If you look closely across the valley from this spot, you can see a few buildings at Gilroy Yamato Hot Springs, though the big hotel pictured above is long-gone. GHS is now part of Henry Coe State Park.There's quite a bit of history here, but unfortunately it's currently off-limits to the public due to vandalism, lack of money, etc.
It has been designated as California State Historical Landmark #1017. Gilroy Hot Springs was a local landmark and gathering spot for a long time up until the Depression when business declined. In 1938 a Japanese-American family purchased it and after the war they opened their doors to dislocated families after the internment camps were closed.

If you want to help out and see the area, you might consider volunteering with a small organization, Friends of Gilroy Hot Springs, who has work parties to stabilize and preserve the area until it can be reopened. visit link
