Bear safety at the campsite: food storage, spray and common sense
What the National Park Service advises for campers in black bear and grizzly country: storage rules, bear spray, distances and encounters.

Most nights in bear country pass without incident, and the reason is largely dull: food is stored properly, cooking is done at a sensible distance, and nobody leaves a cooler on the picnic table. Bears that learn to associate campsites with food become a danger to people and are often relocated or killed, which is why park rules on food storage are strict and why rangers insist that every wildlife conflict be reported.
This guide covers what national park guidance says for campers in the United States, with examples from Glacier, Yellowstone and Grand Teton, where black bears and grizzlies share the same landscape. The park's own page and the ranger at the entrance remain the final word on local rules.
Two species, one rule on distance
Glacier and Yellowstone have both black bears and grizzly bears. Size and color are unreliable clues, since black bears can be brown and grizzlies can be dark. The park service points to shape instead: a grizzly has a shoulder hump, a dished face, rounded ears and light-colored claws, while a black bear has a prominent rump, a straight snout, pointed ears and dark claws. Both parks ask visitors to stay at least 100 yards (91 m) from bears and wolves and 25 yards (23 m) from other wildlife such as bison and elk. Glacier's test is simple: if the animal changes its behavior because of the visitor, the visitor is too close.
Food storage at the campsite
The core rule is that nothing with a smell stays available to a bear. At Grand Teton the requirement is that all food, garbage, pet food, coolers, food containers, empty or full, and cookware, clean or dirty, are stored in a hard-sided vehicle with the windows closed or in a bear-resistant locker whenever not in immediate use. Glacier gives the same advice and adds toiletries and sunscreen to the list, and warns against throwing food waste into pit toilets. Yellowstone includes drinks, coolers, toiletries and menstrual products, and accepts lockers or certified bear-resistant containers.
A tent is not a hard-sided vehicle, so tent campers need the locker or a container. A motorhome or van with solid walls, closed windows and closed roof vents counts as hard-sided storage under the Grand Teton rule, but a pop-up or tent trailer may not, so the question is worth asking at the entrance. Trash goes into the bear-proof bin or the dumpster at once, never into a fire ring, and food stays within reach only while it is being eaten.
Cooking, sleeping and cleaning
Smells travel, and the habits that reduce them are inexpensive. Cook and eat at the picnic table, change out of clothes that smell of food before bed, and wash up straight after the meal. Yellowstone's backcountry guidance is to sleep at least 100 yards (91 m) from where food is cooked and eaten and to scatter dishwater 100 yards from tent sites; in a campground, the equivalent is to keep cooking at the table, away from the sleeping area as far as the site allows. Pet food is stored like human food.
Bear spray
Bear spray is the most effective deterrent according to Glacier, and Yellowstone advises one can per person in a holster that can be reached in a second, not at the bottom of a pack. It must be a product registered with the EPA and in date. The advice is to deploy it when the bear is about 30 to 60 feet (9 to 18 m) away, aiming to create a cloud between bear and person. It should never be sprayed on the body or tent as a repellent. Stored temperatures should not exceed 120°F (49°C), which a closed vehicle in summer can exceed, so the can belongs in the cabin rather than the roof box.
Spray cannot normally be flown. Airline and TSA rules prohibit or restrict it, and the usual solution is to buy one on arrival: Yellowstone says it is sold in park gift shops and outdoor stores and can be rented at Canyon Village and Old Faithful. Bear bells, according to Glacier, are not effective; talking and clapping on trails is better.
If a bear appears
The park service advice is the same for most situations: stay calm, speak in a normal voice so the bear identifies a human, back away slowly, avoid direct eye contact and never run, since bears can sprint as fast as racehorses. Never get between a female and her cubs. Groups are safer: Glacier reports no attacks on groups of four or more, and Yellowstone found that 91 percent of its bear-related injuries involved hikers who were alone or in pairs.
If a bear actually attacks, the response depends on the species. For a grizzly the NPS advises playing dead: lie flat on the stomach with hands clasped behind the neck. For a black bear it advises the opposite: do not play dead, escape to a car or building if possible, and fight back if not. Since species can be hard to tell in a second, recognizing the hump and the face before a trip is more useful than learning the rule afterwards.
Before leaving camp
A short routine covers most of it: ask at the visitor center about recent bear activity and closures, put away every item with a smell before leaving for a hike, carry the spray where it can be reached, hike in a group and make noise on blind corners, and report any bear that approaches the site to a ranger. Check the park's bear page for the park in question, since Yellowstone, Glacier and Grand Teton publish their own rules and update them each season.
