Pacific Beach sits between Mission Bay and the open Pacific, producing the mellowest learner waves in the city. Tourmaline Surfing Park — designated a surf-only beach in 1981 — is the safest and most instructor-friendly break in San Diego. Over 55% of students at Mission Beach Elementary, Pacific Beach Middle, and Mission Bay High qualify for free or reduced meals, making this one of our highest-impact urban partnerships.

Kumeyaay relationship with water in watershed curriculum centers Indigenous science for Pacific Beach Latino and Indigenous youth — not token land acknowledgments without hydrology depth.
Pacific Beach's relationship to the Pacific is complicated by history and economics. Our curriculum weaves Kumeyaay coastal stewardship, environmental justice, and culturally grounded instruction into every session — not as an add-on, but as the foundation.
Pacific Beach sits inside San Diego County's coastal equity gap — 44% of residents identify as BIPOC, yet beach access has historically been gated by cost, transportation, and culture. Un Mar de Colores closes that gap with free programming and school-based recruitment.

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.
Program safety is documented: lifeguard coordination, 4:1 ratios on youth water days, trauma-informed staff training, and parent communication protocols in English and Spanish.

Three ways: (1) everything is free, while most Pacific Beach surf programs charge $50–$150 per lesson; (2) we are BIPOC-led and our coaches reflect the 44%-BIPOC Pacific Beach community we serve; (3) our curriculum includes environmental justice, Kumeyaay coastal history, and cultural arts — not just surf skills. We exist because the ocean should belong to everyone in Pacific Beach, not just those who can afford access.
