Designed by golf course architects Alister MacKenzie and Perry Maxwell in 1929, the par-70, course offers views of Lake Michigan and Crystal Lake. The Sleeping Bear Dunes National Lakeshore lies just to its east. Despite being consistently ranked among the top courses in the United States (ranked 10th for 2007–08 by Golf Digest) the only tournament of note it has hosted has been the 1991 U.S. Senior Amateur, due to its location far from population centers and the corresponding lack of sufficient facilities (lodging, transportation, infrastructure) needed to accommodate the crowds attracted by major tournament events. Crystal Downs is currently ranked the #19 course in the world according to Golf.com.
