Here are my views and experiences of the roads in the Satara area (in no particular order):
The H6 - I've had brilliant sightings of lion, leopard, cheetah and african wild cat along this road. I far prefer it to the S100 (although also an excellent road) as there is less dust, it's elevated because it's tarred so it's easier to spot things when the grass is long and its beautiful open plains have lots of interesting birds. The Sweni Bird hide at the end of this road is probably my favourite bird hide in KNP, always plenty happening in terms of both birds and mammals - I can sit there for hours!
The S41 (South) - another one which is a predator rich road. I have seen both lion and cheetah make kills on this road. Lovely for birding too. I have also had 4 separate sightings of Sharpe's Grysbok along this road (three of them close to the little bridge/causeway of the N'wanetsi river in the thick scrub, so keep a look out for them). I have seen lots of exciting birds and mammals at Gudzani dam, another place I can sit for hours. Highlights include Wild Dogs and a Serval fishing for barbel.
S100 – this is a great road. Predator rich, great for plains game. I doubt I need to say much about it. I have had brilliant sightings on this road but, as with any road in the park, days where I haven’t seen so much as an impala. My advice, unless you’re the first one on the road in the morning do the H6 first and then come back along the S100, the dust combined with the rising sun will destroy you and your photographs if you’re not in front.
The S90 and the S41 (North) - this is generally quite a quiet road, but I have had good luck with elephant (nice tuskers), cheetah and lion. It's also a brilliant area to tick some more grassland birds off your list. My favourite sighting was a Kurrichane Buttonquail with tiny little chicks crossing the road - one of the cutest things I've ever seen!
The H7 – this is a brilliant road for lion, cheetah and leopard, and of course the resident orpen pack of wild dog. I have seen lions make a kill at Nsemani Dam on two occasions. My best cheetah sighting of all time was also on this road near the S39 junction. The only negative is that it’s a relatively busy road (well for the central area anyway).
The S36 and the S126 – my most successful leopard roads in the park, particularly the Sweni River road. Both these roads are brilliant for predators (I’ve seen caracal along the S36 north), big herds of buffalo and if you’re lucky some nice tuskers might make an appearance. Also brilliant birding roads in my opinion.
The S39 – This my favourite road in the park in terms of scenery and due to the fact that you can drive for an hour in peak season without seeing another vehicle (although I have no idea why). I have seen Verreaux’s Eagle Owl, Barred Owlet, African Scops Owl and Pearlspotted Owl on one drive. Also brilliant for predators. I have seen a leopard take a warthog along this road and also seen the Timbavati pride with numerous kills over the years. Surprisingly, in terms of my statistics, this is my most successful cheetah road in the park. The Ratel Pan bird hide is probably my second favourite bird hide in the park, brilliant for water birds and great for photographing hippos.
Okay, I could write a book on the Satara area I love it so much, so I’ll stop now before I write another 2 pages! Either way, it’s a beautiful area filled with many surprises and never disappoints! If you have any questions on any of the other roads in the area please don't hestitate to ask
