Key takeaways
- A bear bag protects food by hanging it from a tree branch, out of a bear's reach.
- Common methods: the PCT method (with a stick/toggle) and the counterbalance.
- Aim for roughly 12 ft high, 6 ft from the trunk, and 6 ft below the branch.
- Lighter and cheaper than a canister, but needs good trees and skill — and is banned in some areas.
What a bear bag is
A bear bag is a method of protecting food and scented items from bears (and rodents) by hanging them from a tree branch, out of reach. Done right, it keeps your food safe and — just as importantly — keeps bears from getting human food that would make them dangerous, the same goal as a bear canister.
Methods and how high
Common techniques include the PCT method (using a stick or toggle to lock the bag high on the line) and the older counterbalance (two bags balanced over a branch). The widely cited target is the 12-6-6 rule: at least 12 ft off the ground, 6 ft out from the trunk, and 6 ft below the branch — putting the bag beyond a standing, climbing, or branch-walking bear.
At a forested camp, a hiker tosses a line over a high, sturdy branch well out from the trunk, ties on their food bag, hauls it up to about 12 feet, and uses the PCT method to lock it off — keeping all scented items off the ground overnight.
Bear bag vs canister
A bear bag is lighter and cheaper but needs good trees, skill, and time, and is banned in some areas (and useless above treeline). A canister is heavier but foolproof and works anywhere. See bear canister vs bear bag, and always check local food-storage rules.
The bottom line
A bear bag is the lightweight, low-cost way to protect food in the backcountry — when you have the right trees and the technique to hang it correctly (think 12-6-6). It demands more skill and the right environment than a foolproof bear canister, and it's banned in some areas, so always check local rules and have a backup plan.
Frequently asked questions
What is a bear bag?
A bear bag is a way to keep food safe from bears by hanging it in a bag from a tree branch, high enough and far enough from the trunk that a bear can't reach it. It protects your food and helps keep bears from learning to associate humans with meals.
How high should you hang a bear bag?
A common guideline is the 12-6-6 rule: at least 12 feet off the ground, 6 feet out from the tree trunk, and 6 feet below the branch it hangs from. The goal is to put the bag out of reach of a bear standing, climbing the trunk, or going out along the branch.
Bear bag or bear canister?
A bear bag is lighter, cheaper, and packs small, but it requires suitable trees, takes skill and time to hang correctly, and isn't allowed everywhere; a bear canister is heavier and bulkier but foolproof, works anywhere (even above treeline), and is required in many areas.
