Colonial Golf Course sits in the flat, open terrain of Sandoval, Illinois, where prevailing southwest winds sweep across the fairways. The front nine is anchored by a long par-four that doglegs left around a pond, while the back nine introduces a short par-three over water to a narrow green guarded by two bunkers. A drainage canal crosses the 13th fairway at a diagonal, forcing players to choose between laying up short or carrying the hazard. Mature pin oaks line several landing areas, and the course’s irrigation system feeds bentgrass greens that roll consistently once the afternoon sun has dried morning dew. The clubhouse, a low brick structure with a metal roof, faces the 18th green, where a slight crown in the putting surface often sends approaches toward the left fringe.
