Mark your calendars for the 13th Annual Earth Day San Marcos Festival, returning to Spring Lake on Saturday, April 18, 2026, from 10 a.m. to 4 p.m.! This year’s theme, “One Heart, Many Waters,” highlights the powerful connections between our community, our water, and the ecosystems that sustain us.

This free, family-friendly event offers a day of celebration, discovery, and connection at the headwaters of the San Marcos River. Enjoy hands-on activities, live performances, demonstrations, and interactive experiences, and connect with eco-focused exhibitors, local organizations, and vendors.

We can't wait to see you there!
