For all single day trips, AVA offers a 90% refund to any guest who needs to cancel their adventure until 7:00 PM MT the night before the trip date. Trip changes after 7:00 PM will result in a 15% change fee and are subject to availability. If you do cancel your reservation after 7:00 PM the night before the trip, your reservation will be converted to an open credit equal 85% of the total cost of your adventure. The credit is valid for the current season only. AVA reserves the right to cancel any trip due to an insufficient number of bookings. Should we need to cancel your trip, the full cost will be refunded or credited to another trip according to your wishes.
