There has been much discussion about this issue, and rightfully so – more people than ever are getting into the outdoors, and if human waste isn’t properly considered then we’ll end up with contaminated water and an unsightly, smelly mess at your next campsite.
Unfortunately there’s also been a lot of half-baked information from otherwise reputable sources about what to do when there isn’t a toilet available. As in, what if you can’t dig a hole and you won’t go past a long drop toilet on your way out? What should you do with your… deposit? Here’s our summary.

Q1: Can I bury it?
It’s always easier to bury your poo than to carry it, but to bury it the site must meet these three requirements:
- You’re not close to water. You should be at least 100m away from the nearest stream, river, tarn, or lake. Don’t skimp on this! Just think, would you be happy drinking that nearby water if you came back six months later?
- You can dig a hole into organic soil. Poo will not break down in alpine environments, or at the beach, even if you think you can can get it well hidden in the sand or gravel, or covered with stones. That’s not good enough. You must be in a forested or subalpine zone where bacteria can thrive.
- The site isn’t very popular. If you’re in a spot that probably gets more than one party per month on average, there are simply going to be too many turds in the turf!
If you meet all three of those criteria, your answer to Q1 is YES. Dig a small hole 10-20cm deep, keeping the surface matter separate from the deeper soil. Do your business, then when backfilling make sure the surface matter goes back on top.
If you don’t meet all three of the above criteria, then your answer to Q1 is NO, and you’ll need to carry your poo for at least a short while, perhaps the rest of the trip. The following questions will help work out how.
Q2: Will I go past a long drop toilet later in my trip?
(The type that doesn’t involve the contents being flown and sucked out for transfer to a treatment station?)
If your answer to Q2 is YES, then you can poo into a compostable bag, eg cornstarch, then later in your trip simply plop it into the long drop. This doesn’t work for barrel toilets, as they’re emptied regularly and the bags break down very slowly, so will probably clog up the pumps.
If your answer to Q2 is NO, you still might not need to carry your package all the way to the road…
Q3: Will I go past any place later in my trip where I could leave my poo?
(E.g. a barrel toilet or somewhere with organic soil suitable for burial.)
If your answer to Q3 is YES, then you can poo into any bag (small to medium bin bags are good – they don’t need to be biodegradable). Later in the trip, empty the contents of your bag into a suitable hole in the soil or into a barrel toilet. You’ll still need to carry out the dirty rubbish bag, but at least it won’t weigh much anymore! I like to use a ziploc completely reinforced with duct tape as my carry bag for soiled bags. (That ziploc is also for any used toilet paper, which shouldn’t be buried – it should only go into designated toilets or in the rubbish.)
If your answer to all three questions is NO, NO, and NO, then you’ll need to carry your poo all the way out and dispose of it in the rubbish. Disposing of human waste into the rubbish is an offence unless you treat it with a product like Poo Powder, which has deodorising and gelling agents. (There are a few similar products out there.) I’ll sometimes “pre-load” some rubbish bags with poo powder before a trip if I know I’ll need to do this, e.g. an alpine trip with no toilets.
How to carry the goods
For any of the above carry-out options, it’s a good idea to double-bag your goods, as well as having either a tough drybag or reliable rigid container to contain everything, like the homemade PVC tube container pictured here. Even the most airtight container can still smell a little, so it’s best to carry these – carefully – on the outside of your pack.
