(KRON) — While the origins of 4/20 have been contested, one theory is that it started right here in the Bay Area when a group of high school students in San Rafael would gather to smoke together at 4:20 p.m. For this, among others, reasons, 4/20 remains close to many Bay Area locals’ hearts.

If you’re looking to celebrate, here are some events around San Francisco.

Hippie Hill

First mention goes to the annual Hippie Hill celebration at Robin Williams Meadow in Golden Gate Park. Festivities kick off on Thursday at 10 a.m. and run until 5 p.m. and are completely free.

This year’s event will feature live music, on-site cannabis dispensaries and food and beverages.

Patrons can enter on John F Kennedy Drive and Kezar Drive or Martin Luther King Jr Drive between Bowling Green Drive and Kezar Drive.

See the full schedule online.

Keep the party going at the Midway with the “Official Hippie Hill After Party” featuring DJ Lo Down Loretta Brown, Talib Kweli DJ Set and DJ Shortkut. Doors open at 8 p.m. at 900 Marin Street in San Francisco.
