Your guide to 4/20 events in Denver

From music festivals to cannabis-infused yoga brunches, here’s your guide to 4/20 in Denver

Denver’s week-long celebration of 4/20 dips a toe into nearly every aspect of Colorado’s culture.

As the state’s cannabis industry grows, so do the size and scope of its events. From concerts to food festivals and high society soirées, here is your definitive guide to 4/20 events in Denver for 2018.

Concerts and Music Festivals

4/20 weekend at Red Rocks Amphitheatre – April 19-21

Instead of one evening of celebratory music, Red Rocks has blessed Colorado with three heady nights. On April 19, the historic venue hosts 311, Method Man & Redman presented by local dispensary LivWell Enlightened Health (the classic stoner duo also headlines Cervantes the following night). On April 20, see Flosstradamus, followed by Opuio + SYZYGY Orchesta and Sunsquabi on April 21.

UPDATE: Due to rain, Flosstradamus at Red Rocks on April 20, 2018 has been moved to The Fillmore Auditorium.

Melissa Etheridge at the International Church of Cannabis – April 20

This free (hooray), non-consumption (boo) event will feature a discussion called “The Cannabis Connection” from legendary LGBTQ, cannabis advocate and cancer survivor Melissa Etheridge. Etheridge will tell her “survival stories” alongside a soundtrack, which leaves a bit of mystery to the amount of music she will play for the crowd to accompany to her stories. Ron English will also be speaking at the event which begins at 5:30 p.m. on April 20, 2018, at the International Church of Cannabis 400 South Logan Street in Denver. While it is free, organizers warn there is limited seating so you must sign up here.

Mile High 420 Festival – April 20

This year, Civic Center Park tries to capture some of its legendary magic for the 4/20 holiday with new sponsors and a new vibe (as more of a celebration instead of a protest).

Find out more about the free event, including an entire list of musical acts and more on the controversy leading up to it, here.
