How to Hang a Bear Bag: PCT Method, Counterbalance, and Everything You Need to Know

Bears are the most famous reason for hanging food, but they are far from the only threat. Raccoons, mice, marmots, jays, and even deer will raid an unprotected camp kitchen. In heavily trafficked backcountry areas, these animals have learned to associate humans with free meals, and an unsecured food bag sitting on the ground or inside your tent is an open invitation.

Protecting wildlife is the primary goal. When a bear gets human food, it learns that people equal easy calories. That bear returns to campsites, grows bolder, and eventually becomes a “problem bear” that land managers are forced to relocate or euthanize. A single careless food storage mistake can start that cycle. Proper food storage in the backcountry is not just about protecting your dinner — it is about keeping wildlife wild.

Hanging your food is also a core Leave No Trace principle. The seventh principle — "Be Considerate of Other Visitors" — extends to wildlife. A habituated bear at a popular campsite affects every hiker who camps there after you. Beyond ethics, many areas carry fines of $500 or more for improper food storage.

From a practical standpoint, losing your food supply to animals on a multi-day trip can turn an inconvenience into an emergency. If you are three days into a five-day backpacking trip and a raccoon shreds your food bag overnight, you are facing a long, hungry hike out. Our backpacking food guide covers meal planning and calorie needs — all of which assumes your food actually makes it through the night.

Most people think a bear bag is just for food, but the rule is broader: anything with a scent goes in the bear bag. Bears have a sense of smell roughly 2,100 times stronger than a human’s. They can detect a candy bar wrapper from over a mile away. Here is what needs to go in:

The PCT method — named because it is widely taught to Pacific Crest Trail hikers — is the most reliable single-rope bear bag hanging method for solo backpackers. It uses a stick as a toggle to lock the bag at height, so you do not need to tie off to the tree trunk (which smart bears have learned to untie). Here is how it works:

The counterbalance method uses two equally weighted bags to balance each other over a branch. It is the traditional bear bag hanging method taught by many outdoor organizations and works well when you have enough food to split into two roughly equal bags. Here is the process:

A bear hang requires surprisingly little gear, and most of it is lightweight. Here is your bear bag kit list:

A bear canister is a hard-sided, barrel-shaped container that bears physically cannot open. They weigh between 1.5 and 3 pounds depending on size and material, and they are the most foolproof food storage in the backcountry method available. The trade-off is weight and bulk — a canister takes up significant space in your pack.

Where canisters are required by law: Several areas in the United States legally require bear canisters, and a bear bag is not an acceptable substitute. The most notable include Yosemite National Park, Sequoia and Kings Canyon National Parks (SEKI), large portions of the Sierra Nevada backcountry including the John Muir Trail, and Olympic National Park. Rangers enforce these rules, and fines typically range from $150 to $5,000.

Even where canisters are not legally required, they are often the smarter choice. In areas with heavy bear activity — the Adirondacks, parts of the Smoky Mountains, Glacier National Park — bears and raccoons in popular campsites have learned to defeat bear hangs. A canister eliminates the skill and tree-finding variables entirely. You just close the lid, set the canister on the ground 200 feet from camp, and go to sleep.

Popular canister options include the BearVault BV500 (the most widely available and affordable at around $80), the Lighter1 Big Daddy (lightest option at 1.6 pounds), and the Garcia Backpackers’ Cache (virtually indestructible and often available for rent at ranger stations near canister-required areas).

The Ursack is a bear-resistant bag made from Spectra fabric — the same material used in bulletproof vests. It weighs about 7.6 ounces for the Major model, far less than any hard-sided canister, and it packs flat in your backpack instead of taking up a rigid cylinder of space.

How it works: you fill the Ursack with your food and scented items, cinch it closed with the integrated aluminum closure system, and tie it to a tree trunk at ground level using the built-in tie-out loops. A bear can bat it around and chew on it, but the Spectra fabric resists tearing. The food inside may get crushed, but the bear cannot access it.

The catch: Ursack acceptance varies by jurisdiction. Some areas that require hard-sided canisters do accept the Ursack Major as an approved alternative (it is IGBC certified). Others do not. Yosemite, for example, does not allow Ursacks — hard-sided canisters only. Always verify before your trip. The Ursack website maintains an up-to-date list of where their products are approved.

For hikers who find bear hangs frustrating and canisters too heavy, the Ursack is an excellent bear bag alternative. Pair it with an Opsak odor-barrier bag inside for the best protection. If you are building your gear list for a first backpacking trip, our backpack sizing guide helps you figure out how much space you need for food storage alongside the rest of your kit.

The standard guidelines for bear bag placement are known as the 12-6-6 rule. Your food bag should hang:

Food storage rules vary widely across the United States, and ignorance is not a valid defense if a ranger checks your camp. Here is a summary of the most important regions and their requirements:

A bear hang is only effective if it is done correctly. These are the mistakes we see most often in the backcountry — and the ones bears have learned to exploit.

Hanging a bear bag requires trees, which means the method fails entirely above treeline, in alpine meadows, desert environments, and tundra. If your route passes through these zones, you need a different strategy.

Bear canisters are the default above treeline. In the Sierra high country, Rocky Mountain alpine basins, and above-treeline sections of the PCT and Continental Divide Trail, a hard-sided canister is your only reliable option. Place it on flat ground at least 200 feet from your tent. Some hikers wedge it between rocks to prevent a bear from rolling it downhill — a frustrated bear will bat a canister around for up to an hour before giving up.

Bear poles and cables. Many popular backcountry campsites in grizzly country provide metal bear poles — tall steel posts with hooks at the top — or cable systems where you clip your bag to a wire strung between poles. These are common in Glacier National Park, Grand Teton, and along sections of the Appalachian Trail. When bear poles or cables are available, use them. They are more effective than any field hang.

The Ursack option. In treeless terrain where canisters are not required, an Ursack tied to a large boulder, rock pile, or metal ground anchor is a viable solution. The bag resists tearing even if a bear chews on it for hours. Just accept that the food inside may be crushed.

Whatever method you choose, plan your food storage strategy during trip planning, not when you arrive at a treeless campsite at dusk. Check maps for the treeline elevation on your route — in the Rockies, treeline is typically around 11,500 feet; in the Northeast, it can be as low as 4,500 feet.
