Choosing the Right Cooler
Consider the cooler size
Choosing the right size cooler is crucial when it comes to keeping your food and drinks chilled during camping trips. It’s important to think about how many people will be using the cooler and for how long. If you’re going on a short camping trip with just a few friends, a smaller cooler may suffice. However, for longer trips or larger groups, it’s best to opt for a larger cooler that can accommodate all your food and drinks.
Look for a well-insulated cooler
When it comes to keeping your food cold, insulation is key. Look for coolers that are specifically designed for ice retention and have thick insulation walls. Brands like Yeti and Coleman are known for their high-quality, well-insulated coolers that can keep ice frozen for days. Insulation helps to prevent the outside temperature from affecting the temperature inside the cooler, ensuring that your food stays fresh and cold.
Opt for a cooler with a tight seal
A tight seal is essential to prevent any cold air from escaping and warm air from entering the cooler. This is especially important when using dry ice, as it sublimates (turns from solid to gas) at a much faster rate than regular ice. Check that the cooler you choose has a reliable and secure latch or zipper system to ensure a tight seal. The brand Pelican is known for their coolers with reliable seals that keep the cold air locked in.
Check for durability
Camping trips can be rough and rugged, so it’s important to choose a cooler that can withstand the elements and any potential bumps along the way. Look for coolers made from sturdy materials like rotomolded plastic or stainless steel. These materials are durable and can withstand the rigors of camping. Brands like RTIC and Igloo are known for their durable coolers that can handle even the toughest camping adventures.
Choose a cooler with a drain plug
Having a drain plug in your cooler makes it much easier to clean and empty out any melted ice or water.

Look for coolers that have a convenient drain plug that allows you to easily remove any liquid without tilting the cooler or making a mess. The brand YETI offers coolers with durable drain plugs that make cleaning a breeze.
Understanding Dry Ice
What is dry ice?
Dry ice is the solid form of carbon dioxide. It is extremely cold, with a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). Dry ice gets its name because it doesn’t melt like regular ice; instead, it sublimates directly from a solid to a gas. This makes dry ice an excellent choice for keeping items cold without the mess of melting ice.
How does dry ice work?
Dry ice works by absorbing heat from its surroundings, causing it to sublimate into carbon dioxide gas. When placed in a cooler, dry ice cools the surrounding air and keeps the temperature inside the cooler at a much lower level than regular ice. This makes it ideal for preserving perishable items and keeping food and drinks cold during camping trips.
Safety precautions when handling dry ice
While dry ice can be a useful tool for keeping your cooler cold, it’s important to handle it with care. Dry ice is extremely cold and can cause frostbite if it comes into direct contact with your skin. Always use gloves or tongs when handling dry ice. Additionally, never store dry ice in an airtight container, as the buildup of carbon dioxide gas can cause it to explode. Always ensure proper ventilation when using or storing dry ice.
Purchasing and Transporting Dry Ice
Determine the amount of dry ice needed
To determine the amount of dry ice you will need for your camping trip, consider the size of your cooler and the length of time you need to keep it cold. As a general rule, you will need about 10 to 20 pounds of dry ice per 24-hour period for a medium-sized cooler. However, it’s always better to have too much dry ice than too little, as it will help maintain the cold temperature inside the cooler for longer.
Find a local supplier
Dry ice is not readily available at all grocery stores, so it’s important to find a local supplier that carries it. Many large grocery store chains, such as Safeway or Kroger, have dry ice available for purchase. Alternatively, you can use online directories or search engines to find dedicated dry ice suppliers in your area. It’s recommended to call ahead and confirm their availability and pricing before making the trip.
Package dry ice properly
When purchasing dry ice, it’s important to package it properly to ensure it stays frozen during transportation. Use a sturdy cooler or insulated bag specifically designed for transporting dry ice. Place the dry ice inside the cooler or bag, making sure it is properly sealed to prevent any gas from escaping. Remember, gas buildup can cause the container to burst, so it’s crucial to leave some ventilation for the carbon dioxide to escape.
Insulate dry ice during transportation
To maximize the effectiveness of dry ice, it’s essential to insulate it during transportation. Place newspaper or cardboard on top of the dry ice to provide an additional insulation layer. This layer helps to slow down the rate of sublimation and keeps the dry ice frozen for longer. Make sure the cooler or bag containing the dry ice is secured in your vehicle to prevent any spills or accidents during the journey.
Preparing the Cooler
Clean the cooler before use
Before using your cooler for camping, it’s important to clean it thoroughly to remove any dirt or bacteria that may be present.

Allow the cooler to air dry completely before proceeding to the next step.
Allow the cooler to dry completely
After cleaning, ensure that the cooler is completely dry before adding any ice or dry ice. Moisture can cause the dry ice to sublimate more quickly, reducing its effectiveness. Leave the cooler in a well-ventilated area or use a towel to dry any remaining moisture. It’s best to leave the cooler overnight to ensure it is thoroughly dry before adding any ice or dry ice.
Add a layer of regular ice
To provide an additional cooling layer, add a layer of regular ice to the bottom of the cooler before adding the dry ice. Regular ice will help maintain the cold temperature and can act as a buffer between the dry ice and the items you are storing. It also helps to keep perishable items colder for longer, as dry ice tends to be too cold for direct contact with food.
Place a protective layer between dry ice and food
To prevent freezing or excessive cooling of your food items, it’s important to create a protective layer between the dry ice and the food. Use cardboard or a thick towel to separate the dry ice from the items you want to keep cold. This barrier will help regulate the temperature and prevent direct contact between the extremely cold dry ice and the food, reducing the risk of freezing.
Arrange food items strategically
When packing your cooler, it’s important to strategically arrange your food items to optimize the cooling efficiency. Place the items that need to be kept the coldest, such as raw meats or dairy products, at the bottom of the cooler where the dry ice will be located. This ensures that these perishable items stay at the lowest temperature. Place less perishable items, such as fruits or vegetables, towards the top of the cooler.
Using Dry Ice Effectively
Handle dry ice with care
Dry ice is extremely cold and can cause frostbite if it comes into direct contact with your skin. Always wear protective gloves or use tongs when handling dry ice.
