Lots of walk on courts, but you can book online if you have a NYC tennis permit.
Best courts on Manhattan.
Almost like playing in Paris.
The ten clay courts at West 96th Street near the Hudson River Greenway offer beautiful views of the Hudson River and the surrounding gardens. Click on the link to reserve a court during tennis season.
An excellent picnic spot. On sunny weekends, you'll find families on the grass nearby, enjoying the views and the weather
