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. Walk-up guests for these tours will be permitted if space is available. However, we strongly suggest contacting us before walking up to a tour. To reserve a place on a tour please call us at 1-709-470-TOUR (8687).
