Springtime in Yellowstone National Park is always a special time for wildlife. Check out this great video of three grizzly bear cubs out on a hike with mama bear.

It is never a good idea to get too close to wildlife, but luckily there was a river separating this Yellowstone visitor from the family of bears - so there did not appear to be any danger. In the video it almost looks as if the mama bear acknowledges the presence of the visitor, but doesn't seem to be concerned. This is a great video showcasing the beauty of wildlife in Yellowstone National Park.
