Heading out on a camping trip and wondering about your cooler options? You might be asking yourself, is dry ice good for camping? It can be a fantastic tool, but it’s very different from regular ice. Using it correctly can keep your food frozen for days, while a simple mistake can ruin your trip. This guide will walk you through everything you need to know to use it safely and effectively.
Is Dry Ice Good For Camping
The short answer is yes, but with major caveats. Dry ice is solid carbon dioxide (CO2) at -109.3°F (-78.5°C). It doesn’t melt into a liquid; it sublimates, turning directly from a solid into a gas. This unique property is what makes it so powerful for camping, but also introduces specific risks you must understand.
Key Advantages of Using Dry Ice for Camping
Why would a camper choose dry ice over regular ice or frozen gel packs? The benefits are significant for certain types of trips.
- Extreme Cold and Longevity: Dry ice is much, much colder than water ice. A properly packed cooler can stay cold for 2-3 days or even longer, compared to 1 day with regular ice.
- No Water Mess: Since it sublimates, there’s no pool of meltwater to soak your food, make a mess, or require draining.
- Space Efficiency: It takes up less physical space than the equivalent amount of water ice, freeing up room for more food and drinks.
- Ideal for Long Trips or Group Camping: For expeditions lasting multiple days or for feeding a large group, it’s often the most reliable way to keep meat and perishables safely frozen.
Important Risks and Safety Precautions
You cannot use dry ice casually. Ignoring safety can lead to dangerous situations. Always follow these rules.
- Severe Frostbite Hazard: Dry ice can freeze your skin on contact in seconds. Always handle it with thick, insulated gloves (like leather or heavy cloth). Never use bare hands or thin plastic gloves.
- Ventilation is Critical: As dry ice sublimates, it releases carbon dioxide gas. In a small, enclosed space like a car, tent, or camper, this gas can displace oxygen and cause suffocation. Never store a cooler with dry ice in your sleeping area or a closed vehicle while you’re sleeping.
- Use the Right Cooler: Do not use an airtight, pressurized cooler. The gas build-up from sublimation can cause an explosion. Your cooler must have a venting lid or you must leave the drain plug open to allow gas to escape.
- Keep it Away from Children and Pets: Store your cooler in a secure location where curious hands and paws cannot access it.
How to Buy and Transport Dry Ice
Finding dry ice is easier than you think. Many large grocery stores, warehouse clubs (like Costco or Sam’s Club), and some ice suppliers carry it. Call ahead to check availability.
- Buy Last: Pick up your dry ice as the final errand before hitting the road. It begins sublimating immediately, even in a freezer.
- Transport Safely: Place the dry ice in an insulated cooler for the car ride. Do not put it in an airtight container or the trunk without ventilation. Crack your car windows open to ensure fresh air circulation.
- How Much to Buy: A general rule is 10-15 pounds of dry ice to keep a full, 50-quart cooler cold for 24 hours. For longer trips, you may need to plan for a mid-trip resupply.
Step-by-Step Guide to Packing Your Cooler with Dry Ice
Packing order is crucial for efficiency and safety. Doing it wrong can lead to frozen lettuce and warm steak.
- Pre-Chill Everything: Start with a cold cooler. Chill it overnight if possible. Pre-freeze all your food and drinks that you intend to keep frozen. Use regular ice packs or frozen water bottles for items you just want refrigerated.
- Create a Bottom Layer: Place a piece of cardboard or a towel at the bottom of the cooler. This insulates the dry ice from direct contact with the cooler’s plastic, which can become brittle and crack.
- Add the Dry Ice: Wearing your gloves, place the blocks or pellets of dry ice on top of the cardboard. It’s usually best to place it on one side or at the bottom, not directly in the middle of everything.
- Add Another Insulating Layer: Cover the dry ice with another piece of cardboard, a thick towel, or several layers of newspaper. This creates a barrier between the extreme cold of the dry ice and your food.
- Pack Strategically: Place items you want to keep rock-solid frozen (like raw meat, frozen pre-made meals) directly on or next to the insulated barrier over the dry ice. Place items you want just refrigerated (cheese, yogurt, fruit, drinks) further away, at the top of the cooler.
- Fill Air Gaps: Use towels, crumpled paper, or even extra clothing to fill any empty spaces. A full cooler stays cold longer than one with lots of air.
- Close the Lid and Vent: Secure the lid. Ensure the drain plug is open or the lid is slightly vented to allow CO2 gas to escape.
What Foods Work Best (and What Doesn’t)
Dry ice is not ideal for every camping food. Here’s a quick breakdown.
- Great Choices: Raw meats, frozen soups or stews, pre-cooked frozen meals, ice cream (a real camping luxury!), and large blocks of cheese you plan to use later in the trip.
- Use Caution: Vegetables and fruits with high water content (lettuce, tomatoes, berries) can freeze and become mushy if placed to close to the dry ice. Keep them in the top layer.
- Bad Ideas: Carbonated beverages in sealed cans or bottles. The extreme cold from dry ice can cause them to explode. It’s also overkill for a short weekend trip where regular ice is sufficient.
Pro Tips for Managing Your Cooler on the Trip
- Limit how often you open the cooler. Every time you open it, cold gas escapes and warm air rushes in. Plan your meals to minimize rummaging.
- If you need to add regular ice for drinks, consider useing a separate, smaller cooler. This keeps your main food cooler sealed and efficient.
- Monitor the remaining dry ice. You’ll be able to see it shrink. Plan your meal schedule so that items requiring the most cold are eaten first.
Disposing of Dry Ice Safely
Never just leave dry ice in your cooler or throw it in the trash, sink, or lake. At the end of your trip, let any leftover dry ice sublimate in a well-ventilated outdoor area, away from people and pets. Simply leave the cooler open outside until it’s completely gone. Never seal it in a container for disposal.
When to Stick with Regular Ice
Dry ice isn’t always the best answer. Choose regular ice or reusable gel packs if:
- Your trip is just 1-2 nights.
- You’re car-camping with easy access to buy more ice.
- You’re backpacking or portaging (it’s too heavy and hazardous).
- The idea of handling a potential hazardous material stresses you out.
- You’re camping with young kids and are worried about the safety risks.
Frequently Asked Questions (FAQ)
How long will dry ice last in my camping cooler?
It depends on the quality of your cooler, the amount of dry ice, how full the cooler is, and how often you open it. Generally, 10-15 pounds in a good quality cooler will last 24-36 hours. With excellent prep and a high-end cooler, you might get 2-3 days.
Can I put dry ice in a plastic cooler?
Yes, most plastic coolers are fine. The key is to avoid an airtight one. Place cardboard or a towel between the dry ice and the cooler’s bottom to prevent the plastic from becoming to brittle and cracking from the extreme cold.
Is it safe to put dry ice in a Yeti or Rtic cooler?
Yes, these rotomolded coolers are excellent for use with dry ice because of their superior insulation. Remember to leave the drain plug open to vent the carbon dioxide gas. Their tight seals make venting even more important.
Can dry ice make my food taste funny?
If packaged properly, no. Dry ice is pure carbon dioxide, which is odorless and tasteless. If your food isn’t wrapped tightly (like in a ziplock or sealed container), the CO2 gas can sometimes get absorbed and create a slight fizzy or off taste, especially in porous foods. Good packaging prevents this.
What should I do if I accidentally touch dry ice?
If you experience a brief touch, it will feel like a very intense burn. Remove your skin from the ice immediately. Run the affected area under lukewarm (not hot) water, just as you would treat a frostbite injury. Seek medical attention if blistering occurs or the pain is severe.
Can I use dry ice to chill my drinks quickly?
Technically yes, but it’s dangerous and not recommended. Placing dry ice directly in a drink can cause internal frostbite if ingested. It can also cause sealed drink containers to explode. For quick chilling, surround drinks with regular ice or cold water instead.
Final Verdict: Is It Worth It?
So, is dry ice good for camping? For the right trip, absolutely. It’s a game-changer for extended backcountry car camping, large group gatherings, or any situation where reliable, long-lasting freezing power is needed. The benefits of no mess and incredible cooling time are hard to beat.
However, it demands respect. The safety precautions are non-negotiable. For a simple weekend trip to a local campground, regular ice is simpler, safer, and perfectly adequate. Weigh the pros and cons for your specific adventure. If you decide to use it, follow the steps outlined here closely. Proper handling and packing turn dry ice from a scary chemical into the most reliable camping tool in your cooler. With a little knowledge and caution, you can keep your food safer and your drinks colder all trip long.
