I just spent a couple of hours yesterday at Vault Beach, near Mevagissey.  Despite the lovely weather this long and lovely beach had hardly anybody on it and was a lovely place to unwind.  The first part of the beach is for textiles but it soon develops into the naturist area and you can take long walks by the waters edge.  There were even a few nudists braving the water and taking a dip.   Very tranquil and a lovely location for a bit of peace and quiet.
