There are many options for balloon rides that do their best to take you over the famous chateaus of the Loire valley. Since they are so dependent on wind direction, nothing is guaranteed, but they do their best to give you some good views, and in any case, it's good fun. We have done one.
We spotted this balloon coming towards us from across the river, looking like it was aiming at the Chateau at Saumur. So we paused on our way to the evening restaurant, waiting to get a good picture of it above the bridge. It came down in a field on the other side of the river before it got to us. Shame.
