Making a world of difference since 1916


Welcome to the Caltech Y's website! The Caltech Y provides students with unique and valuable opportunities to explore their interests and grow into responsible citizens of the world. With the Caltech Y, students have gone on cultural trips to South America and India, hiked and camped through weekend trips, volunteered at local schools, and listened to ambassadors talk about science policy. We hope you can use this site to learn more about everything the Caltech Y does, and find something that interests you.
