Agios Efstratios: The Silent Sanctuary of the Northern Aegean
Agios Efstratios (Ai Stratis) is one of the most remote and peaceful islands in Greece. Located in the heart of the northern Aegean, it is a place of vast silence, rugged volcanic beauty, and a small, resilient community. In 2026, Ai Stratis is the ultimate destination for the ‘off-the-grid’ traveler—someone who wants to experience Greece as it was before the arrival of tourism. It is an island of deserted beaches, rich fishing grounds, and a commitment to becoming a 100% green-energy island.
Things to know about Agios Efstratios
Geographically, Agios Efstratios is a small, triangular volcanic island between Lemnos and Skyros. Historically, it was a place of exile for political prisoners for much of the 20th century, which has left a mark of quiet dignity on the island. An ideal trip length is 2-3 days for total relaxation. It is famous for its sea caves (home to the Monachus-Monachus seal), its exceptional lobsters, and its status as a Natura 2000 protected site.
