Cancellation and Refund Policy

Cancellations made up to 15 days prior to the program start date will be refunded, minus a $4.95 Active registration fee. Cancellations made 14 days or fewer before the program start date will not be refunded. No refunds can be issued for no-shows once a program has started. If MOSS cancels a program due to not meeting minimum enrollment or other unavoidable situations, refunds will be made. Many of our camps have waitlists so last-minute cancellations keep other kids from enjoying the outdoor experience. Thank you for your understanding.

Despite our best efforts, the public health situation may change throughout the summer. If MOSS is unable to adequately provide for health and safety during the summer, we will cancel camps and communicate closures with as much notice as possible. We ask for your understanding if COVID-19 health concerns require us to cancel camps.

Be Prepared

Your camper will have the best experience if they're prepared for everything the day brings. Our gear list can be found here. Feel free to contact us with any questions about necessary gear.

Program Expectations

On the first day of MOSS camp, instructors lead students in understanding expectations for safety and respect. If a student's behavior presents a concern for their safety or the safety and enjoyment of others, they may be removed from all or part of camp. In such cases, no refunds are issued and the student may be precluded from participating in future MOSS programs.
