We may cancel tours due to extreme weather conditions or unforeseen events. Most of our tours also require at least three participants to run. We will do our best to determine any cancellations as soon as possible and immediately inform customers via email of any changes to the event. Should any of our tours be canceled for these reasons, we will offer you a full refund, an option to reschedule on a different date or pay for the remaining slots needed to reach the minimum number of participants.
