Eldorado is located south of Lansing off 127 on the northwest side of Mason with 27 holes.

The terrain is slightly rolling, with narrow and open fairways bordered by woodlands, water hazards, and sand traps with moderate-sized, round, or kidney-shaped greens. The layout has three nines (Red, White & Blue), and each presents a similar length and challenge: Red/White - 70.2/123, course/slope ratings at 6,385 yards from the tips; White/Blue - 71.2/123, at 6,494 yards; Blue/Red - 71.6/123 at 6,707 yards, originally designed by Bruce Matthews in 1966 and redesigned by Jerry Matthews in 1996.
