As mentioned, the course is open year around for anyone to play day or night for no fee. The number of holes to be played will be limited to the time of year (36 holes in spring and summer; nine in the fall and winter). The Green Golfer's Hut, located across from the Golf Tavern on Wright's Street, displays the rules of the game as well as a detachable paper maps for the course. There are also placards located along the southern pedestrian walkway that give the history and illustrate the location of the holes.
