KCBS_740 SAN FRANCISCO (KCBS) — The Bay Area’s eleven National Parks sites are more popular than ever, and the result is more tourist dollars being directed into Bay Area communities and businesses.

A new report found that tourism at attractions like Alcatraz, and Muir Woods are on the increase. Alcatraz alone hosts over 1.5 million visitors per year.

The Park Service estimated that their sites pump more than $1 billion into the Bay Area’s economy.

Stinson Beach, Muir Woods, and Point Reyes National Parks bring in half of that $1 billion alone, according to the Park Service.

“All those national park sites draw people to areas in the Bay Area, and when they are there, they’re buying lunch, they’re buying gasoline, they’re renting cars, they’re in hotel rooms, they’re buying trinkets, things to remember their trip by,” Pickavet said.
