So, how do you stay clean when you live in the wild for weeks at a time? You don't. And that's kind of the point.
Spending time in the wild for days or even weeks means you're going to get dirty and that's okay. Getting comfortable with a little dirt is part of the magic of a long backpacking trip. But there's a difference between being dirty and being unhealthy.
Here's my hiking and camping hygiene kit, plus the outdoor hygiene approach I've worked out for anyone who wants to stay clean (enough) and protect the wild places we love. These are the tips I learned after doing a couple of long-distance hikes, like the Waitukubuli National Trail, and the most recent one: hiking 850 km across the Pyrenees on the GR11, and a few more living out of my pack, practicing natural trail hygiene the simple, natural way. And as well as from living full-time vanlife and sailinglife.
From experience comes awareness. From caring comes action.

Why is hygiene on the trail different?
Hiking and camping in the wild change your relationship with personal hygiene if you're used to having modern facilities. You won't have showers or sinks. Your water source might be a stream, and your “bathroom” involves pooping in the woods.
But that doesn't mean you can't stay healthy. It means redefining what “clean” looks like and understanding that good outdoor hygiene is about keeping yourself, your gear, and nature safe.
Hygiene on trail isn't about feeling super clean. It's about feeling healthy, fresh enough, and leaving the trail better than you found it. There's a big difference between being dirty and being unhealthy. We get dirt under our nails, mud on our face, and stains on our shirt. That's normal. I did not get sick on trail once, and I don't remember the last time I've actually been sick. I believe just being on a long-distance hike is one of the healthiest things you can do.
Personally, for me it isn't much different from my daily life. I live in a van with a watertank of only 25 liters. The ocean, streams or spray bottle is my shower. I must do something right.
Forget “clean.” Aim for healthy.
Wild camping and on trail, dirt under your nails, messy hair, and sweat are normal. You'll never stay spotless, and you shouldn't try.
The real goal is simple: avoid getting sick and leave no trace. We get sold this idea that you need to bring wipes, hand sanitizer, and chemical soaps to stay clean outside. I don't believe we do. It just adds weight, it pollutes, and it kills the very bacteria that keep you healthy. We're not touching elevator buttons here. We're in the wild with access to rivers and sand and mud.
Even if soap is labeled biodegradable, it doesn't break down properly in cold mountain streams. It needs soil, warmth, and time. Without that, it can pollute the water and harm fragile ecosystems. If you do use biodegradable soap for camping or hiking, step at least 60 meters away from water and let the soil filter it.
Regular soap is even worse. It's full of synthetic chemicals that strip your skin's natural oils, disturb your microbiome, and mess with your hormones. Harsh soaps strip your skin's microbiome, the good bacteria that actually protect you. And it just doesn't belong in nature.
But here's the magic. When you let your skin be free from all the scrubbing and stripping, you begin to feel your body regulate itself. Your skin becomes softer, stronger, more in tune with the elements. When else in life do you get to truly feel your natural oils flourish?
Washing in the wild: river, stream, lake
Whenever possible, I take a dip in a river or stream. Skip the lakes. They are fragile ecosystems and often it's also forbidden to take a dip. If you need a wash, carry some water out of the lake and wash yourself further away. Let the earth do the filtering.
On long-distance trails, the standard hiker bath is simple: a wet bandana or pack towel, start with your face, work down to your feet. Two minutes of focused wiping at the end of the day does more for how you feel in the morning than you'd think. Save the river dip for the days you find clean moving water.
Same with peeing and pooing. Never do it close to a water stream. Keep the wild clean and it will keep you well.
If you use soap (minimal amounts of biodegradable only), step at least 60 meters (or 200 ft) away from water sources and let the soil filter it. The best biodegradable soap for camping is no soap at all most of the time. When you do need it, a tiny smear of Dr Bronner's diluted in water handles body, hair, dishes, and laundry. One bottle lasts a season.
What's in my hiking hygiene kit (and what I skipped)
Keeping things minimal means less weight, less trash, and fewer things harmful to the environment. Here's what I carried on my GR11 hike in the hiking hygiene kit department:
- Tiny pack towel that doubles for face washing. I use a Kula Cloth, which hangs on my backpack and dries fast. Sea to Summit also makes excellent ultralight pack towels.
- Toothbrush and DIY tooth powder: natural and safe to spit out
- Culo Clean travel bidet: portable bum-cleaner that screws onto any water bottle. No toilet paper, no trash.
- Menstrual cup (OrganiCup): perfect for a period on trail with zero waste
- Small oil mix for my face: castor, rose, and argan oil (more on that below)
- Copper tongue scraper: starts the day fresh
- A pee rag. I use a second Kula Cloth
- Natural electrolytes for sweaty days
- Spirulina powder to help restore muscles
- Activated charcoal powder for food poisoning or bad water
- Blister plasters (Compeed) and tape wrapped around my hiking poles
- Silicone earplugs for quiet nights
- Small amount of baking soda (occasional natural deodorant)
- Chai tea and spice mixes to keep trail food interesting and the digestive system happy
- Extra hair tie
- A plastic bag to carry out any trash
For the ladies specifically, the question I get most is about yeast infections on long hikes. What works for me: merino underwear that breathes, one clean pair set aside for sleeping, going commando under hiking shorts when I can, and letting everything air out at night. That solves 95% of it. Wash the dirty pair in a stream (away from camp), dry on the pack as you walk the next day. The pee rag handles the daytime drops.
Fun fact about the oils: I bought them directly from the makers. Castor oil and rose oil I bought on the street in Dominica, a tropical island country I travelled to by sailboat and where I hiked the Waitukubuli National Trail. Argan oil I got on the street in Morocco where I spent the last two winters in my van. Small spa treatment for the face, every evening.
Culo Clean
Clean, practical and environmental friendly way to clean your bum! It's just a lid that you can screw onto any bottle. Leave no trace and keep your culo clean :)
What I didn't bring hiking and wild camping (and I hope you don't either):
- Wet wipes (heavy and leave trash)
- Bottles of shampoo
- Chemical soaps
- Hand sanitizer
- Deodorant (more on that below)
Instead, I kept my hygiene essentials natural and simple.
Oral hygiene: toothbrush, tongue scraper, pine needles
I make my own tooth powder. It's super light, simple, and natural, so I can spit it out in nature (away from water streams). Commercial toothpaste is full of chemicals. I don't recommend them for you or for nature. At the end, it's the bristles that matter the most.
Actually, my favourite and the most natural and oldest toothbrush in the world is the miswak branch. My teeth get super clean and smooth with it. Zero waste, zero chemicals, zero packaging.
Another little oral hygiene trick from the wild: pine needles. They make great toothpicks.
Since I'm on it, what I really swear by is a copper tongue scraper. First thing in the morning. I really believe already half of the hygiene and health is set for the day. It eliminates all the built-up waste your body wants to get rid of overnight. Starts the day fresh and clean.
Bathroom on the trail: the real talk
Going to the bathroom in the wild is one of the biggest mental hurdles for some. But it's not complicated. It's actually much more natural than sitting on a toilet.
Follow Leave No Trace principles:
- Dig a hole 10-20 cm deep and at least 60 meters away from water sources.
- Use a portable bidet instead of toilet paper. Or pack out toilet paper (a resealable bag works).
- Use a pee rag to catch the drops. I attach mine to my backpack strap so I can use it even with my backpack on. Like this, the underwear stays cleaner much longer. I can wear them for one week instead of two days. I'm joking. I do wash them sometimes.
- If required by regulations, use a wag bag to pack out human waste.
It might feel awkward at first, but once you do it a few times, it's just part of life out there.
Deodorant, sweat, and smelling like you
Deodorant doesn't make you cleaner. It doesn't make you healthier. It just masks smell. Sweat is normal and actually healthy. It cools you down and flushes out toxins.
No one expects you to smell like flowers in the wild, and trying too hard just adds unnecessary hygiene products to your pack. Out here, you just smell like you.
What you eat also changes how you smell. So take it easy on the processed cookies and your sweats will be less funky. Sometimes I use a little bit of baking soda as deodorant if I really need something. That's it.
Feet first: socks, shoes, and blisters
Your feet are your thru-hike foundation. Treat them well and you'll go far. A little foot massage in the evening goes such a long way.
- Dry your socks and shoes every chance you get.
- Wear two pairs of socks to prevent blisters and reduce chafing.
- Choose merino wool socks. They resist smell, breathe, and don't shed microplastics. BRANWYN makes great merino base layers and underwear.
- Buy shoes two sizes bigger. Your feet will swell on trail. I wear Altra Lone Peak trail runners with the wide toe box, so there's lots of space.
- Carry tape around your hiking poles (no extra weight, always accessible).
A little wool tucked in your sock where something rubs can save you from a blister. Whether it's blisters or pain somewhere, a bit of raw merino wool changes everything.
Natural fabrics vs synthetic: the microplastic truth
A lot of hiking gear is basically plastic. Polyester, nylon, synthetics. Sure, it's light and dries fast, but it also traps bacteria and makes you smell worse.
Natural fibres like merino wool resist smell, breathe better, and last but not least, don't leech microplastics into your skin or into nature. Every time you wash synthetic fabric, thousands of tiny plastic fibres end up in waterways, in our food, even in our blood.
My rule: the layers closest to my body (base layers, socks, underwear) are always natural. The shell layers (rain jacket, windproof) can be synthetic because they don't sit on my skin and they need to be light.
Digestive health is hygiene too
Your gut health affects your hygiene more than you think.
If you're constipated, you'll feel worse. If you get diarrhea, things can get messy fast. The last thing you want is diarrhea or constipation, which then turns into a less hygienic situation.
What I carried:
- Chai tea and spice mixes to keep trail food interesting and the belly happy
- Natural electrolytes for sweaty days
- Activated charcoal powder for food poisoning or bad water. Saves a life when things go wrong.
- Spirulina to help restore the muscles
- A plastic bag to carry out any trash
Good digestion makes life (and hiking and camping) a lot cleaner.
Period on the trail
Yes, you can stay clean on your period while hiking.
On trail, I prefer to use a menstrual cup (OrganiCup). It's practical, zero-waste, and no need to carry pads or tampons or a sealable plastic bag full of trash. NL readers can grab a menstrual cup on Bol.
I plan to make a video on how to approach the moon time on trail or when camping. Subscribe to stay in the loop.
Menstruation Cup
You only need one. You can reuse it, over and over again. Try it!
Check the Organicup out on AmazonHair on the trail
Hair on the trail is simpler than you think.
I kept my hair in braids all the time, so I don't need to brush it or bring a brush. I washed my hair during some of the zero days at the campsite. And that's it. You really don't need to wash your hair every week. Your scalp adjusts when you stop washing it every day.
If you get the opportunity, a fresh rinse in a river stream could do magic. And mud on the scalp can do wonders for the grease.
Water on trail
What a wealth to be drinking fresh mountain water. I hardly carried water on the GR11 as there was enough to be found in streams. Of course filtered, because with lots of cows and sheep around, water can be contaminated. And the higher up you take the water, the better.
The filter I used on this trail was the Katadyn BeFree. Very lightweight, very simple, and it does the job for this kind of trail. The LifeStraw is another solid option if you want to drink directly from streams. In my van and for sailing, I use the Maunawai water filter (5% off with code OP2020) for better filtration and mineral capacities, but the Maunawai hiking filter is a little bit heavier, so for long distance I go for a lighter option.

Sleep hygiene
At night, I switch into clean layers: merino leggings and a merino thermal top. It feels like a reset button. I even carry a tiny pillow. Luxury? Maybe. But waking up rested makes every day better.
I also put everything back in its place each night so I can exactly find it tomorrow morning again. Saves a lot of time when you're starting cold at sunrise.
Mental hygiene
Hygiene on trail isn't just about your body, it's about your mind too.
I had some struggles in the beginning of this trail, which I shared about in the first video of this series on hiking across the Pyrenees. My main advice here: you can either complain about how dirty it is, how tough it is, how much your feet hurt, or how wet the rain is. But it's not going to change anything about the situation.
Focus on what's amazing. Like the fact that you're actually out there hiking, breathing clean air, connecting to nature. It keeps the spirit high, not only for yourself, but also for your hiking buddy.
Another little thought that often helps: realize it can always be worse.
Leave the trail (and yourself) better
Every choice leaves a mark. What you wash with. Where you spit. Where you pee or poo. It all flows downstream.
Trail hygiene is about respect. For yourself, for others, and for nature.
Walk at least 60 meters away from lakes and streams before brushing, spitting, washing, peeing, or pooing. Pack out what doesn't belong in nature. But even better: don't bring any chemicals in the first place that don't belong in nature or on you either.
You will never feel fully clean on a thru-hike. And that's part of the magic. You will just feel healthy, fresh enough, and leave the trail better than you found it.
The goal is simple. Keep the wild places wild, and keep yourself wild.
