Game viewing can be very productive on this main tar road between Numbi Gate, Pretoriuskop and Skukuza.
Where the H1-1 branches off the H2-1 near Pretoriuskop the vegetation is typical of the sourveld area; tall grass with silver cluster-leaf and marula trees.
Further east the vegetation opens up completely in the vicinity of Shitlave Dam and the short detour to the dam is well worth while for waterbuck, kudu, baboons, hippos, elephant and even the eland, an antelope that is usually hard to find.
The central part of this route runs through broad-leaved vegetation and is generally quiet in terms of game-viewing although the occasional wild dog pack has been sighted. For buffalo sightings take the short S11 sand road past Napi Boulders.
Still further east you will find the turn-off to Transport (Vervoer) Dam, another detour worth taking, especially early in the morning. Here you can expect to see elephant, buffalo, lions and white rhino. On a good day you may spot four of the Big Five with the exception of the leopard, which is difficult to find at most times.
As you approach Skukuza the vegetation changes again and the road runs through a few very scenic koppies with massive boulders. This is good for spotting some of the predators such as spotted hyaenas, lion and if you're lucky the evasive, leopard.
From here to Skukuza the vegetation becomes relatively dense and consists of fine-leaved acacia-veld which is very scenic. Early mornings and late afternoons can produce wild dog, lion and even leopard sightings.
The H1-1 is 55 kilometers (34 miles) long.
