Koukounaries

You'll find this well-stocked supermarket right at the start of Koukounaries road near bus stop 3, operating under the name Skiavenitis. The store features reasonable prices and includes a coffee shop inside, making it a solid spot to grab groceries and take a break. The friendly staff and good selection make it one of only two supermarkets in the area, though you'll need to factor in the walk if you're staying further down the beach with heavy items like water bottles.
