It's not in Gilroy, but a bit further north is Andy's Orchards in Morgan Hill. The 101 is a proper freeway at this point, so you must exit the freeway at Cochrane and turn east, then right on Mission View Drive, and then follow the signs. They place out several varieties of cherries, and then later in the year, many varieties of other stone fruits. Apologies if Andy's has been posted about before, but they're quite close to Gilroy and in my opinion, better. In fact, I have to get myself over there and see if the newest crop is ready to buy.
