Yes, reservations are required for guaranteed spots on all tours. Reservations help us determine the number of pilots and guides we need to ensure that our group remains manageable and enjoyable and they allow us to notify you of changes to the tour due to weather or anything that could interrupt your program. You can always show up and enroll too but you may have to wait for your turn as we conduct our flights on first come first serve basis for walk in clients and you may not get a slot on the particular day.
