Since 1921, Camp Marston has been a San Diego favorite for thousands of children! Adventure, fun, friendships, great staff and a spectacular 236-acre site combine to make memories that last a lifetime. There’s a seasonal pond for fishing and canoeing, oak & pine forests, hiking trails, modern cabins, swimming pool, climbing tower, crafts, play fields and more. Marston is an ideal first step into overnight camping, yet also offers exciting teen-adventure and leadership development programs. The YMCA Mission of positive character development pervades each day. We are proud to be Accredited by the American Camp Association.
