Just returned from camping in France - the cheap option. Stayed at Camping des 2 Rivieres, Martigny, a few miles south of Dieppe - beautiful site situated, as the name suggests, between two rivers and by a series of lakes - former gravel pits? Fortunately, we only found out on departure that the annoying mechanical noise carried by the wind on certain nights emanated from the busy local abattoir.
Recommended: the excellent salt water swimming pool by the beach at Dieppe - heated outdoor pool and indoor pools and baths; Cafe des Tribunaux in Dieppe, haunt of Wilde and various Decadents; Le Chapeau Rouge restaurant, Neufchatel-en-Bray.
Not recommended: Le Galion restaurant, Quai Henri IV Dieppe - overpriced and undercooked.
