A dramatic video has emerged of a lion charging at tourists in Kruger National Park, South Africa.

The footage, shot on Saturday, captures the moment the lion runs towards men on a walking tour after they disturbed him.

"The two lions were mating in the bush (you can see the lioness in the background very briefly) and we disturbed them, thus the mock charges and my jerk terrified reaction on filming!" the filmer wrote online.

Greater Kruger National Park, South Africa. Amazing video footage of how a Lion charges tourists on a walking safari ! Amazing but scary experience !

"We were on a walking safari tracking lions in the Greater Kruger National Park area. We had two extremely knowledgeable guides with us who knew the area intimately having spent months filming there, one of which was an official licensed guide. So we were as safe as one could on foot (which isn't very safe at all honestly!). The two lions were mating in the bush (you can see the lioness in the background very briefly) and we disturbed them, thus the mock charges and my jerk terrified reaction on filming!
It was an exciting trip!!! " - Video by Angelo & Heulwen
