Mercer Island Country Club (Outdoor)

Members reserve online via mercerislandcc.com.

Private member club — membership required for all court access.

Usually busiest weekday evenings (roughly 4–8pm) and weekend mornings (9am–1pm); quietest weekday mornings before 7am and after about 10pm. At that time, expect it to be hard to get a court — an off-peak window will be easier. It has no lights, so it's effectively closed to walk-up play after dark. This is a projection from time of day, day of week, and court size — not live occupancy.

Private club outdoor courts. Indoor courts tracked separately.
