I have been there few years back. It is a lovely bay with small sandy central part and rocks on the side. Camping is pretty much basic, not many facilities. There is a diving school. You need to have a car to go there and they charge for the entrance if you want to visit the beach for a day.
Yes, it is a sort of a "primitive" camping, a good place for those seeking almost untouched nature. Some plots have electricity and water connections, there are two or three sanitary units, small kiosk and fast food and that's it. Also, it is clothing optional place, because most of campers stay nude around their tents and nobody cares... The main sandy beach is textile.
