Youth Mentorship Volunteers — San Marcos Adults 18+
Background check paid by Un Mar — not another hidden cost for San Marcos adults who want to serve.
Un Mar de Colores welcomes adult volunteers (18+) from San Marcos to support beach cleanups, youth mentorship, event logistics, and community organizing across San Diego County. San Marcos volunteers regularly support our programming at Carlsbad Tamarack (11 miles) and Oceanside Pier (13 miles) (closest breaks to San Marcos) and partner community sites including California State University San Marcos (student volunteers) and San Marcos Unified School District.

Why San Marcos Matters to Our Mission
Safe, lifeguard-coordinated instruction is non-negotiable for San Marcos youth. Every water session runs inside flagged zones with certified coaches — parents shouldn't have to choose between access and safety.
Whether San Marcos is on the coast or 11 miles inland inland, we treat transportation as part of the program — not an extra parents must figure out. That's how you build real access, not marketing copy.

Frequently Asked Questions — Volunteer Programs in San Marcos
What is cultural competency training?+
Training prepares volunteers to mentor BIPOC youth respectfully — avoiding savior dynamics, honoring cultural context, and supporting trauma-informed environments. Required before direct-youth pairing for San Marcos mentors.
How do I sign up to volunteer from San Marcos?+
Contact Un Mar de Colores or complete our volunteer interest form. Attend free orientation, complete training matched to your role, and background check if mentoring youth. We'll match San Marcos adults to cleanup, event, or mentorship tracks.
Can I volunteer if I don't surf?+
Absolutely — most volunteer roles don't require surfing. Tutoring, cleanup leadership, event logistics, translation, marketing, and organizing are critical. San Marcos adults bring diverse skills beyond board skills.
Are volunteer programs 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 volunteer programs 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 18+. 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 volunteer programs 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.
