Belgium was fertile ground in the pre-war years for England's Tom Simpson. Though overshadowed by Harry S. Colt, he was a designer in much the same mold, in that he immersed his courses in the landscape rather than imposed his designs on it. He was most active in the 1930s, when he made significant alterations to Colt's New Course at Sunningdale, so his course at Spa is often called the Sunningdale of the Continent; this early layout made the most of the stunning rolling countryside. Each bunker is carefully placed and great use is made of the natural features. All hazards are clearly marked, so the course's main defense is the subtlety of its greens. The only drawback is a clay base that can make things slow and soggy after rain. July is a good month to visit for nearby attractions like concerts at Francofolies and Belgium's premier car racing track.
