Sporting activities are well catered for on Thesen Islands.
There are two all-weather tennis courts lit by powerful floodlights for those balmy summer evenings. They are sunken below ground level to minimise the impact of the daytime coastal breezes. One of the courts has been converted to a multipurpose court which is not only used for tennis but also features a basketball net. A squash court is in the adjacent building, with viewing and change facilities on site.
An 18 hole putting green has been constructed on the south-eastern tip of Plantation Island. This is a fun course with wonderful vistas of the estuary and the famous Knysna Heads. Permanent volleyball posts have been installed on the Main Beach opposite the Clubhouse; the net and ball can be collected from the Clubhouse during office hours. There is also a cricket practice net next to the clubhouse.
The most recent additions to the sporting facilities on Thesen Islands include an outdoor gym and two 5km jogging/walking routes (clean takkie and dirty ‘takkie’ routes). Yoga classes are hosted at the Clubhouse. The style is flow yoga, based on Ashtanga principles but also incorporating strengthening and core-work poses.
