When we stayed with Christian and Edith in June, one of the reasons for doing so was to visit the artist Claude Monet's famous garden at Giverny. Christian and Edith live about 15 minutes away from Giverny, but have never visited the garden - quite enough nature on their doorstep to keep them occupied I think, and they both prefer wilder places.
Monet's garden is probably on most visitors to France's 'must-see' list. It was on mine, and up till June, I had not seen it. Now that I have, I can report that it is indeed a very beautiful garden, jam packed full of very prettily arranged plants, and slightly less appealing numbers of other visitors, including some very pushy photographers who hog the best vantage points. It is not somewhere I will feel the need to visit again, although I am pleased to have seen it now. (The reason relatively few people appear in the photographs I took is that the paths are all extremely narrow, and many of them are roped off, so one can aim the camera up the length of the garden and not capture a single person on the path because there is no access it -- you can look, but not perambulate.)
