A new report shows three of the Bay Area's national parks generated almost a half billion dollars in visitor spending last year.  

Chief among them was the Golden Gate National Recreation Area, drawing almost $300 million from visitors.

Muir Woods and Point Reyes National Seashore also brought heavy tourist spending.  

In the town of Point Reyes Station, Michael Zilber with the Cowgirl Creamery says this cheese shop benefits from being near the national park.

"The idea was to service those visitors and in doing so really grow an appreciation not only of the park but of the great agricultural history of the area too," Zilber said.

A spokesman for Point Reyes says it's unclear exactly how the federal spending cuts that could come down today would affect the park.
