RidgeSyncBackpacking Hygiene: Catholes, Hand Care, and Staying Clean on Trail
Good backpacking hygiene prevents more trail illness than water filtration does: dirty hands, not contaminated water, are the leading cause of backcountry GI illness, since hikers touch shared surfaces and food after using the bathroom without washing. The other pillars are simple: dig catholes 6 to 8 inches deep and 200 feet from water, pack out toilet paper where required, and wash at least 200 feet from any source.
None of this is complicated, but skipping it is how norovirus outbreaks start on popular trails and how one sick hiker becomes an entire group's ruined trip.
Digging a proper cathole
- Find the right spot
Choose a site at least 200 feet (about 70 adult steps) from any water source, trail, or campsite, with loose, dark topsoil that supports faster decomposition.
Tip Look for organic-rich soil under leaf litter rather than sandy or rocky ground.
- Dig 6 to 8 inches deep
Use a trowel to dig a hole 6 to 8 inches deep and 4 to 6 inches wide. This depth sits within the biologically active soil layer where decomposition happens fastest.
- Do your business and cover it
Fill the hole back in with the loose soil you removed, then disguise the site with leaves or a rock so it isn't obvious or dug up by animals.
- Pack out what doesn't belong
Toilet paper and hygiene products go in a dedicated sealed bag, not in the hole, in any area with high traffic, fragile soil, or a specific pack-it-out rule.
Tip A dark, opaque zip bag inside a second bag keeps this genuinely unnoticeable in your pack.
Why pack-out toilet paper rules exist
Many popular and fragile-ecosystem areas, deserts, alpine zones, and heavily trafficked corridors, now require packing out toilet paper rather than burying it, since thin soils decompose paper far slower than forest soil and catholes are already stacked too close together. Some areas require packing out everything, including waste, using a WAG bag system.
Check land-manager rules before your trip; when in doubt, pack it out, a sealed bag is a minor inconvenience compared to the problems buried paper causes in overused areas.
Hand sanitation matters more than water treatment
The single biggest lever against trail illness isn't your water filter, it's your hands. Hand-to-mouth contact after using the bathroom or handling shared gear (privy doors, bear canisters, trekking poles at a shared water source) spreads norovirus and other GI bugs far more often than drinking treated water does.
- Sanitize hands with 60%+ alcohol gel immediately after digging a cathole or using a privy, before touching food or your face
- Wash with soap and water when available, at least 200 feet from any water source, working suds into fingernails and knuckles for 20 seconds
- Sanitize again before cooking or eating, even if you washed earlier in the day
- Carry a small dedicated hand-sanitizer bottle clipped somewhere you'll actually use it, not buried at the bottom of your pack
Quotable takeaway: the fastest way to avoid getting sick on trail isn't a better filter, it's sanitizing your hands every single time before you eat.
Washing your body and gear
Wash yourself, dishes, and gear at least 200 feet from lakes and streams, even with biodegradable soap, since residue still harms aquatic life. Carry water in a collapsible container to a spot away from the source, then dump graywater on dry ground away from camp and trail.
A quick daily wipe-down with a small pack towel, focused on feet, groin, and underarms, does most of the work of a full wash in under two minutes, worth doing even on short trips to prevent chafing.
Menstruation and foot care on trail
For menstruation, a menstrual cup is the lightest, lowest-waste option for multi-day trips, rinse it with treated water 200 feet from any source or wipe and rinse fully at camp. Pack used tampons, pads, or wrappers out in a dedicated sealed, opaque bag exactly like toilet paper, never bury them, they don't decompose on any useful timescale and animals will dig them up.
Foot care prevents the single most common trip-ending problem: check feet at every break, dry socks and let feet air out during lunch stops, and treat hot spots the moment you feel them, before they become blisters. Change into dry socks at camp every evening even if your feet feel fine, prolonged dampness is what breaks skin down over consecutive days.
Frequently asked questions
How deep should a cathole be when backpacking?
Dig 6 to 8 inches deep and 4 to 6 inches wide, at least 200 feet from any water source, trail, or campsite. That depth sits in the biologically active soil layer where waste breaks down fastest.
Do I need to pack out toilet paper backpacking?
In many popular, desert, and alpine areas, yes, thin or overused soils can't reliably decompose buried paper. Check land-manager rules for your specific trail and pack it out in a sealed bag when required or in doubt.
What causes most illness on backpacking trips?
Dirty hands cause more backcountry GI illness than contaminated water. Sanitizing or washing hands after bathroom use and before eating is the single most effective habit for staying healthy on trail.
How do I handle a period while backpacking?
A menstrual cup is the lightest, lowest-waste option; rinse it with treated water well away from any source. Pack out used tampons, pads, or wrappers in a sealed, opaque bag exactly like toilet paper, never bury them.
How do I prevent blisters and foot problems backpacking?
Check feet at every break, dry them out during lunch stops, treat hot spots immediately, and change into dry socks every evening at camp. Prolonged dampness, not just friction, is what breaks skin down over multi-day trips.
