Dates are available throughout the year for all ages and this site is updated as new camps become available.

Camp COSI Cancellation Policy:
Single-Day Camps
If you can’t attend your single-day camp, contact COSI at least 24 hours before your program. COSI will attempt to reschedule you into an open session. Refunds are not available. COSI can only reschedule a missed workshop once.

Five-Day Camps

Cancellations and changes must be made at least 10 days before the first day of any weeklong camp; a $40 cancellation fee applies. Refunds cannot be issued for cancellations made later than 10 days before the first day of a weeklong camp. COSI may cancel sessions if participant minimums are not met. Registered participants will be informed two weeks in advance and will receive a full refund.

Please note that selected COSI program reservations are subject to a nominal processing fee. Proceeds from this fee help to support COSI, a not-for-profit organization. For selected programs, transaction fees may be waived for COSI Members as a benefit of membership.
