Featured by UNESCO as a place of exceptional natural beauty, this small blue lagoon is 16 kilometers from Loutraki, and is very close to the archaeological site of Heraion, from where it was named (Heraion Lagoon) and its settlement Peira. The entire lakeside road (about 5km) is ideal for cycling.
Its depth does not exceed 40 meters, its length is 2 kilometers and its width is 1 kilometer. Its beach is sandy and with a narrow channel its waters communicate with those of the Corinthian Gulf.
Its waters, much more salty than the high seas, renewed by the tide and low tide every six hours, are at first shallow and later deepening. They are considered particularly warm and allow swimming until late in the autumn.
It is an ideal family destination and offers the visitor the opportunity to enjoy water sports, visit the picturesque chapel of Agios Nikolaos or the water-releasing canal to the Corinthian Gulf and enjoy good food, drink or coffee with a backdrop of paradise .
In recent years, the location has been the meeting point of many sport events as well as social events, such as weddings and christenings, with the aura of the sea.
