Denver Shroom Fest, a celebration of psychedelic mushroom culture, will not go on as planned in 2025.

On Thursday, organizers announced the second annual event, which was scheduled for June 15, has been cancelled due to “unforeseen circumstances and some bad luck.” Co-founder Jonathan Cherkoss suggested the festival may not return in future years either.

“Denver Shroom Fest was a huge success, and collaborating with Colorado’s vibrant mushroom community was an incredible experience. Though a sequel may not be in the cards, stay tuned for more psychedelic events in the future,” Cherkoss said in a statement emailed to The Denver Post.

Denver Shroom Fest was preparing to welcome psychedelic enthusiasts, mushroom growers and more back to ReelWorks in RiNo after a successful inaugural year.

In 2024, the event marked something of a coming-above-ground party for the local psychedelics community. There were educational talks, live music and free samples of mushroom products — all possible because psilocybin is now decriminalized in Colorado.

If Denver Shroom Fest had happened on June 15, it would have taken place around the same time as Psychedelic Science, a massive conference focused on research, policy, and business, coming to the Colorado Convention Center from June 16 to 20.
