Keros
Keros is the uninhabited jewel of the Small Cyclades, between Amorgos and Koufonisia, a bare 15-square-kilometre island that is one of the most important archaeological sites in the Aegean. It was a major sanctuary of the early Cycladic civilization around 2500 BC, where hundreds of broken Cycladic figurines were deliberately deposited — the mysterious Keros Hoard — and where recent excavations at Dhaskalio revealed a huge proto-urban settlement linked by a causeway to a small islet.
Today Keros is strictly protected and off-limits to visitors, with no anchoring allowed and guards watching the site, which makes its wild beauty even more striking. You can only admire its twin bays and conical hill from a boat passing between Naxos and Amorgos, a stark, sacred island that looks empty but holds the origins of Cycladic art and perhaps the first maritime sanctuary in Europe.
For you if you love sacred history, not sunbeds
Keros is a speck in the Small Cyclades, between Naxos and Amorgos, part of Koufonisia group alongside Schinoussa, Heraklia, Donousa. The trio — Pano Koufonisi, Kato Koufonisi, and uninhabited Keros — forms heart of Minor Cyclades.
It’s not a beach island you stay on. It’s an important archaeological site known for finds from Early Cycladic period 3200-2000 BC, in ancient times called Keria, northwest of Amorgos. White fine-grain marble, white sand and turquoise waters, but no drinkable water, no overnight stays permitted by Archaeological Authority that watches over island. Uninhabited since late 1960s, declared archaeological site under strict protection, opens only with special permission from Ephorate of Antiquities of Cyclades.
Today considered archaeological site, uninhabited except archaeologists who visit for research and few local sheep and goat herders who tend animals from base on Koufonissia. The entire discussion surrounding so-called Keros Hoard shows how important it was — transforming understanding of early Bronze Age Cycladic culture, organizationally technically politically much more advanced than thought. Finds include Treasure of Keros, now in Museum of Cycladic Art and National Archaeological Museum Athens.
If you want to see it anyway
You visit on your own boat or by hiring excursion boat. There aren’t direct ferries to Keros, so you take part in boat trip from nearby Ano Koufonisi — regular boats from town to Kato, and sea taxis to Keros shores for closer look. Boat will anchor near more remote beaches and coves, allowing swim in crystal-clear waters often inaccessible by land.
Tiny Keros currently off-limits to visitors due to ongoing archaeological research, but one to admire as you sail away from Koufonisi towards Donousa. Local sea taxis from Ano Koufonissi and Schinoussa can take you to its shores for closer look at impressive historic gem. Uninhabited island in middle of Cyclades near Koufonisia, only 15 sq m but played vital role in history — flourished 2800-2300 BC.
You reach Koufonisia itself by ferry from Naxos, then day trip. Don’t expect to camp — overnight not permitted.
