Online Cancellation Request
To help expedite cancellation requests, we are currently accepting online cancellation requests for bookings that fall outside of our cancellation booking windows. If your arrival or start date is within the cancellation booking window, please contact 800.MAMMOTH. If you booked through a 3rd party booking agency, please contact them directly to process any cancellation requests.
By submitting the Cancellation Request Form below, you authorize Mammoth Mountain to cancel your lodging or activity reservation and agree to the cancellation policy that applies to your specific reservation (to view our current policies, please see the links at the bottom of this page).
Once you submit your cancellation, you will receive a confirmation email within 72 hours. The cancellation confirmation email will include further details on the policy applied to your reservation. During high-demand periods, this process can take up to 7 days.
Please note — if we cannot confirm your information, your online cancellation request will not be accepted and you will receive a follow-up email to contact us.
