It's such a shame that not everyone takes time to explore a little and critisize a place they have not seen properly.
Triopetra has many beaches and coves along it's coastline that provide for all tastes.
A lovely sandy bay next to it's small harbour backed by a very friendly taverna (where you are always made welcome)...to the 2km stretches of beaches in both easterly and western directions that provide enough space to have a beach to yourselves...and a little more easterly, various coves where you can really be by yourself with nature!
I think it is a truly great place, and thankfully an area that has yet not become to commercialised with just a handful of tavernas, a mini market a few pensions and villas for rent. Highly recommended location.
