Superlatives seem inadequate to describe the wonders of Spa-Francorchamps, the greatest modern motor racing circuit in the world.

This roller-coaster track courses along the contours of the Ardennes mountains with a beautiful natural flow.

It contains every conceivable challenge a Grand Prix driver could wish for and probably the world's toughest corner.

Eau Rouge's glory, neutered a little in recent years, should be restored by rule changes reducing grip in 2008.
