On April 25, 1925, the tradition of golf in the country near the City of Chino began in the beautiful Chino Hills at the Los Serranos Country Club. In the beginning, the club was a semi-private seven hundred and fifty acre recreational community and resort providing golf, stables and riding trails, swimming, trap shooting, boating, fishing, polo grounds, a private landing strip, rental cottages and wonderful country home sites. The golf course was designed by internationally known Golf Architect, John Duncan Dunn.

The story of today's Los Serranos Golf And Country Club begins some two hundred years ago, when bands of Indians roamed the fertile valley and hunted an ample supply of game. In the early 1800's the land became part of the vast San Gabriel Mission, and was used to graze horses and cattle belonging to the Mission.
