Marijuana has been legal in Colorado for almost 5 years now and we declare this holiday as a celebration of Cannabis Culture. The Mile High 420 Festival is the World’s Largest Free 420 Celebration in Denver’s Civic Center Park.

Nope. This event is free, there is an Eventbrite for people to RSVP. No tickets will be collected at the gates. The RSVP system is so we can communicate with attendees.

We recommend public transportation or ride sharing service as parking is limited downtown and several area streets will be closed. Check latest map for a list of entrances.

The festival will be open 2pm – 8pm with music, vendors and activities all day.

The festival is under new management and is no longer a Rally. 2018 & 2109 were a great successes and the same team is excited to once again produce the World’s Largest Free 420 Celebration. We will have live music from both international and local bands, amazing vendors, leaders in the cannabis industry and much more. Expect dozens of Denver’s finest food trucks, cannabis craft vendors, and over 20 local charities.
