Un Mar de Colores · Ocean Beach, CA
Indigenous Kumeyaay relationship with water woven into hydrology fundamentals — not erased from science curriculum.
Un Mar de Colores's Watershed Explorers program brings Ocean Beach youth into the full watershed-to-ocean story of San Diego County. Day trips and overnight summer cohorts trace mountain streams from Cuyamaca State Park to the coast, including your own Ocean Beach beaches. We partner with San Diego Unified School District and community organizations including OB Town Council and San Diego River Park Foundation to recruit from Ocean Beach Elementary, Dana Middle School. Every program integrates the Tijuana River watershed case study — the only cross-border river in Southern California.

Ocean Beach's OB Pier and Dog Beach locations offer our Point Loma peninsula cohorts direct-access surf instruction. The San Diego River mouth at Dog Beach provides paddle-flat-water training, and our Ocean Beach Elementary and Dana Middle partnerships anchor our youth recruitment across the 92107 zip code — one of San Diego's most culturally diverse beach neighborhoods.
Watershed-to-ocean tracing answers why Ocean Beach storm drains matter — runoff pipelines taught from street to OB Pier, Dog Beach (Ocean Beach).
Parents searching watershed education near Ocean Beach, CA find paid eco-camps first. Un Mar is different: BIPOC-led nonprofit programming with Tijuana River cross-border case study, Kumeyaay water perspectives, and Title I school partnerships — not generic nature camp marketing.
Ocean Beach sits inside San Diego County's coastal equity gap — 39% 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.
When we say free for Ocean Beach youth, we mean wetsuits, soft-tops, rashguards, sunscreen, transportation, and instruction — the full stack commercial programs charge $50–$150 per session for.

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.
We do not charge families. Ever. That policy is structural — grants, donors, and shop revenue fund access so Ocean Beach youth are never waitlisted for inability to pay.

Primary water sessions run at OB Pier. We also use Dog Beach (Ocean Beach) for skill progression. Classroom components happen at OB Town Council and other partner sites. All water activities happen within lifeguard-flag zones.

Three ways: (1) everything is free, while most Ocean Beach surf programs charge $50–$150 per lesson; (2) we are BIPOC-led and our coaches reflect the 39%-BIPOC Ocean 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 Ocean Beach, not just those who can afford access.
