If you come into close proximity to a bear, your options are limited.

You can’t outclimb or outrun a bear, even if you’re traveling downhill, experts say.

And — regardless of what everyone’s favorite bear-punching boxer Carl Moore says — you probably shouldn’t approach a bear and take a swing.

Your best bet, as a large group of tourists in Yellowstone National Park recently learned, is to keep your distance in the first place.

The photo-snapping tourists found themselves running for safety after they got too close to a black bear and her cubs, upsetting the animals, according to the Montana Fish, Wildlife and Parks service.

The incident, which was recorded by a videographer with the service, shows some tourists running for their vehicles while others try to stay out of the way. At one point, the zigzagging animal appears to charge several people, unleashing a frightening burst of speed.

“Keep moving!” a man can be heard yelling. “Go! Go!”

Bob Gibson, communication and education program manager with Montana Fish, Wildlife and Parks, told USA Today that the tourists were “very much in danger.”

“The most dangerous place is between a mom and her cubs,” he said.

Gibson told the newspaper that the cubs were about 13 months old and he noted that the mother was not as aggressive as she could have been if they were newborns.

“If they had been born in the last few days, it could have been much worse,” he said, adding that people should stay at least 100 yard away from bears.

“It serves as a reminder that wildlife can be unpredictable,” the service wrote on its Facebook page. “For your safety and theirs, respect wildlife and give them room to roam. View and photograph from established observation areas. Stay a safe distance to reduce stress on wildlife.

“Luckily, no one was hurt and these bears made it safely back to the forest.”
