Hi lisaeugene
That's the same place we used when we went to Laganas beach.. i swam with quite a few turtles last year from here and even in May there was lovely warm currents in the sea.

The beach sweeps right round from Sostis islet to the old fort at Kalamaki although at some points it is used as a road with a drop off and turning point for coaches and delivery lorries along a small length of beach between Laganas main street and Aghios Sostis. And again just by Aghios sostis it is very rocky. A few years back there was a wooden footbridge over all the rocks and this was needed to walk between Laganas and Aghios sostis but the beach has built up at this point and you can now walk along the sand.
Last year there was a heavy storm just days before we arrived in Laganas and the sea was very high and there wasn't much beach at some points with the storm surge in the Ionian sea but, it all got back to normal after a couple of days.
If you want a lovely day out on a beautiful beach you can't go wrong with hiring a motor boat and going out to Marithionnisi island out in the Laganas bay. Sandy beach facing Laganas with a long sand bar coming out from the island and the sea is shallow for some way out here.
And round the back of the island there is a sun trap of a beach with high white cliffs and its got a white pebbly beach very hot around mid day.
