Diamond Trail Golf Club was established in 1997. The course architect was Lowell Erdman. The golf course was completed and ready for play in the summer of 1998. We have concrete cart paths the entire length of the course as well as watered fairways. Check out our picture gallery to see our score card, course layout and other photos. Come play our unique, 9 hole golf course that is tucked in the rolling hills of Lynnville. Some say it's the "best kept secret in Iowa!" Help us share our secret!
