The question was posted to me last week.
My answer to this is as follows:

The african bushveld, including Kruger National Park, Pilanesberg National Park and Madikwe Game Reserve, is remarkable at any time of the year!

I prefer taking leave and visiting the parks at around August or September. At this time of the year it is starting to become warmer and it generally doesn't rain yet, so we can camp comfortably. The bush is also not as thick yet, which means we tend to see more of the mammals that the bush has to offer and amazing photograph opportunities are presented.

On the other hand, I also love visiting both Kruger and Pilanesberg on safari during the summer months! During summer our South African bushveld gets flooded with summer visitor bird species and the bush is full of new life. The summer rains bring with it, lush green vegetation which makes it the perfect time for the herbivores to raise their young. Most of our grazers and browzers' young are born during the hot, wet summer months when food is plentiful.
Even after just one rain shower, it seems like everything is clean again and all the hardships brought by the cold dry winter has been washed away.

Clear blue skies during the winter months bring a different beauty to South Africa's lowveld. Winter months show us just how remarkable nature is to be able to withstand and survive all the  obstacles and hardships this planet throws at it.
The best part of a winter wildlife safari for me, is the evenings spent around campfire, listening to all the night sounds mother africa plays in the background.

To be honest, I think the only reason we go on our holiday safari during August or September each year, is purely because we were taught to. The cry of a black-backed jackal or the sight of a pride of lions when on an open vehicle game drive is just as exciting during one season as it is in the next.

So when is the best time to go on safari according to me? Whenever you have the time! Whether you visit the bush when it is hot, cold, wet or dry, nature is always beautiful!

At last!!!
Our new website is complete! It has been live with some of the pages for quite some time now but we were working hard in the background to get all the pages completed and loaded.
We have a lot more safaris on offer than before and we will continue to add more as we go on. Please feel free to write to us if you feel there is a need for something we are not offering yet.
Ama-Zing African Safaris' now also offer airport transfers / shuttle services from OR Tambo International Airport.
I am looking forward to start blogging and loading new photographs of our safaris and game drives in Kruger National Park and Pilanesberg National Park. 
I was busy studying and writing exams the last two months and I started preparing for the trails guide treory exam in October this year, so I am also planning on adding some interesting facts about our African Big5!
