Yes. Reservations are required for guaranteed spots on all tours. Reservations help us determine the number of guides we need to ensure that our groups remain manageable and enjoyable, and they allow us to notify you of changes to the tour due to weather or anything that could disturb the tours.
You must call 72 hours ahead of your scheduled tour for a full refund. Within 72 hours you will assess a $35 termination fee. There are no refunds for cancellations within 24 hours of your tour, or if you decide not to show up.
