Winter Layout effective 12/14/22 - Baskets #1, 2, 3, 4, 5, 11, 16, 17, 18 get removed for winter and a 9 hole safari layout is available for play Ellison is the most popular/crowded course in Rochester. The 18 hole course is available for play from mid April till early October as many of the baskets are removed for the winter sledding hill. Almost every hole is reachable without pro distance. It is usually very well maintained, although 13-15 are usually damp year-round. There are no water hazards and it’s rare to lose a disc on this course. The signature hole 12 is 500 feet, but downhill and wide open.
