suggests that the gorge may be relatively young and have formed in the last 2 million years.

Flooding

As the Luvuvhu River is still a young, active river, flooding is common and the gorge is often cluttered with debris such as fallen trees.

Access

Access to the gorge is extremely limited due to its steepness and its status as a wilderness area of Kruger. Nevertheless, some walking trails approach and enter the gorge from both the Makuleke area as well as from the Kruger side.

Wildlife

The gorge holds a variety of wildlife including abundant
