Camp Trinity on the Bar 717 Ranch is the oldest accredited co-educational summer camp in California. Since 1930, the Gates family has welcomed boys and girls ages 8 to 16 to live, work, and play on 450 acres of pristine wilderness as part our large ranch family. Today, the pioneer traditions of cooperation, resourcefulness, and respect for the land are the foundation for wholesome summers filled with fun and friendship, rewarding new experiences, and a deep connection with nature.
