Yellowstone National Park Safety Guide
Health, security, and travel safety information
Emergency Numbers
Save these numbers before your trip.
Healthcare
What to know about medical care in Yellowstone National Park.
Healthcare System
Yellowstone has limited medical facilities within the park, with the nearest full-service hospitals located in gateway communities. The park operates several clinics during summer months staffed by medical professionals, but serious cases require evacuation to regional hospitals.
Hospitals
In-park clinics at Lake, Mammoth, and Old Faithful (seasonal); nearest hospitals: Livingston HealthCare (MT) 53 miles north, St. John's Health (Jackson, WY) 57 miles south, Eastern Idaho Regional Medical Center (ID) 110 miles west
Pharmacies
Limited pharmacy services at park clinics; full pharmacies available in gateway towns (Gardiner, West Yellowstone, Cody, Jackson); bring adequate prescription medications for your entire stay plus extras
Insurance
Travel medical insurance is HIGHLY recommended; ensure coverage includes emergency evacuation, which can cost $20,000+ for helicopter rescue
Healthcare Tips
- Carry a complete first-aid kit including blister treatment, altitude sickness medication, and bear spray (not for medical use but essential safety)
- Know the symptoms of altitude sickness (headache, nausea, fatigue) as most of Yellowstone sits above 7,500 feet
Common Risks
Be aware of these potential issues.
Bison, bears, elk, and moose cause more injuries than any other park hazard. Animals appear docile but are wild, unpredictable, and can charge without warning.
Boiling water and thin, fragile crusts around hot springs can cause severe or fatal burns. People have died falling into thermal features.
Theft from vehicles at trailheads and parking areas, of visible valuables.
Hypothermia, heat exhaustion, and dehydration due to rapid weather changes, high altitude, and variable conditions.
Falls on uneven terrain, slips on loose gravel, and hiking beyond one's fitness level leading to exhaustion or injury.
Scams to Avoid
Watch out for these common tourist scams.
Unlicensed operators offering discounted tours or backcountry guides without proper permits or insurance
Individuals posing as parking attendants collecting fees at unofficial lots or trailheads
'Guides' charging for guaranteed wildlife sightings or access to restricted areas
Safety Tips
Practical advice to stay safe.
Wildlife Safety
- Carry bear spray and know how to use it (practice removing safety clip)
- Never run from bears or wolves - back away slowly
- If a bison stops grazing and looks at you, you're too close - back away
- Store all food, garbage, and scented items in bear-proof containers
Geothermal Safety
- Stay on designated boardwalks and trails
- Assume all thermal water is hot enough to cause serious burns
- Test boardwalks with a trekking pole if they appear damaged
- Keep children within arm's reach at all times in thermal areas
Driving Safety
- Use pullouts to view wildlife - never stop in travel lanes
- Watch for animals crossing roads, at dawn and dusk
- Obey all speed limits - wildlife collisions are common
- Fill gas tank frequently - distances between services are long
Hiking Safety
- File a hiking plan with someone before backcountry trips
- Carry the 10 Essentials: navigation, headlamp, sun protection, first aid, knife, fire starter, shelter, extra food, extra water, extra clothes
- Turn back if weather deteriorates - summits will be there another day
- Drink water regularly - altitude and dry air increase dehydration risk
Information for Specific Travelers
Safety considerations for different traveler groups.
Women Travelers
Yellowstone is generally very safe for women travelers, including those traveling alone. The park has a strong ranger presence and most visitors are families and outdoor ensoiasts. Standard precautions for wilderness travel apply.
- Join ranger-led programs if hiking alone - they're free and provide safety in numbers
- Trust your instincts if someone makes you uncomfortable - move to areas with other people
- Carry a personal safety alarm along with bear spray
- Let someone know your itinerary each day, for backcountry trips
LGBTQ+ Travelers
Full legal protections in Montana, Wyoming, and Idaho where the park is located
- Most visitors are focused on nature rather than social issues
- Park staff are trained in inclusivity and nondiscrimination
- Public displays of affection are unlikely to draw attention in crowded areas but use discretion in remote areas
- Consider staying in more progressive gateway towns like Jackson, WY if concerned about social acceptance
