Mycelium is a three-day festival for sustainable action in Basel and will take place from August 14 to 16, 2026. Workshops, guided tours, concerts, and space for creative reflection—for everyone and free of charge!

At Mycelium, we explore ways to lead a responsible life. We want to try to breathe new life and meaning into the concept of sustainability and restore some of its true identity and significance, which affects us all: a guiding principle for making societies future-proof and addressing today’s problems.

This year’s theme is “Care and Concern”: What do you care about? What worries you? Between care and worry, we’ll explore how we can work together to build a better world and live sustainably. Will you join us?
