George Strath was appointed in 1881 as the club's first golf professional,[5] and together with 1882 Open champion Willie Fernie, designed the original course, expanding it to 18 holes by 1888.

[6] The two were assisted by Charlie Hunter, greenskeeper of the neighbouring Prestwick Golf Club, in Troon's formative years.

[7] When Strath left the club's employ in 1887, Fernie became head professional, and served in that role until his death in 1924.

Glasgow Prestwick Airport is located slightly to the south and east of the club, and low-flying aircraft are nearest its southern section.

[9] Its clubhouse, designed by Henry Edward Clifford and built in 1886,[10] is richly decorated with historical golf artifacts.

This opening section offers full visibility and plenty of space, but does still require accuracy to avoid deep bunkers.

Beginning with the seventh, the Old Course turns further inland, while simultaneously changing direction, on each of its next six holes, among hillier dunes and thicker vegetation, including ulex (commonly known as gorse, furze, or whin), to severely punish offline shots.

This sector, with two blind tee shots on the tenth and 11th, marks a sharp rise in difficulty from the opening holes.

With the 13th hole, the player turns northwards for a long, very stern finish, running parallel to the opening stretch.

The club is private; guests are allowed at certain times, under advance booking, with a handicap certificate establishing proficiency.
