A close encounter of large predators at a designated wildlife viewing site, best observed from a safe distance.
These apex predators command the landscape: a grizzly up to 1,200 lbs and a gray wolf up to 165 lbs. Maintain 100 yards from bears and wolves (25 yards for other wildlife). Bear spray is mandatory; observe from designated viewing areas and never touch or feed.
📏 Keep your distance: Bears and wolves: 100 yards (91 meters); All other wildlife: 25 yards (23 meters)
Stay safe
Carry bear spray at all times; maintain 100-yard distance from bears/wolves; observe from designated viewing areas; never feed or touch; stay on roads/trails; back away slowly if an encounter occurs
If you encounter one
Back away slowly; for a bear, if charged, stand ground and deploy bear spray; if a wolf appears aggressive, make noise and retreat slowly; do not run
Never feed or approach wildlife — it's dangerous for you and often fatal for them.

❓ Questions people ask
Will it eat me if I surprise it?
Bears and wolves can be dangerous if surprised or defending cubs or territory. Back away slowly, avoid direct eye contact, and follow safety rules. Use bear spray if there is an imminent threat.
Can I get closer at the Grizzly & Wolf Discovery Center?
No. Maintain the 100-yard distance rule for bears and wolves; observe from designated viewing areas, and never feed or touch the animals.
What gear should I bring for safe photography?
Bring a telephoto lens (400mm+), binoculars, and bear spray. Stay on roads/trails, and never disrupt animal behavior for a shot.
When are wolves most visible in the area?
Wolves are often easier to spot in winter when prey is concentrated and can be heard howling at dusk in certain valleys like Lamar Valley.
