If one is not a birder, then Mkhuze Game Reserve can still be a paradise but for the variety of mammals and reptiles. As it has the Big Five (lion, leopard, elephant, buffalo and rhino) in the reserve, getting out of the car is not an option unless at the designated picnic spots, water holes or bird hides - even then it is good to be wary.
It is also amazing how many to see how fast most people drive in the park, barely within the speed limit. I am sure they miss most wildlife as they cannot see much when driving "fast". Anyway, here are some of the animals I saw in amongst the birding.
Kudu ram
Young impala ram
Hippo hippoing ......
Vervet monkey
Impala ram
White rhino
Waterhog
Nyala doe
Zebra
Young Nyala ram

I think that should be enough to give you a feel for Mkhuze Game Reserve.
