This is a bit late and probably won't help you much on this go around.
My best advice is come prepared. We camp quite a lot and this always works well for me. I make it a priority in packing prep. I have a list I keep and check off to make sure I have all my keto stuff. Plan ahead and bring all your favorite keto snacks, dips and etc. Which is harder if you are tent camping and only have a cooler to keep things. We have an RV so we are cheaters. lol Of course I have 4 kids, too, and I will not take them tent camping again until they are older. Lesson learned. Man, can little kids make a person miserable in a tent, let me tell ya!

I bring pork rinds, make a dip, nuts, cheese, cut-up raw veggies with ranch. I bring generic Mio to flavor water and vodka if I get an adult bev craving. And if you have a sweet tooth, prepare some fat bombs ahead of time and bring them to whip out when the craving strikes. I'd think keto hot cocoa might me nice around the campfire, too, though I haven't fussed with that.

I only count carbs on camping trips and forget about worrying about calories. I do miss the smores...but I don't miss the 95lb I've lost on this WOE. So I've learned to be happy with the adjustments I've made in my life and be happy with the substitutions. Not obsessing over what I CAN'T have, but focusing on all the delicious keto things I have to choose from. Because we have SO MANY yummy choices.

I hope you enjoy your trip.

Pork rinds would be nice for backpacking 'cuz they're so lightweight, but they would get crushed easily too. Summer sausage-type stuff could be good. Also tinned fish of various varieties.

Oh, and jerky. Homemade is best!

When we camp I pack a ton of jerky, nuts or nut butters and coconut manna. Tanka bars are also great for camping. If you have a pop up camper and can keep things cold I would bring bacon...but then everyone will want to eat your bacon. If you're backpacking pork rinds take up too much precious pack space. Sometimes I make granola before we go. Nuts and seeds, coconut oil, vanilla and cinnamon tossed together and baked a bit makes a pretty good granola. Camping is also one of the times I allow myself more carbs. Usually larabars, after being keto the carbs feel like rocket fuel in the trail

I stick with macadamia nuts (over peanuts and almonds), even though they cost more. To me, they are the perfect carb/fat ratio. A very small portion is satisfying and sustaining. I worked an outdoor Ren Faire back in March and made it through the limited break days with macadamia nuts, cheese, salami, (in a cooler, obviously) and a normal meal at home. Started most days with some type of bullet proof tea or just crammed in as much fat as I could (beef sticks, hard cheese, nuts) before I left the house or on the way (scotch eggs hold up well in a cooler, hardboiled eggs might be good too...)... Pickles are another go to if I'm sweating a lot and need to drink a ton of water and still keep my sodium up. I think I even stashed some "frozen" fat bombs but didn't end up eating them...

@baconslave, I thought you'd say you pack Spam-a-lot while camping, lol.
