I went to a place called Amoudi in Zante / Zakynthos for my honeymoon in 1996.
Many visitors thought it was too remote, I thought it was great. However, they were intending to build there, and I guess it may now have been commercialised.
The sea there also takes forever to get deep, a lovely slow walk into it.
Alykes and Alykanas are nearby also.
It was idyllic at the time (Amoudi).
