Sights in Zakynthos
Two are the main attractions of Zakynthos: the turtles Caretta caretta and the shipwreck Navagio. The National Marine park of the island includes the beaches in the bay of Laganas and one of the most popular boat cruises is the trip to "turtle island" - the small Marathonissi. During this trip you may see turtles and swim with them (not always), and nests with eggs can be seen on some of the beaches.
Also, do not miss the chance to take the trip to Keri Caves and the Blue Caves, enjoy the view from Bohali and the castle and spare an evening to watch the sunset from Kampi and Agalas.
