Tennis enthusiasts have four courts at their disposal at the Grünfeld Tennis Centre. The special floor covering here enables games to be played as if they are taking place on a clay surface. The completely renovated all-weather exterior courts, Swissflex covering and synthetic turf are ideal for playing tennis out in the open. Players and spectators can let themselves be spoilt in the lovely clubhouse. The Rapperswil-Jona Tennis Club maintains five clay courts and is near to the city centre and lake. A further five clay courts with magnificent views are located at the Lenggis tennis club. Both tennis clubs have a cosy clubhouse that is ideal for relaxing after training or an exciting match.
