Scary footage of a "tracker" at a private game reserve in South Africa letting a large, male lion walk right up to him.

The video was filmed in Kapama Private Game Reserve in the Greater Kruger National Park area, just before sunset on September 5.

It shows the brave man, sitting on the end of a safari vehicle, having an extremely close encounter with the big cat.

At one point, the lion's mouth is no more than 30 cm away from his foot.
