Free Ocean Stewardship for BIPOC youth in San Marcos, California — Un Mar de Colores

Un Mar de Colores · San Marcos, CA

Environmental Justice on the Coast — Free in San Marcos

Commercial eco-tourism charges for 'volunteer' beach days. Un Mar charges nothing — ever.

Un Mar de Colores hosts ongoing Ocean Stewardship cleanup and conservation programming across the San Marcos area and surrounding coast. Monthly events combine hands-on beach cleanup with environmental justice education, citizen science data collection, and policy literacy. Our San Marcos programming partners with California State University San Marcos (student volunteers), San Marcos Unified School District, Boys & Girls Club of San Marcos, and all events are free and family-friendly.

Schedule — San Marcos Program Days

Monthly cleanups, quarterly workshops · Completely free

You Might Be Feeling This

  • Transportation to monthly cleanups from inland San Marcos (11 miles inland) feels like another unpaid logistics burden.
  • Eco-volunteer events near the coast feel white-dominated — your family doesn't see themselves in the lineup of volunteers.
  • One-off Earth Day events don't build continuity — you want monthly action with the same community.

What Changes When Youth Get in the Water

  • BIPOC-led movement — stewardship led by communities historically excluded from coastal conservation spaces.
  • Quarterly workshops deepen advocacy and community organizing beyond monthly cleanups.
  • Monthly beach cleanups across San Diego County — consistent action, not one Earth Day photo op.

Why San Marcos Matters to Our Mission

From San Marcos's Title I schools to the sand, our pipeline is built on real partnerships — not generic 'serving the area' language. Every cohort names the schools, beaches, and community orgs involved.

With 96,664 residents, San Marcos is one of the communities where a single free surf cohort can change dozens of lives per season. Our shuttles and school partnerships make distance (11 miles inland) a logistics problem we solve, not a barrier families carry alone.

Program Curriculum

Ocean Stewardship at Un Mar de Colores connects coastal cleanup action with deeper environmental justice education. Monthly cleanups run across Oceanside, Imperial Beach, Cardiff, and partner sites, with each event combining hands-on debris removal with short teaching moments about the watershed-to-ocean pipeline, the plastic pollution crisis, and California coastal policy. Our Ocean Stewardship program is free and family-friendly, and we specifically prioritize recruitment from BIPOC communities whose relationships with the coast have historically been gated by cost or culture. Every participant contributes to our citizen science database tracking pollution patterns across San Diego County.

  • Beach cleanup fundamentals and safe practices
  • Plastic pollution and marine debris science
  • California coastal commission policy basics
  • Watershed-to-ocean connection
  • Citizen science data collection protocols
  • Advocacy and community organizing skills

Frequently Asked Questions — Ocean Stewardship in San Marcos

How is Un Mar cleanup different from corporate beach days?+

Corporate events are often one-day photo ops without data, policy education, or BIPOC recruitment priority. Un Mar offers monthly continuity, citizen science, environmental justice curriculum, and BIPOC-led stewardship for San Marcos communities.

Are beach cleanups in San Marcos free?+

Yes — 100% free. We provide cleanup supplies (buckets, grabbers, gloves), bilingual safety briefings, citizen science training, and community service documentation. No registration fees or gear purchases for San Marcos families.

Are ocean stewardship in San Marcos really free?+

Yes. All Un Mar de Colores programs in San Marcos are 100% free — including 3/2mm wetsuits, soft-top surfboards, transportation from partner schools like Alvin Dunn Elementary, Paloma Elementary, San Marcos Elementary, and certified bilingual instruction. Funding comes from the San Diego Foundation, community grants, and individual donors. No San Marcos family has ever paid for our programming.

Where exactly do ocean stewardship happen in San Marcos?+

San Marcos is 11 miles inland from the coast, so our cohorts are shuttled to Carlsbad Tamarack (11 miles) — our nearest Un Mar teaching beach. Classroom components including curriculum, cultural arts, and tutoring happen at California State University San Marcos (student volunteers) and partner schools inside San Marcos.

What ages can enroll in San Marcos?+

We serve youth ages All ages. In San Marcos specifically, our recruitment runs through San Marcos Unified School District — with priority enrollment for students from Alvin Dunn Elementary, Paloma Elementary, San Marcos Elementary and 2 other Title I schools. Cohorts are age-appropriate (One Ocean for 6–12, Ocean Stewards for 13–17).

Does my child need to know how to swim before starting?+

No. We begin every cohort with ocean-safety fundamentals in chest-deep whitewater at Carlsbad Tamarack (11 miles), supervised by instructors certified by the San Diego Fire-Rescue Lifeguard Division. Water comfort is built progressively. In San Marcos, we also run pre-cohort pool-familiarization sessions at inland pools via our California State University San Marcos (student volunteers) partnership for students who request extra comfort-building.

Are lessons taught in Spanish in San Marcos?+

Yes. All Un Mar de Colores programs are bilingual — and in San Marcos, where 37% of households are Spanish-speaking, we intentionally pair at least one bilingual coach to every session. Cultural programming is delivered in both languages, and parent communications are always sent in Spanish and English.

How is Un Mar de Colores different from other ocean stewardship in San Marcos?+

Three ways: (1) everything is free, while most San Marcos surf programs charge $50–$150 per lesson; (2) we are BIPOC-led and our coaches reflect the 51%-BIPOC San Marcos 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 San Marcos, not just those who can afford access.

How do I sign my San Marcos child up?+

Visit our sign-up page or contact us directly. Priority enrollment goes to students of Alvin Dunn Elementary, Paloma Elementary, San Marcos Elementary and referrals from California State University San Marcos (student volunteers) and San Marcos Unified School District. Summer cohorts fill 3–4 weeks before start, so early contact is recommended.
