Had some great sightings to ourselves over the years...
Many a leopard as expected and a couple of times came across hunting lions and once a cheetah kill.
One of the funniest was travelling down the S100 (in the 90's) only to come to a group of about 20 cars watching 2 sets of lion ears in the grass...we couldn't get passed so turned around and a few corners later had a big beautiful male lion walking across the road all to ourselves...it was especially nice in the circumstances.
A more recent sighting was on the S128 near LS where I joined about 5 or so cars watching lions. Supposedly 3 females in the distance and asleep. One of the cars had tourists that said they had been with them for the whole day. It had been about 35-40 degrees so I thought that was strange because the lions were hardly going to move in the heat. Anyway it was about 2 hours before closing time and suddenly everyone just left the sighting and one car went around the corner for some reason. Being summer, a sudden pre thunderstorm wind started up and with the numerous giraffe in the area that the lions had been aware of, the lions took the opportunity to hunt.
I was in the car alone and couldn't believe my eyes when it turned out to be about 10 adult lionesses all chasing this one giraffe right in front of me jumping at it...they seemed to pull it down on the other side of the road in some thick bush (but couldn't tell for sure) and a few more lions came running in to where the giraffe had been chased. I didnt see the actual kill with my own eyes but many vultures in the area in the following days probably confirmed the lions success.
I was shaking from all the adrenalin when the car came back around the corner and the tourists asked where did the lions go? I couldn't really explain I was still shaking so much but managed to tell them in the end...they hardly believed me!
Anyway my drive (and trip) was made so I took a slow drive on the S29 where some reedbuck, a coqui francolin and 2 cheetah brothers walking in the road put on a show for me.
A drive I wont forget
