Twenty Valley Golf & Country Club opened as a nine-hole course in 1959, with the final nine being added in 1967. Spread over 142 acres in the Niagara Peninsula, renowned golf course architect Clinton E. “Robbie” Robinson designed Twenty Valley. The Fall 2007 issue of Ontario Golf Magazine had a feature article on “Robbie” Robinson, titled The Forgotten Master. In 2007, “Robbie” was inducted into the Ontario Golf Hall of Fame.
Twenty Valley has hosted some prestigious championships over the years. In 1988, it played host to a Canadian tour event called the TPD Championship. In the 50th anniversary year of the club, it hosted the 2009 Ontario Senior Men's Championships and has since also hosted the 2012 Ontario Senior Women's Championships. Twenty Valley also played host to the 2009 and 2012 OFSAA Boys Golf Championships.
The golf course has held its own over the years with competitive golfers struggling to post low scores over the challenging layout. The current course record is held by Rick Todd. Rick opened up the 1988 TPD Championships with a 63 which beat the previous record by one shot set the previous day by life member and Ontario Golf Hall of Fame inductee, Ken Tarling, in the pro am.
The score of 63 has since been matched on two occasions from the member's tees during Thursday night competition. First in 1989 by former member and club champion, Tim Hasenack and most recently by long time member and multiple club champion, Bill Lipsett in 1997.
