It’s Kid-Fun Set Free in The Spirit of Nature.. Cali Camp at Big Rock Ranch is a place to roam creek beds, grassy fields and shady oak trees. At Cali Camp campers enjoy over 50 amazing activities supported by a staff that holds hundreds of years of combined experience. And the best part? Transportation is included as an interactive part of the day!! Join us for one of our annual open houses on select Sundays from 10am - 1pm. We believe in the positive impact of camp and cannot wait to meet you and your family soon.
