update (12 Aug 2016): South African National Parks (SANParks) advises travellers planning to use the R536 leading to Paul Kruger Gate on 13 August 2016 for entry or exit Kruger National Park to to use alternative routes (Phabeni Gate and Numbi Gate) because they are not sure if the demonstrations would have stopped or not.
According to a statement issued by South African National Parks (SANParks) on 09 Aug 2016, Kruger National Park's Paul Kruger Gate is currently inaccessible due to protests on the R536 leading to the gate. Visitors to Kruger National Park are advised to avoid the popular gate and to use alternative routes such as Phabeni Gate and Numbi Gate to access and exit the Park until further notice. It is unclear for how long the protest action will continue. Phabeni is about 10km away from Hazyview on the R536 and Numbi is about 31km from White River/52km from Nelspruit on R40.We'll keep you posted!
