Porto Katsiki is the most famous beach of Lefkada, like Navaggio is for Zakynthos. It is a narrow strip of sand located below high white cliffs and the water has a sparkling milky blue color (if this color exists at all, the water of Porto Katsiki fully depicts it).
The beach is on the southwest tip of the island, away from towns and villages but accessible by car. The closest populated area is the village of Athani, 12 km away. The resort of Vasiliki is at a distance of 30 km. The road from Athani to Porto Katsiki is narrow, with many curves and at some place it hardly fits two cars side by side. The traffic is terrible in July and August and you may expect difficulties finding a place to park. There is a parking lot above the beach but its capacity is not enough during the high season so most cars park directly on the narrow road. Next to the parking lot there are some canteens with view of the beach from above. To get to the beach, there are a few stairs going down.
The beach is shingle, mixed with sand. Until noon it is shaded by the cliffs behind it but in the afternoon you will need sun umbrella - your own or rented.
If you do not have a car, you can visit the beach with some of the organized boat trips.
