The original links courses, which are mostly found in the U.K., were situated in the thin strip of sand, grass and dunes that lay between the sea and agricultural land. The courses "linked" them together. Links style courses will have undulating fairways, sand dunes, deep bunkers and few (if any) trees. Many of the most famous links courses are to be found in Scotland or Ireland, including St Andrews, Turnberry, Portmarnock and Ballybunion.
Executive courses are the Mini-Me's of golf courses. An executive golf course is comprised of many par-3s plus a small number of par-4s and/or par-5s so that it is much shorter and has a much lower par (often in the upper 50s to low 60s) than a regular course.
An executive course is designed to be played quickly by the player who does not have a lot of time. They are great options for beginners and juniors, or anyone who enjoys golf but struggles with the length of standard golf courses. Many executive courses are nine holes in length.
