Casti Camp

Casti Camp Castilleja School summer camp

We are looking forward to seeing our campers on campus this summer for fun-filled weeks of activity during Casti Camp 2021. While we may need to adapt certain aspects of our program to ensure the health and wellbeing of our campers and staff, we are planning for in-person camp this summer. Safety will be our highest priority, and joy will be a close second. We are currently developing our policies, including small groups and social distancing, and will update this site with details and FAQs as we learn more. 

Casti Camp is all-day, all-girl fun! Girls who come here experience the true meaning of summer with dedicated time and space for play, creativity, exploration, and discovery. For many new campers, this is their first camp experience, and we immediately see them develop confidence as they settle into making decisions for themselves and building new friendships. For returning campers, we notice they stand a little taller and smile a little wider the moment they arrive.  Casti Camp is a wonderful combination of cherished tradition and exciting activities, creating a world that is both relevant and inspiring for girls today. Our camp is available to rising 2nd-6th graders, and we offer a vibrant Counselor-in-Leadership-Training (CiLT) program to rising 7th-9th graders. These older mentors offer valuable and lasting lessons in leadership to our younger campers.

Casti Camp is located at Castilleja School in Palo Alto, and our facilities include gymnasiums, art rooms, a swimming pool, classrooms, stage, field and more! A delicious lunch and snack is provided every day. Extended Day Care is also available.

Registration will open in January 2021.
NEW: Sibling discount! Get $100 off the two-week session and $200 off the four-week session.

Excellent value! Fantastic counselors, well-organized. I like that my daughter can make choices about the activities she is interested in doing, which is more like overnight camp. I like that she is independent at camp, moving from one activity to another. I also love that food is included and that she loves it!Casti Camp Parent

Girls Rule!

Our campers have a wide range of camp activities from which to choose, and we empower them to select the activities that spark their interest and encourage growth. The choices are wide and varied and are designed by our counselors to inspire creativity, risk-taking, relationship-building, and responsibility. The camp day balances independence, as each camper follows her unique schedule of activities and reflection, with time spent in small counselor-led groups to give a consistent place to start and end each day. Campers also enjoy special activities on Fridays including camper showcases, and all-camp carnivals.


This was our first experience with summer camps in general, and we were thrilled with Castilleja. My daughters are still singing the camp cheers and songs, and we are very excited for next year.Casti Camp Parent
