Porthchapel beach, just around the corner from Porthcurno. Not to be confused with Chapel Porth on the other coast. You won't find a cafe, beach-side car park or any facilities here though. In fact you have to be half goat to even get down to the beach here!
However, this isn't the reason it is empty. It's actually a weekday in the middle of winter although it was almost t-shirt weather out of the wind.
