Golden Gate Park’s Hippie Hill, known for its pungent and pervading aroma of marijuana, won’t be nearly as green this 4/20.

The cannabis holiday — which falls on Monday — is an exalted day for pot enthusiasts. But this year, the coronavirus has upended traditional celebrations that typically draw thousands of smoky revelers to the famous San Francisco knoll.

In response to the city’s stay-at-home orders, the organizers of the 420 Hippie Hill festival announced last week they were canceling the event. In past years, tens of thousands of people packed Robin Williams Meadow to pay homage to the cannabis plant with music, merchandise and food, a tradition organizers say dates back to the 1970s.
