Hey Mattie
I have been trying to wrap my head around what advice to give you here, so sorry for the late input
It’s rather difficult, because the best camps for camping IMO aren’t in the best game viewing areas of the park, so one has to compromise.
Statistically one can’t beat Lower Sabie for predator sightings, followed by Satara and then Skukuza, but these aren’t fantastic camping spots and it can get crowded on the roads.
I consider the Letaba/Mopani area the worst in the park for predator viewing. Things improve towards Shingwedzi
I think Flutts has hit the nail on the head with her post above; especially Tamboti as an option
Are you camping due to cost or because you love camping as there are alternatives which are only slightly more expensive.
EH5 huts at Lower Sabie, Tamboti, etc
