Rough (golf)

A golf course is the grounds where the game of golf is played. It comprises a series of holes, each consisting of a teeing ground, a fairway, the rough and other hazards, and a green with a flagstick ("pin") and hole ("cup"). A standard round of golf consists of 18 holes. Most courses contain 18 holes; some share fairways or greens, and a subset has nine holes, played twice per round. Par-3 courses consist of nine or 18 holes all of which have a par of three strokes.

Many older courses are links, often coastal. Courses are private, public, and municipally owned, and typically feature a pro shop. Many private courses are found at country clubs.

Etiquette is very important on Golf courses.

Although a specialty within landscape design or landscape architecture, golf course architecture is considered a separate field of study. Some golf course architects become celebrities in their own right, such as Robert Trent Jones, Jr.; others are professional golfers of high standing and demonstrated appreciation for golf course composition, such as Jack Nicklaus. The field is partially represented by the American Society of Golf Course Architects, the European Institute of Golf Course Architects, and the Society of Australian Golf Course Architects, though many of the finest golf course architects in the world choose not to become members of any such group, as associations of architects are not government-sanctioned licensing bodies, but private groups. While golf courses often follow the original landscape, some modification is unavoidable. This is increasingly the case as new courses are more likely to be sited on less optimal land. Bunkers and sand traps are almost always artificial, although other hazards may be natural.
