Agree with Bushbuddies
Mopani fans love the view over the magnificent Pioneer Dam, and the well run camp and restaurant
Mopani boasts the Tropic of Capricorn Loop. A serengetti-like open grassland area which is the best in Kruger for rare antelope, and usually has high traffic of animals! However there are not many productive roads around Mopani. The attraction is to the peacefulness of little traffic
Olifants has the best view in Kruger

And as Bushbuddies mentioned, good game viewing
The H1-4 to Satara is one of my favorite roads in Kruger! It is extremely flat and open and as a result you can expect to see large herds of zebra and blue wildebeest here. These, in turn, attract lions which are often found near the road in the early mornings. As in most open areas of Kruger you can also expect to find ostriches, along with kori bustards and secretary birds.In the dry time you are going, artificial waterholes, or large dams or flowing rivers are key to finding animals! The H1-4's The northern half iis famous for the Ngotso waterholes, starting at Ngotso South in the south and ending with Ngotso North in the north. Buffalo are common in this region and so are lion. It's worth while to drive this section past all the waterholes very slowly...because predators are common here, including cheetah. I have also seen spotted hyaenas denning just north of Ngotso North.
The H1-4 ends at the large bridge which crosses the Olifants River. You are allowed to get out of your vehicle on the bridge, providing you stay between the designated lines. The view is breathtaking and more often than not you will see some animals and birds from here, including elephants.
Yellow-billed kites can often be seen hunting overhead and have a habit of sitting on the bridge railing for a rest every now and then.
