What to check first (do this before you drive out)

Before you even think about packing the car for a cold-weather camping trip, there are a few key things to sort out. It’s all about being prepared, not just for comfort, but for safety.

• Land manager / legality: Who actually owns or manages the land you’re heading to? Is it National Forest, BLM land, a State Park, or private? Each has its own set of rules. You need to know if dispersed camping is allowed, if permits are needed, and any specific regulations. A quick look at the agency’s website or a call to a local ranger station is your best bet. Don’t assume.

• Access/road conditions: How are you getting there? Is the road paved, gravel, or just a dirt track? Will your rig handle it? Think about tire clearance, 2WD vs. 4WD, and if recent rain or snow could have turned things into a mud bog or impassable snowdrift. Some forest roads get gnarly fast. I learned that lesson the hard way with a flat tire miles from anywhere.

• Fire restrictions + weather + wind: This is non-negotiable. Check current fire bans rigorously. A campfire is nice, but a wildfire is not. Look up the forecast, but also pay attention to wind. High winds can make even a small fire dangerous and can drastically lower the effective temperature. Don’t forget wind chill.

• Water plan + waste plan (Leave No Trace): Where will you get water, and how will you treat it? Don’t plan on finding a pristine mountain stream that’s safe to drink straight from. Pack in what you need or have a reliable filter/purifier. Equally important: pack out everything you pack in, including all trash and food scraps. Bury human waste properly, away from water sources.

• Safety (wildlife, distance to help, comms): What kind of critters share this space? Know how to store food properly to avoid unwanted visitors. How far is the nearest town or ranger station? Do you have cell service? If not, do you have a satellite communicator or a plan for emergencies? Let someone know your itinerary.

Step-by-step (field workflow)

Okay, you’ve done your homework. Now it’s time to get set up and make camp. This is where the rubber meets the road.

1. Arrive and assess the site.

• What to do: Drive to your intended camping area and do a quick visual sweep. Look for established spots or good places to set up that minimize impact.
• What “good” looks like: A clear, flat spot away from dead trees or potential hazards. You can see the lay of the land.
• Common mistake: Driving off-road to find a “better” spot. This damages vegetation and can get you stuck. Stick to existing tracks or pull-offs.

2. Set up shelter first.

• What to do: Get your tent or shelter pitched. This gives you a base and protection from the elements, even if it’s just sun or a light drizzle.
• What “good” looks like: A taut, well-staked tent or tarp. It’s secure and ready for whatever comes.
• Common mistake: Setting up a campfire or cooking area before the shelter is secure. Weather can change fast.

3. Organize your gear inside the shelter.

• What to do: Bring your sleeping bag, pad, and essentials inside. Unpack anything you’ll need immediately.
• What “good” looks like: Your sleeping area is ready and protected. You know where your headlamp and warm layers are.
• Common mistake: Leaving valuable or essential gear exposed outside overnight.

4. Establish your cooking/fire area (if permitted).

• What to do: If fires are allowed and conditions are safe, clear a ring or use an existing one. Set up your stove and cooking gear away from flammable materials.
• What “good” looks like: A safe, contained fire pit or a clean cooking setup. You have water and a shovel nearby.
• Common mistake: Not clearing enough space around the fire pit, or setting up too close to the tent.

5. Secure food and scented items.

• What to do: Use a bear canister, hang a bear bag, or store items in your vehicle (check local regulations for what’s best).
• What “good” looks like: Your food and anything with a scent (toothpaste, chapstick) is inaccessible to wildlife.
• Common mistake: Leaving food scraps or wrappers out, or storing food in your tent.

6. Gather water or prepare water treatment.

• What to do: Head to your water source with your filter, purification tablets, or containers.
• What “good” looks like: You have a good supply of clean drinking water for the evening and morning.
• Common mistake: Waiting until you’re thirsty to get water, or assuming a stream is safe to drink from.

7. Prepare for the evening.

• What to do: Start dinner, get your fire going (if applicable), and put on your warmer layers.
• What “good” looks like: You’re comfortably settled in, warm, and fed.
• Common mistake: Not putting on enough layers before you get cold.

8. Secure camp for the night.

• What to do: Double-check that the fire is completely out, all trash is secured, and food is put away.
• What “good” looks like: Your campsite is clean and safe, ready for you to sleep soundly.
• Common mistake: Leaving a fire smoldering or food accessible.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Ignoring fire restrictions	Fines, wildfire, destruction of habitat, injury or death.	Always check current fire bans <em>before</em> you leave. Have a backup plan for cooking (stove).
Not checking road conditions	Getting stuck, vehicle damage, long delays, needing a tow.	Research road status, know your vehicle’s capabilities, and have recovery gear if necessary.
Improper food storage	Attracting wildlife (bears, raccoons), damaged gear, potential encounters.	Use bear canisters, hang bear bags correctly, or store food in a vehicle as per local regulations. Never in your tent.
Leaving trash behind	Polluting the environment, harming wildlife, negative impacts on future visitors.	Pack it in, pack it out. Everything you bring, including food scraps and wrappers, must leave with you.
Not having a water plan	Dehydration, illness from contaminated water, needing to cut trip short.	Bring a filter/purifier or enough water. Treat all natural water sources before drinking.
Setting up camp in a hazardous spot	Falling branches, flash floods, unstable ground, uncomfortable sleep.	Look for level ground, avoid dead trees (“widowmakers”), and check for signs of flash flood potential.
Not letting anyone know your plans	Delayed rescue if something goes wrong, increased risk if you’re overdue.	Leave a detailed itinerary with a trusted friend or family member, including your route and expected return time.
Relying solely on cell service	Being unable to communicate in an emergency when service is lost.	Carry a satellite messenger or personal locator beacon (PLB) for areas without cell service.
Underestimating the cold	Hypothermia, discomfort, poor sleep, inability to function.	Pack appropriate layers, including base, mid, and outer layers. Bring a warm hat and gloves, even if the forecast looks mild.
Not knowing land ownership/rules	Trespassing, fines, confiscation of gear, being asked to leave.	Identify the managing agency (USFS, BLM, NPS, State Park) and check their specific regulations for the area.

Decision rules (simple if/then)

• If the forecast includes high winds, then plan to secure your tent extra well because strong gusts can easily damage or destroy it.
• If you see signs of bear activity (scat, tracks), then immediately double-check your food storage plan because bears are attracted to smells.
• If the road leading to your campsite is unpaved and looks rough, then consider if your vehicle has sufficient clearance and 4WD before proceeding because getting stuck is a major hassle.
• If you are camping in an area known for mosquitoes or ticks, then pack insect repellent and consider long sleeves/pants because disease transmission is a real risk.
• If there are any fire restrictions in place, then do not build a campfire because violating these rules can lead to severe penalties and environmental damage.
• If you are unsure about water sources, then err on the side of caution and bring all the water you’ll need because dehydration is a serious and fast-acting problem.
• If you plan to camp in a remote area, then ensure you have a reliable way to communicate in an emergency because cell service is often spotty or nonexistent.
• If temperatures are expected to drop significantly overnight, then pack extra warm layers, including a hat and gloves, because you lose heat rapidly from extremities.
• If you are unfamiliar with the area, then download offline maps or bring a physical map and compass because GPS can fail, and you don’t want to get lost.
• If you plan to hike any distance from your campsite, then bring a daypack with essentials (water, snacks, first-aid, extra layer) because you never know when a short hike might turn into a longer one.
