We were setting up our tent when we heard there were rhinos at the watering hole. We packed up as fast as possible to see the rhino. I had seen one rhino before at Nakuru National Park in Kenya. It was so far away that I do not know if it was white or black. Within a few minutes I had much improved viewings at Hlane Royal National Park.
Hlane only has white rhinos. The black rhinos, which are more endangered, can be found at Mkhaya National Park in Swaziland.
The rhinos were so exciting to see. A few mothers had young children with them.
I learned that rhinos do not have good vision, as well as they return to the same place to defecate. There were many large piles of rhino poop, which can then differentiate the rhino poop from the elephant poop.
Check out the photos below of the rhinos I saw. If you missed the lion or elephant posts, you can see them here and here.

It looks like your trip to Hlane Royal National Park was worth it. It must have been very exciting to see so many rhinos.
It was fantastic!
