We passed this tree with a wall in the middle of it, and lunched at a bar and tea-room by the river. Unfortunately the river was too high and fast for the tiny ferry to be running.
Then we had to give up part way through as Finn was not well. One moment he was fine - the next refusing to eat and too quiet for a three-year-old. One minute he wanted to be held upside down, the next he was miserable. Turned out he was developing an ear infection, though it was almost two days before this was clear. He's fine again now.
Since we were with a group we hadn't bothered to bring a map, so our return walk on our own was not the most direct route.
