Zakynthos has the shape of an arrowhead, with the "tip" (Cape Skinari) pointing northwest. The western half of the island is a mountainous plateau and the southwest coast consists mostly of steep cliffs. The eastern half is a densely populated fertile plain with long sandy beaches, interrupted with several isolated hills, notably Bochali which overlooks the city and the peninsula of Vasilikos in the northeast. The peninsulas of Vassilikos to the north and Marathia to the south enclose the wide and shallow bay of Laganas on the southeast part of the island.
