Guide to Halloween EDM Events in Denver

Colorado has a long history of going batshit crazy for Halloween festivities. There are massive costume parties all over town and plenty of EDM music to keep you popping through Dia de Los Muertos. You can peruse our calendar of Halloween events to catch artists like Sub Focus on 10/30 at Red Rocks and then Cloonee headlining at Mission in Denver on Halloween night.

Halloween in the Rocky Mountains

If you're going for a Halloween festival-vibe, Supernatural Denver brings top artists to Mile High City each year. While you'll find no shortage of all-hallows-eve concerts in the Denver metro, you might try your cards further into the mountains instead; Drive to Frisco for Maddy O'Neal's Halloween costume party or venture to Aspen for Halloween night with Opiuo. Best dress (in)appropriately for potentially chilly nights in the mountains the week of Halloween in Colorado.
