The term 'Walk in a Garden' can be summarized by the four-letter word 'PATH'. A PATH is a route or course of travel, usually through a garden. It is often made of stone, gravel, or other materials and is used to provide a way for people to walk through a garden. Paths can also be used to create a sense of direction and structure within a garden. They can be winding or straight, and can be used to lead visitors to different areas of the garden.
