There are no restrooms, privies or outhouses along most trails in the wilderness, or even close in to many developed areas in parks.
After we get to a trailhead (start of a hiking trail), and after we have packed up gear in our kayaks & canoes, we always plan to make one last stop at a restroom / outhouse, even if people are sure they don’t reeeealy need to, to prevent having to dig one more hole in the wilderness.
Away from toilet facilities, to deposit solid human waste, start by setting duff, pinecones, twigs aside carefully, then dig the hole. Mount Rainier says: “to promote decomposition, choose a site in organic soil rather than sandy mineral soil.”
Cover and disguise the cathole when finished by replacing duff, pinecones, etc.
(Yosemite) Deposit solid human waste in catholes (personal latrine) dug six inches deep at least 100 feet from water, camp, and trails.
(Grand Teton) “Urinate at least 200 feet away from any water source in rocky areas that will not be damaged by animals digging for salts and minerals found in urine. Bury feces 6-8 inches deep in soil and at least 200 feet from lakes, streams and wetlands.”
(Grand Canyon, 2021) “Where toilets are not available you must carry out your used toilet paper (a plastic ziplock bag works well) and bury feces in a small hole about 6 in / 15 cm deep. Be sure you are at least 200 ft / 60 m from trails, campsites, and water sources. Along the Colorado River, urinate directly into the wet sand at the river’s edge.”
(Everywhere) “Pack out used toilet paper, tampons, sanitary napkins and diapers in sealed plastic bags. Do not bury or burn them or dump anything in the backcountry outhouses. If you are in snow and can’t dig a hole into soil you are expected to pack out your waste as well.”
To truly be able to leave no trace and follow backcountry rules about camping the proper distance from a lake or digging your personal latrine hole the proper distance from water, etc.,
you will need to know how far 100 or 200 feet is.
Lay out a tape measure at home for 100 feet and walk it and count your paces.
It isn’t possible to dig your cathole deep enough by scraping the soil with your boot heel/rock/stick, carry a small lightweight garden trowel (lower cost than some for sale at recreation supply stores). The garden trowel might have a blade that is 6 inches long, you can measure it. The trowel should only be used to dig the hole and should not get fecal matter on it. If your aim when you squat does not work to get the solid waste directly into the hole you dug, use a stick to push it in, not the trowel.
You can pack your trowel in a small bag with the toilet paper, trash bag for the used toilet paper, and some hand sanitizer or wipes (that need to also go into the trash bag after use).
Digging one big latrine for multiple people to use is not recommended, as “the digging and use of temporary latrines by backcountry visitors is almost always an inappropriate method for disposal. The larger the concentration of feces, the more time needed for decomposition, which increases both the likelihood that feces will be discovered by other visitors and that pathogens will come into contact with ground water.”
When you urinate on durable surfaces (rocks, gravel) that will not be damaged by animals digging for salts and minerals found in urine, (and not on plants that animals could try to chew on to get the salt) you could dilute the urine with a sprinkling of water.

At many parks, in alpine zones and/or for all climbers, you must pack out all your own waste. See human waste and trash at: ‘The rules (and their reasons) while climbing in Yosemite’, http://www.climbingyosemite.com/services/regulations/
(Grand Teton) “Use Rest Stop Bags. Pack out solid human waste and toilet paper on alpine climbs. There is no good place to dig a cat-hole on alpine climbing routes and solid human waste left under rocks can last a long time in that environment.”
“On Jackson lake all solid human waste must be removed from any campsite or shoreline area for proper disposal.
At the Lower Saddle in Garnet Canyon, all solid human waste must be carried out.
In Garnet Canyon and in other high-use areas, such as Hidden Falls and Inspiration Point, it is also suggested that solid human waste is carried out. Bags for removal are given out at several locations.”
(Amistad National Recreation Area, 2021) “Park visitors are required to carry out all solid human waste and toilet paper from backcountry areas of the park with a commercially-produced, spill-proof, and trash-container-safe waste bag system or with a dump-station-compatible waste system.”
Proper waste disposal not only keeps the backcountry looking pristine, it is extremely important for health and safety of campers and wildlife.
Over 100 bacteria, protozoans, and viruses are potentially present in human feces and capable of causing illness.
Your toilet paper trash bag should be a separate one from the bag you carry for food trash.
Have a small trash bag handy on the trail, big enough for more than your own trash.
We have had competitions to see who could find and clean up the most (or weirdest) litter.
Get the trash into the bag as you create it, micro-trash often falls out of pockets and litters trails.
When you are about to leave, check your campsite and lunch stop for microtrash —look for bandages, twist ties, fruit peels, bits of wrappers, stray potato chips, torn corners of candy bar wrappers and power bars, plastic bottle caps, bits of G.O.R.P. etc.
Don’t burn or bury any trash, or dump anything in composting backcountry outhouses, even orange peels you think will biodegrade.
Please pick up after less thoughtful people who have gone before you.
If you decide to improve your karma, and the beauty of an off-trail spot, by cleaning up used toilet paper others left, remember that it has germs and carefully use a couple of twigs to get it into your trash bag without touching it, or even better, bring some extra non-latex first aid gloves to use:

“Cigarette waste is the most commonly littered item in the US,
with 1.69 billion pounds polluting the environment every year.”
“While many people believe that cigarettes are biodegradable, the filters in almost all cigarettes are actually made of cellulose acetate, a type of plastic. When disposed of improperly, they release a long list of harmful chemicals into the environment (cadmium, lead, formaldehyde, arsenic, etc.). In addition to these challenges, carelessly tossed cigarette butts can also start forest fires, potentially damaging hundreds or thousands of acres, or make their way into the nests of birds and other animals along with other micro-trash items.”
