A golf course by the sea is a type of golf course that is located near a body of water, such as an ocean, lake, or river. The term 'links' is used to describe this type of golf course, as it is derived from the Old English word hlinc, which means 'rising ground or ridge'. Links courses are typically characterized by their sandy soil, undulating terrain, and natural hazards such as sand dunes, bunkers, and water hazards.
