No. Hitler never was in South Africa but if it were up to a couple of Bloemfontein Germans, he would have been. The cache takes you to Somerton. Property was purchased in this area and a house developed by some enthusiasts to bring Hitler over should he lose the war and be exciled from Germany.
The history of the area is also fraught with tales of ghosts and was a prominant stop on the now defunct Bloemfontein Ghost Tours. Older residents may also remember the house's use as Sun Sets, a club which sparked outrage for its excessive late night noise in the otherwise tranquil area.
The cache itself is not on any of the properties as they are now privately owned.
