Glaronissi is also part of the Koufonissia island group.
It is uninhabited and lies in the middle of the other three bigger islands.
It is named after the seagulls which have picked it out as a nesting site.
One way to visit it is by the launch.
You will be enchanted by its lovely small beaches and little caves which you can visit by swimming there.
If you arrange such a trip, you should know that you will find yourselves in a virgin place which you can practically have to yourself.
