It's adjacent to the beach - just take the path through the dunes. The sea shore is not officially naturist, but it's so remote nobody bothers.
We are regular visitors (members) to Lakeland Club with our Hymer S700 and Trailer. You need transport to get water from the farm if you stay a while as it is 2km away. It is one of our regular spots. Day visits £5 per adult http://www.loc.ic24.net/
