golf course 9-hole design

Quick answer：

The 9-hole design of a golf course refers to a layout that includes nine holes for players to complete a round of golf. This design is often chosen for its compact size and ease of maintenance. Each hole in a 9-hole course is typically a unique challenge, varying in length and difficulty. These courses are popular for private clubs, public courses with limited space, and as part of larger 18-hole facilities.
