The Watershed Explorers program is Un Mar de Colores's flagship environmental education offering. Summer overnight cohorts trace the journey from Cuyamaca Rancho State Park's mountain streams to the San Diego coast, with special focus on the Tijuana River watershed — California's most cross-border and pollution-impacted river system. Curriculum integrates hydrology fundamentals, Indigenous Kumeyaay perspectives on water, and California coastal policy. Year-round day trips serve school field-trip groups across our 15+ Title I partner schools, and all programming is free with transportation included.

This hub connects San Diego County families to watershed education across 27 cities. Every city link below is a full local page with beaches, school partners, and enrollment paths — not an empty gateway.
