Earth Day Mill Valley 2024

We had a wonderful time at Earth Day Mill Valley, our free community event at the Mill Valley Community Center on Sunday, April 21, 2024, from 11am to 2pm.
Earth Day Mill Valley featured fun activities for all ages, climate action exhibits, art. music — and free ice cream! Over 50 green booths engaged visitors to help build a more just and sustainable world.

Participants learned to live sustainably, use clean energy and transportation, green up their homes and gardens, eat healthy food, protect nature, and build resilient communities.
Our event brought together a diverse community of parents, youth, seniors, environmentalists, green businesses, climate action groups, educators, artists from across Marin and the Bay Area. 
Participants of all ages seemed to share a positive vision for living sustainably and creating a better world. We learned a lot from each other and made new friends!
Earth Day Mill Valley was organized by Mill Valley Recreation – in collaboration with Green Change, which received support from the County of Marin, Marin Community Foundation, and MCE.
