It’s an interesting sight to see for visitors to Banff National Park, but it can also be very dangerous.

Elk return to lower elevations this time of year for mating season and can be very aggressive.

Human wildlife conflict specialist Steve Michel says people should keep a healthy distance if they spot one of the bulls.

Michel tells The Calgary Herald stay in your cars or at least three bus lengths away.

He also warns to keep your dogs close; elks can feel very threatened by pooches and try to attack.
