4/20 events in Boulder

The Best 4/20 Events in Boulder


April 20. For some, just another day. For Boulderites who like to relax with a little weed, it can be one of the biggest celebrations of the year.

Colorado has always had a strong culture surrounding this controversial plant, and as one of the first states to legalize its use, it holds a special place in our hearts. This is why we take one day each year to celebrate the plant and the culture.

Here are the best events in Boulder, Denver and the surrounding areas to celebrate 4/20.


CU-Boulder: While this is not an official event and is not supported by the university, it is a tradition for students to meet on Norlin Quad to light up at 4:20 p.m. on 4/20. This has been going on for years, and it became so big that campus started fully closing, pre-legalization. The campus has started staying open on 4/20 now, and if you need a casual place to celebrate the day, this is a great spot.

Live music: If you think weed goes well with concerts, you can almost always catch live music on April 20 at Boulder’s bigger stages, such as the Fox Theatre and Boulder Theater.

For 2019, Escort is playing at 8:30 p.m. at the Boulder Theater in downtown. Brownies and Lemonade goes on at 9 p.m. at the Fox.

Mile High 420 Festival: The Mile High 420 Festival, located at the Civic Center Park in Denver, is a full-day event, running from 10 a.m.-7 p.m. on 4/20. The event offers big musical acts that in the past have included the likes of Lil Wayne, Lil Jon, The Original Wailers, Inner Circle, Taylor Alexander and bluegrass band WhiteWater Ramble. In the past, there have  also been multiple time slots focused on yoga, fitness and comedy. Multiple food, craft and cannabis vendors round out this event, making it the biggest 4/20-themed, one-day festival in Denver. It draws more than 50,000 people. The best part? The festival is completely free to attend.
