We have been to Lady's Mile Dawlish Warren and bay view farmers campsite near Woolacombe too. Lady's Mile was quite noisy on the bottom field near the pool etc but the top field where we stayed was quieter. We saw lots of rabbits at the nature reserve : ) Bay view farmers is a nice quiet site, with a dog walking field and direct access to the tarka trail and you can see the sea from a distance. Both are a little way away from the beach/ sea though
