Partnering with the National Park Service at Point Loma, San Diego's Cabrillo National Monument since 1956, Cabrillo National Monument Foundation is the 501(c)(3) that funds the youth education, conservation, and visitor-experience programs that federal entrance fees alone cannot sustain at San Diego's only National Park. The Foundation underwrites field programs including the Science Explorer Club, Conservation + Comics curriculum, Open Outdoors for Kids days, and the Snake Ambassadors interpretive series, filling gaps in the same public-lands education continuum managed by the CA State Parks-San Diego Coast District Office at the state level. The on-site Cabrillo Store inside the Visitor Center sells books, gifts, and commemorative items whose proceeds flow directly back into park programming — a cooperating-association retail model authorized under NPS Director's Order 32. Annual membership tiers provide household benefits and early access to special events, while the Legacy Society recognizes donors who commit estate gifts through wills, trusts, or retirement accounts to secure the Foundation's endowment. The Monument's 160-acre coastal bluff shares the peninsula with Fort Rosecrans National Cemetery, and the Foundation's trail-construction and tidepool-monitoring initiatives protect habitat along the same headland where the Old Point Loma Lighthouse has stood since 1855. The most resource-intensive project in the Foundation's current portfolio is the multi-phase trail expansion connecting Sunset Cliffs viewpoints to the monument's interpretive core, a capital campaign that blends donor funding with NPS engineering oversight.
