420 is coming and your friends are going to start asking where you’ll be on the big holiday. For the 3rd year in a row, David Downs and crew are answering that question with Space Walk, a citywide Cannabis celebration that will take over San Francisco for an entire week.
Downs says he wants Space Walk, as well as his other events Hash Week and Terpnami, to be the kind of moments that bring people into SF to experience the vibrant feel of the Bay. “Every week is weed week for cannabis lovers, but we turn San Francisco up a notch for April 20,” Downs said proudly.

When the event first began in 2024, Downs told us that even though the city’s famous Hippie Hill celebration had ended, he wanted to prove that Cannabis culture is alive and well on the streets of San Francisco by doing something that brought together people and players from inside and outside the industry and promoted the idea of cannabis tourism.
Downs has organized the type of experience that invites stoners to a celebration in the city while also connecting culture with commerce. To this point, SF Space Walk creates moments where stoners can meet with farmers face-to-face but also there are community events for anyone who just wants to celebrate. This year Space Walk adds a club party, video game tournament, film night, food collabs, and heady book giveaways to the list of events.

Along with this comes the return of Downs’ Get To The Bag, a travelling gallery show dedicated to the art of modern weed packaging. This 1,800-piece exhibit spans three decades and three continents, giving West Coasters a chance to get up close and personal with some of the extravagant trap packaging that you’ve seen on social media.
