The Sacramento River Delta is a premier location for flat water windsurfing located only an hour from San Francisco. An Ebb tide builds up ramps for jumping, making it a fantastic Freestyle and Racing venue. Rio Vista is also one of the most diversely represented locations on tour, including a high number of entries in the Youth bracket. Registration and more info can be found at the official Rio Vista Grandslam website.
