Earth Day Marin 2026
Thanks to all of you who joined us at Earth Day Marin in Mill Valley last April! 🌍
Earth Day Marin 2026 brought together over 600 people of all ages for an inspiring day of action and connection. Our 5th annual environmental celebration took place on the lawn behind the Mill Valley Community Center on Sunday, April 26, 2026, from 12 to 3pm, hosting climate and democracy champions from across Marin and the Bay Area.
From Aztec dancers and zydeco music to green booths, fun activities, inspiring youth, creativity, democracy and more — Earth Day Marin was a really special gathering for our community. We had a wonderful time celebrating our beautiful planet with friends and neighbors, playing and learning from each other.
To relive the joy and energy we shared together, watch our video memory — and see photos and videos of last year’s festival. If you missed the event, this is your chance to see what the buzz was about. To learn what we accomplished together, be sure to read our impact report. We left feeling hopeful, connected — and ready to change the world. Thanks to everyone who made this day so special! 💚
