Each campsite and canvas tent cabin in Yosemite, (as well as some trailheads and parking lots), has a metal food storage locker (bear box).
This page gives you ideas on how to use one, including some logistics on sharing one in a large group.
Sizes of the bear-raccoon-coyote proof (if used properly) food lockers are near the end of this webpage.
Yosemite warns: “Improper food storage may result in impoundment of your food or car, a fine of up to $5,000, and/or revocation of your camping permit.”
Bears break into vehicles (including car trunks), tent-trailers or tents to get at food or even containers shaped like food seen through the windows, so campers need to put all food, ice chests, toiletries, stoves with spilled food, water bottles that had lemonade mixed in them, trash that didn’t quite get to the bear-proof dumpster, pans and dishes in the bear box.
To see bears breaking into cars and get the most current advice, watch the video at:
Clean out your car . . .
You can’t trust your own nose; look around the car, including under the seats for that one old stale, french fry, and in the glove compartment, thoroughly. Take the gum wrappers out of the ashtray. Hey, no heavily scented air fresheners hanging from the rear-view mirror!
If the child seat has food spilled on it, scrub it before the trip. Some parks recommend leaving it sitting outside of the car and/or tent overnight or when away from the campsite and not actually using it, so plan ahead for a rain-proof cover.
No bottle of brake fluid or spray can of deicer showing, the bears don’t know it’s not food and will break into your car because they see an item the shape of a food container. Remove night crawlers or salmon eggs from the fishing gear.
Air out your vehicle if you eat burgers on the way to the park.
Playing a bean bag toss game? Yup, a bear ate the beans from bean bags from a game people left out, so either think of a different game to play or put the bean bags in the food locker.
That pumpkin you carved for Halloween is also food.
The carrot stick you want to use for a nose on a snowman is also food, so use a stick instead.
The mini-lock on the tent zipper is useless, animals will just tear the tent fabric.
When you arrive and as you unpack the open truck bed, leave someone with the gear. Don’t leave a car door open while you go back and forth unpacking.
Get the food/toiletries out of your vehicle right away when you arrive at the campsite/ tent cabin / hotel room. In 2005 Yosemite started warning: “Bears break into cars during the day time. So even while on a day hike, store all scented items in lockers.” Bears are not true hibernators, so they break in to cars in the winter.
The food storage boxes usually have one or two latches that bears can’t open, but the bears will try!
From The Bear Facts (July 13 – July 19, 2003)
“Six vehicles were damaged by a bear in the Curry Village” (Half Dome Village) “area last week, all vehicles contained food.
A large untagged/uncollared bear has been seen in Upper Pines and the Wilderness Lot, checking for improperly latched food storage lockers. Visitors have reported this bear going from site to site, banging on the locker latch. Unfortunately, the bear obtained food on at least three occasions from improperly latched lockers.”
Typical mistakes people make with bear boxes include:
Overstuffing the box and not being able to really shut it tight. On some models a bear might not get the door open, but a raccoon can reach in through the crack, snag food bags with his paws and make a mess all over the campsite overnight.
Assuming that because people are in the site the doors don’t have to be latched all the time is a big mistake. Bears (and lots of raccoons) enter campsites during meals to try to get food off picnic tables, from vehicles with doors open or from bear boxes that weren’t latched. Don’t turn your back on food, keep it within arm’s reach.
Don’t leave bear box door open beyond the time it takes to get out what you need.
Don’t open it and turn away to carry food to the picnic table without shutting and locking it.
Don’t leave items sitting on top of the bear box unless you are standing right there eating them, for example.
From a Yosemite Daily Report of June, 2004:
“Bears are getting food from visitors that are too far from their food.(Farther than arms length is too far and any food behind the back is an invitation.) ”
If you are only making and eating a sandwich, for example, you can do the food prep on top of the food locker, shut and latch it and sit down to eat.
But if you are cooking food, especially with multiple courses, you need at least one partner. The two of you look in the storage locker for what you will need. Then perhaps you move out the ice chest/cooler (and shut/latch the door behind you as you move it to the picnic table). One of you can sit at the picnic table with what is being brought out, while the other goes back to get more things. (It could be wise to take a bathroom break just before you start making a meal, since one of you will need to stay with everything (and that campfire you started as well) if the other leaves the campsite.)
No, you r-e-a-l-l-y should not leave the door open as you go back and forth from the food locker to the picnic table, even if you are sure you do not see any animals in the vicinity. Raccoons can be especially fast getting in and out of food storage lockers.
When camping with a large group of people we have found that some complain there is not enough room in their shared bear box for all their gear. In the summer at Tuolumne, when we often get a group campsite, we have had serious problems fitting everything. For many years on our winter Yosemite valley trip the Rangers let us use bearboxes in closed campsites in the rest of the campground, but in 2004 a Ranger said we would need to buy more campsites instead and that has been the policy ever since. And no, it would not be a great idea to just sneak your excess food into a bearbox in a vacant loop, if they get more campers and open up more loops, you could lose your food, ice chest, etc.
The size of the bear box (most are 35″ deep x 43″ wide x 28″ tall, some are 33″ deep x 45″ wide x 18″ tall, according to the the Yosemite website) lets you plan what you can bring. The front opening sometimes has a flange around the inside of the opening. The inside is actually a little bigger.
Measure your ice chest in advance. Some mega-quart capacity coolers are 19″ tall and won’t fit in.
Plan in advance to use the space available more effectively.
This page pictures the smaller boxes, the newer, larger ones are slightly less wide, but slightly deeper and ten inches taller. Picture a 33 inch by 45 inch space. Then imagine two ice chests slid into the back of the bear box.
Along come more people and they place a stove, two pans, five shower kits of various shapes and sizes, two paper grocery bags of canned/boxed food, a six-pack of soda, a small toiletries duffel bag, a tea kettle, a dish pan with a few things in it and a small shallow box of miscellaneous cooking gear in front of the ice chests.
When the people who put in the ice chests need something from them they need to take out all these individual items. When they put them back in they will doubtlessly not put them back in order.
At some point the paper grocery bags will get damp on the bottom from leakage from the ice chests or blown in rain/snow and will disintegrate when they are removed. Cardboard boxes that get wet on the bottom can also disintegrate, even over only one weekend.
More things could fit if everyone brought their gear in shared small, deep plastic trash cans or other plastic boxes close to, but no more than, 17 inches tall. A typical bedroom waste receptacle could be 9″ by 12″ by 17″ tall and hold quite a few cooking items and toiletry bags. Then more gear could fit, since it would not all be spread out in a shallow layer and all of it could be retrieved and replaced more easily.
A big bin, like the blue 23 1/2″ x 16″ by 16 1/2″ tall one pictured below, can hold a large number of single items for multiple people.
If a big group does not have all the same menu, they should at least plan some ways to have more space by bringing less. If everyone who wants to make sandwiches brings their own 32 ounce jar of mayo and 16 ounce jar of mustard, we will run out of space in the bear boxes. Share condiments or bring small containers.
Likewise, put some cereal in a smaller container instead of each person bringing a full-sized box. Don’t bring a gallon of milk, start with a maximum of a quart and then buy more at the store. You probably don’t need a two pound block of cheddar. Can you bring instant drink mixes and mix as you want them instead of a gallon bottle of punch or lemonade?
If you cook chicken in advance and bone it it will take up a lot less space. (If you bring uncooked chicken you risk the juice leaking into the ice chest and the possible Salmonella contaminating all your food.)
If you break the eggs for scrambled eggs into a tightly lidded jar they take much less space than in the carton they came in from the store. In the photo below, the jar has eggs, a little grated cheddar, sour cream and chives. It’s ready to be shaken and turned into scrambled eggs or an omelet. And the eggs store more easily in the jar when in an ice chest than in the package they came from the grocer in.
The prewashed and precut raw bell pepper, celery and cauliflower in the plastic container lasted for days and take less space than whole vegies.
All the food preparation you do in advance means more time to play on the trip.
If everyone brought a large container of full-sized toiletries, as in the left of the photo below, they would take up too much space. By bringing travel/sample sized containers of shampoo, lotion, etc. in a smaller bag, as in the example on the right in the photo below, there is room for even a full sized can of spray insect repellent.
NO!→ ← Yes!!
Tear off the appropriate size and number of sheets of foil you will need, fold and pack them with a few plastic sandwich bags as needed instead of bringing whole packages.
Yes! → ← No
Antibacterial towelettes are great to clean hands when it’s just not convenient to trudge to the restroom before preparing a meal. But the whole plastic tub will take up too much space in the bear box, bring a few in a zip-lock bag, or a small bottle of liquid.
Yosemite rules say to dispose of all trash in the dumpster, not to store it in the bear-proof campsite food storage box. And it probably won’t fit in the box anyway. So, make regular trips to the bear-proof dumpster.
Yosemite has recycling bins near many of the restroom dumpsters.
At the end of each campsite loop in Upper Pines campground, for example, there are trash and recycling dumpsters, and at the end of some of the loops, a smaller trash-can-sized receptacle for propane canister recycling only.
Please use the clip on the trash bin to lock it (and if you walk by and notice it is not clipped, please clip it!):
As of June 2016 a new rule was added in Yosemite:
“If a park-provided food locker is full, the occupants of that site or unit may store a clean ice chest that is empty, or contains only plain water or ice on top of or next to the full locker.”
(2016 from the website) In Grand Teton you must store all food/toiletries and empty coolers as well as “cookware (clean or dirty), stoves and grills” in the bear box.
The boxes are dark metal and can build up heat inside, melting your ice faster. If you cover the box with something reflective, like the silver tablecloth yardage below, you can save money on ice.
ALL MODELS are metal and are noisy when opened or shut. Unless you are careful you can wake up your neighbors who want to sleep earlier or later than you.
Yosemite bear-proof food locker latching systems has pictures of how to properly latch a bear box.
Don’t believe anyone who tells you that the bears in Yosemite really don’t break into vehicles. For statistics go to:

A good way to wake up the whole campground is to set your car alarm. Then if a curious animal or clumsy person bumps the vehicle at night you’ve succeeded. (a car alarm won’t keep bears out of your vehicle).
Tent walls are thin. You can wake up everybody in the vicinity when you want to get into your car and you use the keyless (remote) door opener and the car makes the usual loud beep. People don’t think to just use the key to open the door or don’t know that if you look in the owner’s manual you can find a way to disable the beep.

Most Yosemite campsite models measure 35″ deep x 43″ wide x 28″ tall, some are 33″ deep x 45″ wide x 18″ tall, according to the the Yosemite website.
The Half Dome Village website said: “Your Half Dome Village cabin comes with one locker measuring:
35.5″W x 20.5″D x 23″ H (Small Tent Cabins)
47.5″W x 20.5″D x 23″ H (Large Tent Cabins)
Guests who don’t comply with our food storage policies may receive a fine up to $5,000.00 and be removed from the Park. Vehicles used for food storage may be impounded.”
The latest info on lockers sizes is at: https://www.nps.gov/yose/planyourvisit/lockers.htm
Metal bear-proof food storage boxes in Sequoia and Kings Canyon National Park campgrounds vary from 47″ long x 17″ deep x 17-3/4″ high to 47″ long x 34″ deep x 28″ high to 47-3/4″ long x 34″ deep x 22″ high or 48″ long x 34″ deep x 28″ high.
Some California State Parks have campsite food storage lockers. The ones we photographed at Sugar Pine Point State Park were 22 inches tall inside and 20 1/2 tall at the opening. They had two small corner posts at the back inside, so the width of 4 feet is minus a little at the back and the depth (front to back) we measured of 31 1/2 inches is from the front of the box to the corner post.
These are opened by putting your fingers into a space on the front and pushing up on the latch. If you push up too far the latch will not open.
We recommend bringing a good tent that will not leak rather than sleeping in a bear box.
(These ladies just posed for this photo, they actually slept in a tent.)
First-timer’s instructions has instructions for beginning snow campers for the De Anza College Outdoor Club winter trip, including info on the logistics of where to pitch your tent, dealing with iced car door locks, staying warm and comfy overnight while winter camping and more. Experienced people will probably pick up a few useful ideas.
