About Us

Summer at CSB is a co-educational summer program, run by Cathedral School for Boys. We offer unique opportunities for students from preschool through grade 8. Located in the beautiful, historic Nob Hill neighborhood of San Francisco, California, campers will get the opportunity to immerse themselves in engaging and inspiring programming that will keep their minds and bodies active all summer!
Brainworks, our full-day camp, launched in 2014. Brainworks combines classroom education and physical education. Three-hour-long academic classes are held in the morning followed by an afternoon of fun with a sports camp hosted by Cathedral’s own P.E. Department.
City Explorers takes advantage of our incredible location by exploring a new place in San Francisco each day. Campers will learn to navigate public transportation, take in San Francisco’s history, and experience five different neighborhoods each week!
How to Thrive in Middle School is a week-long camp made specifically for students in rising grades 4–6 to help teach and prepare them for what middle school entails.
World Travelers is a camp designed to introduce preschoolers to a classroom setting while exploring different countries and cultures. Each day students learn about a new culture through its foods, customs, traditions, and language.
