Don’t let the summer heat get you down. We share our tips and tricks on how to pack a cooler for camping so your food and drinks stay colder, longer.

Tips for how to pack a cooler for camping

“How hard can it be? Just put food in a cooler and throw ice on top of it, right?”

This is how we use to think about packing our cooler. The truth is we didn’t really give it much thought. But after a critical miscalculation left us eating questionably refrigerated food and ultimately scrambling to locate more ice, we decided it was time to get serious about our cooler.

Since then we’ve learned a lot. After doing a bunch of research and trying out a couple of techniques, we’ve compiled some best practices for packing a cooler. So before the summer camping season hits, take a moment and learn how to pack your cooler like a pro.

If you have any thoughts or tips that you use to pack your cooler, let us know down in the comments. We’re always looking to improve our technique.

Selecting a Cooler

Upgrade Your Cooler – Cooler insulation has improved dramatically over the past couple years with brands like Yeti, Pelican, Orion, and even Cabelas, putting out some really incredible products. We’re talking rotomolded coolers with insulation at least 2” thick. After years of using a $20 Rubbermaid cooler, we upgraded to a Yeti Tundra 35. While we haven’t tested every cooler on the market, our Yeti has completely exceeded all of our expectations.

Two Cooler System – Depending on your group size and your budget there’s a strong argument to be made for having one cooler specifically for food and one cooler specifically for beer & other drinks. The drink cooler is going to be opened a lot more frequently and will, therefore, warm more rapidly. Digging underneath your food to find a cold beer at the bottom is not only a hassle but a major waste of energy. So if you can afford it, a second cooler can really help your perishable food items stay colder and safer for longer.

Cooler Prep (Day Before)

Bring Your Cooler Inside – If you store your cooler in a hot attic, shed, or garage, bring it inside at least a day before your trip. You want the cooler’s core temperature to be as cold as possible.

Clean Thoroughly – Chances when you got back from your last trip you didn’t do a great job cleaning the cooler. Take a moment now wash it down with a disinfectant spray. One of the best ways to increase food safety is to start with a squeaky clean cooler.

Pre-Chill – To really lower the core temperature of your cooler, fill it with cold tap water (hose water) and add a bag or two of “sacrificial ice” at least 12 hours before your trip. Dump this ice water right before you pack your cooler.

Camp Cooler Tips: Prep food the day before packing a camp cooler

Food Prep (Day Before)

Prep Food – To save space, you will want to prep as much of your food at home. Pre-chop your veggies and make the marinade ahead of time. Portion out condiments into smaller vessels if you don’t need the whole bottle. The less space the food takes up in the cooler, the more room there is for ice.

Remove Excess Packaging – Store packaging can take up a lot of extra space, so remove what you can. There’s no need to bring a whole carton of eggs if you only need 6 and you definitely don’t need the cardboard caddy that comes with a six pack of beer.

Transfer to leak-proof containers – Another reason to remove store packaging is because it’s usually not resealable. Assume everything in your cooler is going to get wet (because it will). So unless you want your half opened packet of hot dogs floating next to your beer cans, we suggest transferring everything into reusable, leak-proof containers.

Freeze – For longer trips, you will want to freeze as much of your food as possible. Obviously, don’t freeze the food you’ll need to eat on the first night. But if you plan on having steak on the last night of your trip, freeze it. You can also freeze water bottles, but be sure to dump ¼ of the liquid to allow for it to expand.

Refrigerate – Everything that is not being frozen should be refrigerated before being packed. That includes resealable food containers. Really nothing should go into the cooler that’s at room temperature, otherwise, you waste your ice cooling things down instead of just keeping cold things cold.

Ice Selection

Block Ice & Freezer Packs – The best ice foundation is either block ice or large reusable freezer packs. These solid blocks of ice take much longer to melt than ice cubes. Place these at the bottom of your cooler and build on top of them.

Don’t have reusable freezer packs? Try freezing a bottle waters (singles or gallons) with about 1/4 of the water removed from inside so the ice can expand. Lay horizontally inside your freezer.

Ice Cubes – While ice cubes melt faster than block ice, they do a great job of filling in the cracks. So fill the spaces in between your food items with ice cubes.

Dry Ice – For extended trips, consider using dry ice. Dry is extremely cold and will freeze anything it touches (including your fingers) so be very cautious with how you handle it. For more information about using dry ice, Yeti has a good article about it.

Packing Your Cooler

Last Thing in the Car – Wait until you’re about to get in the car before you start packing your cooler. This should be the last thing you do before you walk out the door.

Block Ice on Bottom – Begin with a layer of block ice on the bottom, then back in food items in reverse order. Starting with the last day’s food on the bottom, work your way up so the first day’s food is sitting on top.

Ice Cubes In Between – Air is the enemy. Large pockets of air inside your cooler will accelerate ice melt. So fill up as much of that space as you can with ice cubes.

This Side Up – Play it safe and assume everything might leak. When placing containers with liquid, make sure they are placed vertically.

Meal Categories – Pack breakfast foods to the left and dinner foods to the right. That way you’re not searching all over for your ingredients when it’s time to cook.

Map it Out – If you have a have a particularly large cooler, it helps to make a quick cooler map so you know where things are located (minimizing the time your cooler is left open while you search for what you’re looking for).

How to make ice last longer in a cooler

Best Practices

Transportation – When loading your vehicle, keep the cooler inside the car with you. Avoid putting it in a hot trunk where it is apt to overheat.

Keep it Shaded – At the campsite, place your cooler under a picnic table or somewhere else shaded. The sun is a heat source and you’ll want to avoid direct sunlight as much as possible. You can place a wet towel over the top of it to help insulate it further.

Keep it Closed – The single biggest factor in how long the ice in your cooler will last is how often it is opened and exposed to outside temperatures. Keeping it closed keeps it cold.

Do Not Drain Meltwater – While it might go against conventional wisdom, it has been scientifically proven that it is better to leave the meltwater in the cooler than to drain it.

Cooler Add-ons

Knowledge is Key – If you really want to know what’s going on inside your cooler, consider buying a small food thermometer and attach it inside. That way you’ll know at a glance whether food is being stored safely (temp below 40 F).

Reflection – Use reflective paneling on your cooler to help prevent it from heating up in direct sunlight.

  1. I like to use zip lock freezer bags, rather than containers for frozen food. Think tamale pie filling. It can either lay flat or stand up along a wall. My goal is to not pack any air, ever. Then you don’t have to figure out where there is room for the empty container. The empty bag becomes your trash bag for the night, or a place to store leftovers.
    Also, found something on Pinterest for tiny amounts. Use plastic drinking straws for spices, toothpaste (single use) and such. Pinch end with needle nose pliers, use flame to seal, fill, seal other end, and label. Fat shake straws hold more. Have not tried it yet, but sounds good.

    1. These are great suggestions! Thank you so much for sharing. Agreed with trying to pack a little air as possible. Ziplock bags would definitely offer more versatility in stacking/organizing. We’ll have to give it a try.

    2. The bags sound like a great idea. I don’t like single use items but for camping, sometimes I make exceptions. The leftover plan is great! I reuse the tupperware I bring for this but if there are no leftovers, I have an empty container to find a place for. The trash bag becomes the perfect re-use option. I do some backpacking and they have some great, very small items for spices. Some have several sections for different varieties. I use those, but the straw is good if you have some to make use of. Another item I’ve eliminated from my home.

  2. We use wide-mouth plastic containers, preferably squarish in shape (the kind in which rice blends or nuts come in), to make ice blocks before we leave – the fresh water can be transferred into our water jug as it melts; the containers can then be easily refilled with ice cubes along the way, keeping the melt water off the food in the cooler. We also use large freezer bags to hold pre-frozen homemade chili, pasta sauce, beef stew, butter chicken, pulled pork, etc. for the same reason as Linda does. We’ve had our coolers (one large and one medium-sized) for years, thanks for the tip about recent improvements – we’ll be looking into that.

  3. And if/when we take eggs, we crack them into zip lock bags. 3 per baggie for me, 2 per baggie for her. Leave the shells at home. Pour into the hot pan at the campsite/Basecamp… shredded cheese, onions and green peppers and mushrooms added to a bag or two with the eggs for an “instant omelet” meal.

    1. I prep our scrambled eggs and freeze. Lightly beat the number of eggs, put in a bag/container then freeze. It works great! We’ve also tried omelets in a bag, prep everything at home in a freezer ziploc, freeze(or not), at campsite boil some water and place the omelet bag in the water approx 10min. Quick clean up and the hot water is ready to do dishes.

      1. Make sure to leave out the mushrooms till you’re at the campsite! A bag omelet left with mushrooms sitting in it will turn a pukish gray… Bleh.

  4. How to pack a cooler like a pro? A cooler is a MUST have in every camping trip. You must select the perfect cooler base on the number of days you’ll go camping, the things that you will bring, the activities that you plan to do, and so much more.

  5. For this tip there’s no substitute. It’s not just about buying a rotomolded cooler but knowing how to properly pack your cooler. That’s what matters most!

  6. Helpful tips. Thanks for sharing. I think YETI coolers are best for keeping foods for longer time. I am using one and it is really great.

    1. YETI (and really any of those roto-molded high-end coolers) are in a league of their own. WAY better than the old school coolers we used to use.

  7. Antonia G Kitto says:

    i love the idea of ziplock bags and straws, but one of my goals this year has been to majorly reduce my use of single use plastic. straws especially are having a horrible impact on our environment. i like the tiny tupaware for spices, and i bring travel siz toothpaste. definitely going to make my own block ice now! love all the suggestions! <3

  8. I like how you mentioned to pack your cooler right before getting in the car. I imagine this is because it will help the food stay fresh for a longer period of time. My friend absolutely loves to go hiking, so I think she’d like to go for a picnic in the canyon. I’ll definitely use these tips when I pack my cooler!

  9. Stephanie says:

    I lay clean dish towel on top of everything before I close the lid. It reduces the amount of air around the food and keeps everything colder for longer. I have a standard cooler and found that the ice can last up to two days with this method.

  11. Question about where to store the cooler: When parked and the AC isn’t on for long periods of time, is outside the car better than the inside? I.e. driving to a trail head where you don’t have a camp site to leave the cooler. It seems like it would be but I’m wondering if it makes that big of a difference. Just got a Yeti 35 for Florida and Southwest desert trips and tested it in the car. Ice lasted for 2 days in 97 and 94 degree weather. Surely outside of the car would be better? I’ve been Googling it with no results. Thanks!

    1. Hmm. I think it’s really going to be dependant on the difference between the ambient outside temperature vs the inside temperature of the car. Outside of the car and in the shade is ideally where you want it to be, but that might not always be practical. A parked car (not running A/C) functions like a greenhouse and always is hotter inside than the outside air temperature.

  12. Thanks a lot for sharing such great tips on packing a cooler perfectly.

  13. Get yourself a vacuum sealer and seal then freeze the meat in meal size portions, it will last longer once it has defrosted. I use those large zippable dog food bags, well washed obviously, to hold the frozen meat and ice. This stops any contamination of other food if you meat packaging leaks. Freeze large water bottles to keep the rest cool.

    1. We should really pick up a vacuum sealer. They seem like they would be super versatile and perfect for freeze food. We agree with you whole-heartedly. If it can be frozen beforehand, it should be.

  14. M Nielsen says:

    I like the idea of reusable ice packs, but seems to only make sense for a short term trip. Otherwise, how would you re-freeze them when on the road? I’m just a casual car camper, and really appreciate your tips for improving my skills. Thanks!

    1. True, the reusable ice packs are only good if you can refreeze them. If you’re on an extended trip, then picking up ice periodically is going to become necessary.

  15. We tend to go away as a family of 6 for a week at a time.

    I use a huge cool box and freeze almost everything. I buy milk in smaller containers, and also fruit juice in litre bottles – these are all pre-frozen apart from the one for the first night. Pancake batter is made at home from scratch and frozen (in 2 pint milk containers – one for each day). I pack my cool box so that everything chilled /frozen for breakfast and lunch are packed into one bag or box along with milk and a bottle of juice. Dinner and Supper are then packed into another bag. So if Im going for a week I have 14 bags in the cool box and a emergency backup bag.

    I only need to open my cool box twice a day to get that half days rations out – which is all together in one outer bag. Once the half days stuff is out I use a homemade bubblewrap / foil insulation bag to keep it cool.

    No cool packs, no ice and my food is always cold on day 7 – sometimes still frozen.

    I tend to keep small bottles of milk, fruit juice and pancake batter in the freezer just in case of a last minute camping trip. Also when I make a meal or sauce at home that translates to campfire food I double up and freeze half (i.e. pasta sauce)

    1. Thanks for sharing. Freezing ingredients ahead of time is definitely the way to go and it sounds like you have a fantastic system going. Minimizing how often you open the cooler is also critical, so that’s fantastic that you can pair it down to opening it up just two times a day.

  16. sarah williams says:

    I’m finding it tough to find ice block to fit at the bottom of my cooler . any suggestions? Do i need to buy a block and cut it myself?

    1. You can always make a block of ice yourself. Clear out some space in your freezer, get a high-sided baking pan that fits inside your cooler, and then freeze the water yourself. It does take a bit of foresight but it saves you instead of buying ice from the store.

  17. I have been camping for over 15 years, and one of my favorite cooler tricks a few days ahead, is to make ice packs in several different sized zip-lock bags. Gallon sized fit nicely and flat along the bottom of the cooler, and the smaller Quart, sandwich or even snack sizes, fit in between items very easily, along with freezing some of the food, my cooler stays cold for days!!!

    1. Good tip! Buying ice can be expensive, but with a little foresight, you can make lots of the stuff yourself. And in more useful sizes. Good trick with freezing them in gallon freezer bags.

  18. Christy Lundy says:

    Wish I’d read this before our trip this weekend! Next time my cooler packing will be a little more methodical!

  19. I love my Yeti cooler and it also has exceeded my expectations. The pre cooling is so important. Thanks for the great ideas. You’d think with tons of experience would come this very useful knowledge, but I am still learning. The organizing by sides is a fantastic plan. One of my biggest issues is the chaos in the cooler. My next trip will be much more structured in the cooler department:) Thanks for the great info!

    1. Pre-cooling and freezing food ahead of time has made a big difference for us. It’s also hard to give up so much of the interior space to ice, but maintaining a proper food to ice ratio is critical. There is always room for improvements!

  20. For those who drink boxed wine, or know someone who does, the bladders inside those boxes make really good containers for water, which can be frozen and used in your cooler. They’re a pretty good size, too.

  21. Marti Furman says:

    Great suggestions! We have a small trailer with refrig. And supplement with a cooler. The cooler is usually the “freezer” with dry ice for food towards the end of the journey.

  22. Rebecca Louise Rendon says:

    Thanks for all the great tips. Learned a lot today, the ice cream salt goes on the top of the ice, no gaps of air,wrap dry ice in several layers if newspaper & top placement is prefer but bottom is ok too.block ice is best but cubes are great to fill spots of openness, pack backwards from last day to first day,breakfast to left dinner to the right, first layer if food last days frozen foods,add another layer of ice then snacks and drink, including cleaned ice chest keep all items chilled, prepped , package free,limit times cooler is open keep in cool shaded place/wrap in a sleeping bag.

  23. Carol McD says:

    Great tips. Here are a few more. Freeze block ice in large, square tupperware style containers so that when the ice melts, it does not leak. The melted water can be used for drinking in a pinch.

    As far as the fill in ice- we either use frozen small water bottles or place ice cubes in quart sized heavy duty zip top plastic bags. Again, no leakage and the bags may come in handy for produce or leftover storage.

    Last- lay a towel on top of the food before closing the lid. That way you only have to pull up a corner or two and it inhibits warm air from entering your cooler. Similar idea to the 2 cooler system- one for drinks, one for food. Keep the food as cold as possible.

    We’ve been camping for over 50 years. Your website has great tips and ideas for all levels of camping experience. great recipes too. 🙂

    1. Thank you so much for your support! And for the extra cooler tips as well! We are definitely going to try out the cool towel trick this summer! Thank you for sharing.

  24. Patti Lee says:

    we like to use Milk cartons with screw top lids to freeze our water for block of ice. Works great, doing same by not filling to top of container so doesn’t overflow.
    We have been using a Yeti cooler for 3yrs now, and is the best thing ever. Is very heavy though so when we load the cooler,just before we leave, hubby loads in back of truck and I fill it there. Saves on your back…

  25. Very good article! I think I’ve tried everything to get the max. out of my cooler, in terms of ice retention, and packing it RIGHT is probably the most impact thing on the list of tips to maximize cooler ice life. When you pack it right (e.g. place block ice at the bottom as you wrote), not only you’re going to increase the ice retention but you’ll also spend much less time with the lid opened, and you’ll likely be able to pack more food/drinks inside.

    My other favorite hack is to add some rock salt on the top of ice – it helps the ice in your cooler last longer because it lowers the freezing point.

    Hope it helps!

    1. Happy to hear you approve of the article! Thank you for the suggestion about the rock salt. We haven’t played around with it at all, but we’d love to start trying it out.

  26. Miranda Huck says:

    Absolutely LOVING your site!
    Thank you!!! ????????????

  27. Jenny Gayden says:

    I bought lots varity meats at the store. And bought cooler put ice and made sure there was plenty of ice for trip home 12hrs. Juices got mixed from beef steak to chicken legs, to pork. Never got above 40. steak was discolored to. Ice melted. Are the meats still ok, if rinsed amd stored in freezer right when got home?

    1. Yikes. So you’re definitely entering into uncharted territory food safety-wise. If you’re confident everything stayed below 40 F, rinse thoroughly with water at home, repackage into resealable containers and then placed in the freezer, you should be okay. However, I would be sure to cook this meat to USDA recommendations. 145F for steaks, 145F for pork, 165F for chicken. We’re not food safety experts, but that’s what we would do.

  28. MotherNature from Massachusetts says:

    Great information. Thank you! for my old-fashioned plastic coolers I have made insulation blankets using reflective material that comes in a roll and duct tape. It adds 2-3 days to my cooler’s ability to keep my items cold, my ice frozen, and the melted ice water very cold. They were quite simple to make and only take about 2 hours.
    I’d love to show you my photos if you’re interested.
    Happy Camping.

  29. Sheila Resari says:

    Wow, I have learned so much reading this article and the comments! Planning to pack my new cooler (not rotomolded, but an upgrade from previous) w/DIY block ice (gallon milk jugs, tetra bricks) and add a crate for produce (no sog) and a thermometer to check temps. Excited to see how this works on our upcoming camping trip!
