Bears and RVs in North America: How to Travel Safely
Yellowstone, Banff-Jasper, Alaska, Gaspésie: how to store food, use bear spray, and avoid bad encounters with bears on an RV or campervan trip — with what the research actually shows.
A motorhome creates a false sense of security around wildlife: doors closed, you feel safe. Yet every summer, park managers across the Rockies and Alaska report gutted coolers, tipped-over bins and bears that have learned to read the shape of a van as an easy meal. The good news: a handful of simple habits are enough to travel with peace of mind — and to protect the bears themselves, since an animal habituated to humans is almost always put down.
Why a motorhome isn’t a safe
A grizzly or black bear can detect a scent from several kilometres away, and its smell-based memory quickly links “white van” with “free meal” after just one cooler left on a picnic table. A motorhome’s walls don’t stand up to a determined animal: roof vents cracked open for airflow, poorly latched storage hatches and pull-out outdoor kitchens are all weak points. Around Yellowstone and along the Banff-Jasper corridor, rangers remind visitors every season that a vehicle only protects you if nothing scented is visible or reachable from outside.
The habits that actually matter
- Store all food, pet kibble, toothpaste and sunscreen inside the locked living area — never in the cab or on the outdoor table, even for a ten-minute break.
- Cook and eat a reasonable distance from where you’ll sleep whenever the campground layout allows it, and wipe down counters and the barbecue grate immediately.
- Use the metal bear boxes provided at most North American national park campgrounds every single time.
- Dispose of rubbish in the bear-proof bins provided, never in an ordinary bin and never kept in the van overnight.
- Never feed an animal, even “just for the photo”: it’s often the first step toward a bear being put down a few months later.
These rules aren’t excessive caution. A 2014 study published in Frontiers in Ecology and the Environment by researchers Jack Hopkins and Paul Koch (UC Santa Cruz), based on isotopic analysis of black bear hair and bone spanning nearly a century in Yosemite, found that the share of human food in bears’ diets fell dramatically after the park tightened enforcement of bear-resistant canister requirements in 1999 — hard evidence that these habits genuinely work (Google Scholar page).
Where the risk is real right now
Grizzly encounters have more than doubled in a decade across Greater Yellowstone, according to park managers, driven by a growing population. The same vigilance applies along the Banff-Jasper corridor and on the high plateaus of Colorado. In Alaska, around Denali, an approved bear-resistant canister is mandatory for any unsupported hike off the maintained trails — free to borrow at the visitor centre. Further east, the black bears of the Appalachians, encountered along the Blue Ridge Parkway, and those of Québec, common in the Gaspésie, are smaller but just as opportunistic near busy campgrounds.
Bear spray: the best insurance
Effective, non-lethal and recommended by every North American park service, concentrated pepper spray (capsaicin) remains the best protection in a close encounter — provided you’re actually carrying it and know how to use it. A 2025 study published in the Journal of Interpretation Research by Anna B. Miller and co-authors, surveying 566 visitors to Greater Yellowstone, found that 27% never carry spray at all — often first-time visitors or day-use groups — and that on-the-ground communication (rangers, signage, demonstrations) significantly increases actual carry rates (Google Scholar page). In practice: buy it locally — it can’t travel in checked or cabin luggage —, keep it within reach (belt, door pocket) rather than buried in a backpack, and practise releasing the safety before you set off on a hike.
Travelling with kids or a dog
Children running ahead on a trail and dogs off-leash are two classic triggers for a defensive charge: stay grouped together, talk loudly in low-visibility areas, and keep the dog leashed both near the van and on the trail — see also our guide to hiking from your campervan. A 2021 study in the same Journal of Interpretation Research (Freeman, Lawhon, Newman and Taff), focused on Appalachian Trail hikers, found that adopting good food-storage habits depended less on fear of a fine than on the perception that “everyone else does it” (Google Scholar page) — a good reason to set the example rather than wait to be forced into it.
What to check before you set off
When picking up a vehicle from an agency near bear country, ask whether a bear canister or bag is supplied or available to rent, and check that the exterior storage locker actually locks. Many US and Canadian campgrounds post site-specific rules at the entrance: read them, since they vary from one site to the next depending on current animal activity. Our guide to renting an RV in the USA covers the practical side of a rental on the other side of the Atlantic — and one last habit: a water tap or bin badly placed at the forest edge is also a route wildlife uses often, so it’s worth avoiding for an overnight stop.
