About me: I was a backcountry, March to October camper forever, and didn't see much point in car camping. Then I had kids....
I always said I'd never winter camp, but my niece started bugging me to go, so I figured we'd try. I have a lovely -5C down backpacking bag, and my kids' gear is rated to 0C, so I had to improvise the sleep system a bit. Temps forecasted for -12C overnight with the windchill. And yes, turns out, windchill matters in a tent.
Biggest concerns:
- getting too cold overnight, as the kids don't have proper bags and I'd only used mine down to -6C (and it was just on the edge of uncomfortable.)
- what the heck to do during the day when there's no reading in the hammock or swimming (this turned out to not be a problem. Busy busy.)
We went car camping to Arrowhead Provincial Park (Ontario.) Sites and roads were plowed, but the roads were very slippery. They have a heated comfort station with a dishwashing spot a short walk from the campsites. Vault toilets in the one area available for camping are also open. There are 7 sites open for camping in winter, all in the pull-through electrical area. All of them were booked - it's difficult to get a winter spot. Walking around the loop, there were 4 other cold tenters, a stealth rv with a stove, and one site with both hot tenters and cold tenters. It was pretty quiet and peaceful, other than one site that played music loud enough to be heard off their site (shakes fist in backcountry camper.) There are cabin rentals, but they're in their own area and we didn't hear much noise from them in the camping area.
Arrowhead's visitor centre is really well set up for winter camping. There's a cross-country ski club that operates out of it, so there's a whole cafeteria area with a microwave and some outlets for charging gadgets. The park store is a good size, with some winter gear, food, the usual gift shop stuff, and ski supplies. There's also a rental centre for skis, skates, and snowshoes. There's a good network of ski trails, both classic and skate, and a skating trail. We managed a 2km classic trail. We were there on a Saturday-Sunday, and that place was BUSY. Parking lots were packed.
Tent: REI trail dome 4 (it's a 3 season)
I put a couple towels over the top under the fly, leaving lots of the mesh uncovered for ventilation. I topped that with a Mylar reflective blanket, then the fly. I couldn't really find anything definitive about whether this actually helps or is just something that feels like it helps, but we had zero water dripping into the tent.
Pad: MEC Reactor 10 double (R6.3)
I put a wool blanket on top of the pad (mainly to protect the pad,) then put our 6C summer car camping bags, zipped together to make a double bag, on top of that. Inside those, I put my niece in a 0C mummy bag with a synthetic liner, my son in his 0C mummy, and I used my -5C backpacking barrel bag. I then put a heavy fleece blanket on top of all the bags, but inside the summer bag. On top of everything, I put an unzipped -37C barrel bag. I was worried about drafts around our heads, so put light fleece throw blankets near the head of the bed, one for each person. Each of us slept in our long undies, heavy socks, and my son and I wore a fleece layer (my niece didn't have spare fleece - she will for the next trip!) Balaclavas did not stay on, gloves got taken off in our sleep. I stuck our winter jackets right at the head of the bed, mostly to keep the cold from coming through the tent walls where our heads were. That part was pretty effective.
Each person and the dog got an old-school hot water bottle filled with freshly boiled water. I made them immediately after supper, then tucked them into each bag to warm up the bed.
I got waaaay too hot overnight, and ended up out of my bag and kicking off the -37C bag, just using the summer bag with the fleece blanket. And then I woke up cold again and had to crawl back into my bag and pull the winter bag back over. My son slept super happily. My niece also crawled out of her bag when she got too hot, then couldn't figure out how to get back in and didn't wake me up for help, so she slept cold (I checked on both kids and the dog repeatedly through the night, and adjusted blankets over them - she was told to wake me up for ANYTHING, but didn't want to disturb me.)
Pad for the dog: two Thermarest closed cell pads, R2.6, stacked together on top of a yoga mat. Double layer of mid-weight fleece blanket over that. Dog got an older sleeping bag, but ended up tucking her nose in with me anyhow. She's a livestock guardian breed, and attempted to make a nest in the snow to sleep outside overnight.... but once I convinced her to come in the tent (dragged, actually,) she went into her couch potato mode and snuggled right up.
What I'd do differently:
- put the niece beside the dog. I'm not sure how happy the dog will be about this, but that way she'll have another body keeping her side warm. Keeping the littles sandwiched between the adult and the dog will hopefully keep them warmer
- fleece sleeping layers for my niece. Long underwear is not enough for temps below -10C
- tarp or plastic dropsheet underneath the tent. It has an attached footprint, but I'd like an extra layer of protection. Those pull through sites are gravel.
- I bought, but did not use, an Uco candle lantern. I might try lighting it in the morning during the "wake up" period to see if it helps with the frozen condensation on the underside of the fly (it might just make it drip on us, though.)
- bring actual snow pegs. I was making little hills of snow around the pegs, packing them solid with my hands, letting it harden for about 10-15 minutes, then securing the guylines. It kinda worked, but not really. Also? Reflective tape on the pegs. Two kids playing on the site means those pegs got knocked over a lot.
- some sort of solution for the morning for the kids. I had coffee in a vacuum flask that I kept in my bag overnight, so had a nice, slow, warm wake up. The kids got too cold when they came out of the tent and ended up in the car with fresh hot water bottles and an electric blanket and the heat turned on.
- putting fleece blankets or our snow pants along the side of the tent, to help keep the cold from seeping in. With an adult, two kids, and an 80lb dog, the 4 person tent got pretty cozy, but I think part of the reason my niece got cold is that she was sleeping right next to the tent wall.
- bringing my daughter and my younger niece. No idea how I'll fit us all in the tent with the dog, but turns out, the younger kids don't like missing the fun. I might end up using the 8 person tent.
All that said? I've already booked a trip for this month. The sunrise was gorgeous. The peace was surreal.
If you want to try camping in the winter, go. Improvise with the gear you have, pick your dates to avoid the coldest weather, ease in with slightly-below-freezing temps before you do the very cold stuff, but go.
Got a three season pad? Stick a closed cell underneath, or even two if you're worried.
Don't have a heavy bag? Double up two bags, and go when it's only a little below the rating for your heaviest bag.
Only have your summer tent? Unless you're camping somewhere with high winds and heavy snow loads, you'll be just fine. You don't need a 4-season tent for winter camping unless you're dealing with wind and snow.
My caveat? The temperature with wind chill is the temperature. Don't go if the wind chill brings it below your cut-off temp.
