Like David, we've stayed at Gandspette lots of time. Hard to count, but almost every time we're going home from France, twice a year, for at least the last thirteen years!! I like it there. We've always been 'recognised' and our previous stays acknowledged - much to say, Aah - here again - just the one night??!!!! The facilities have been upgraded, the new area is lovely, and the new block is of a high standard, the pitches in the new area are large (if not quite level). The restaurant is cheap, and the food good, for what you pay. You can get to the ferry in 30 - 40 minutes, on an easy route, and we've never found anywhere better to stay near to the ferry port. Best of all, when we go, using Camping Cheques it is very inexpensive. One year we stayed two nights, to explore the area, and found it much more interesting then we'd thought.
I can imagine, on a cold, rainy, dark, September night, when the site is almost empty, the trees might make it a little foreboding, but that would apply to almost any site in France under those conditions.
