Tugela Falls
Drakensberg · KwaZulu-Natal · South Africa
Most waterfalls you just look at. Tugela Falls, you earn.
It sits at the northern end of the Drakensberg range, inside Royal Natal National Park in South Africa, dropping about 948 meters down the escarpment in a series of stages. Depending on which measurement you trust, that makes it the second-highest waterfall in the world. But the falls themselves aren't really the point of going — the hike to the top is.
I did this in early April, and it's one of those days I still think about.
