In the fourth instalment of the series we’re headed to Keros, and island that only archaeologists are normally allowed to visit. From there it’s off to Schinoussa, where amongst other things, Peter will be exploring the food culture that sets it apart from neighbouring islands. After that, Mia Zoi is headed a couple kilometers westward to the wild and remote Iraklia, which might be the largest of the lesser Cyclades, but is one of the least developed.
