Cancellations and Refunds


Many of our programs fill quickly and have waitlists. If you need to cancel your registration, please call 410-535-5327 or email

Weather Policy. Most programs are held rain or shine. For winter weather, if Calvert County schools or government are closed, programs are canceled. If there is a delayed opening, morning programs are canceled. We try to post cancellations as timely as possible.

For Programs at Flag Ponds Nature Park: Program participants do not need to pay the entrance fee on the day of the program. The entrance fee will be required on any other visit to the park.


Calvert Nature Society will refund payments made for program fees over $10.00 when the cancellation occurs a month before the event. A $5 administrative fee will be charged. Program fees under $10 will not be refunded.

If the Society or Calvert County cancels the program, a full refund will be given.

Refunds are available only for transactions involving the purchase of goods and services. Dues payments are not refundable.
