either answer raises a flag, I carry a canister regardless of how confident I am in my knot work. In low-traffic backcountry with no known bear history, a practiced PCT or counterbalance hang is fine, but I still test the anchor every single time rather than assuming last trip’s technique will hold.
My minimum practice routine before any trip into bear country is three full run-throughs of whichever method I plan to use, timed, in daylight, before I ever need it after dark. For deeper technique and a printable checklist, our bear bagging guide and our survival skills collection cover the rest of what a solid food storage routine looks like.

FAQ
How do you properly do a bear hang?
Choose a live branch at least 10 feet off the ground and 4 feet from the trunk, following the clearances Leave No Trace recommends. Throw a weighted cord over the branch, hoist your food bag, and secure the line with a tested knot before checking the hang from multiple angles.
What is the 3 bear rule?
There isn’t an official “3 bear rule” recognized by land management agencies. If you’ve heard the phrase used informally, it likely refers to general food storage caution rather than a specific standard from the National Park Service, US Forest Service, or IGBC.
Are bear hangs effective?
Bear hangs can work when rigged correctly, but agencies note that properly used bear-resistant canisters are more reliable in many areas. Habituated bears in particular have learned to defeat simple hangs, which is why some parks require certified containers instead.
What smell do bears hate the most?
There’s no widely documented scent that reliably repels bears, and relying on one is not a substitute for proper food storage. The National Park Service instead recommends storing all scented items, including toiletries and food, with the same care to avoid attracting bears in the first place.
Is a bear canister better than an Ursack?
Both can be effective when IGBC-certified, but a hard-sided canister generally offers more consistent protection since it removes the scent and texture cues a bear might associate with a soft-sided sack. Choose based on your route’s regulations, since some parks specifically require hard-sided canisters and won’t accept an Ursack as compliant.
