Summer Camp in London for Teens

The London summer camp where teenagers thrive

Camp St Mary's London, or CSM for short, is a summer camp for teenagers aged 12–17, based on the St Mary's University campus in southwest London.

At CSM, teens from around the world come together for an exciting and immersive summer camp experience, where they can learn English, explore British culture, and, above all, make lifelong friends.

Our all-inclusive summer camp is in one of London's safest boroughs, Richmond upon Thames, set among green open spaces and the historic Strawberry Hill House, just a short walk from the River Thames. Accommodation, classrooms and sports facilities are on site, and city adventures are within easy reach.
