Nice places that are not far away

The past couple of weeks we had the opportunity to go on excursions in places not far from Athens. Which, reminded us that some times you don't have to travel far to find places of interest.
Here they are then:
The Acrocorinth, the Isthmus of Corinth, the lake of Vouliagmeni and the Heraion. (including a photo with the beautiful lighthouse near Heraion).
