I would say it depends on whether it is public or private. Private, no question Colorado Golf Club and then behind that is Pradera and The Pinery on the private side. Public...actually Black Bear used to be public but is moving to private with the Canongate company but that is an excellent course if you can get on early. Otherwise, it is a long round because of the course layout.
There are three to choose from. Canterberry Crossing has the Black Bear course which is public. The newest course is Colorado Golf Club located southeast of Parker, which is private. Pradera is a private course located between Parker and Castle Rock.
