250 Actions
Montgomery County GreenFest is going big in 2026! To honor the 250th anniversary of Montgomery County (founded in 1776), this year’s theme centers on legacy and collective action. We invite every resident to celebrate Montgomery County’s 250 years by committing to 250 actions that safeguard our environment and public health. What actions will you take?
Happening at Greenfest
This year’s celebration features live music from Los Nuevos Diablos, engaging exhibits from local nonprofits and watershed groups, and plenty of sustainable shopping opportunities. Visit the 250 actions booth! We are collecting batteries, gently used clothing and art supplies.
