Welcome to 3rd Ave!

3rd Avenue is a kiteboarding/sailboarding site on the San Francisco bay. You should be able to tell from the various "signs" whether or not to get yourself over to 3rd, one of the best kiteboarding sites anywhere. Visit the home of our permanent webcam and weather instrument host, Gilead Sciences, by selecting the image at the top of this page. Gilead Sciences is headquartered in Foster City. Special thanks to John Kennedy and Andrew Smith for direct assistance in helping to get the equipment functional again and for the purchase of our new Axis HD cameratheir support with the weather instrument.

  • There are 30 parking slots at the Mariners Point Golf Course, along the fence facing the bay. There is an entrance through the fence at the east end of this set of parking spaces. Please do not park anywhere else in the lot as those spots are reseved for golfers. Also, make sure to keep the golf course area clean as we are guests and not paying customers. You will find bathrooms at the golf course, but you might patronize them by buying some food in their concession.
