4th Annual Tri-Cities Earth Day at the REACH
Join the REACH Museum, Sustainable Tri-Cities, and Citizens’ Climate Education for Tri-Cities Earth Day 2026, a free, family-friendly community celebration focused on conservation, education, and local action.
Now entering its fourth year, Tri-Cities Earth Day brings together 750+ community members, local nonprofits, educators, scientists, artists, and sustainability organizations for an afternoon of hands-on learning and connection. Visitors can explore interactive exhibits, meet regional organizations working on environmental and climate solutions, enjoy live performances, and participate in earth-inspired art and activities designed for all ages.
Earth Day at the REACH Museum highlights the unique environment of the Mid-Columbia River region and empowers families, students, and community members to take meaningful action—both locally and at home.
