Abstract: A simple, brightly colored, plastic collar is disclosed for greatly enhancing the visibility of the golf hole for players, spectator and televised golf events. The collar has a diameter essentially the same as a regulation hole and is installed in the cup adjacent the exposed earth wall between the lip of the hole and the hole liner. Furthermore, use of the collar enhances a retention of moisture in the earth around the lip to prevent drying and crumbling of the soil which can cause an initially sharp lip to become rounded. The collar preferably has thinner upper perimeter wall to insure that the reaction of an impinging golf ball against the cup wall having the collar installed is not substantially altered from the reaction of a ball impinging an earth surface of a cup not having the collar installed.
