A golf course consists of a series of holes, each consisting of a teeing ground, fairway, rough and other hazards, and a green with a flagstick (pin) and cup, all designed for the game of golf. A standard round of golf consists of playing 18 holes, thus most golf courses have this number of holes. Some, however, only have nine holes and the course is played twice per round, while others have 27 or 36 and choose two groups of nine holes at a time for novelty and maintenance reasons. Additionally, par-3 courses also exist, consisting of nine or 18 holes, all of which are a Par 3. Many older golf courses, often coastal, are golf links, of a different style to others. For non-municipal courses, there is usually a golf club based at each course, and may include a pro shop.
