Alonnisos

The old village, the marine park boat trip, and the deserted beaches of the north coast.

Overall rating: 3.8/5 · 64 km² · 2750 residents

Alonnisos is the least-developed major island in the Aegean — mostly car-free lanes, dense maquis, and a marine park protecting the last monk seal population in Europe. The island was devastated by a 1965 earthquake and the population mostly moved away, leaving the old hilltop village abandoned. Today it's the most peaceful and wild island in the Sporades, with beaches accessible only by boat and water of extraordinary clarity.

3-day itinerary for Alonnisos

Day 1: Patitiri & the Old Village

Overnight: Patitiri · Drive: 10 km, ~15 min

  1. 09:00 · Patitiri
    The main port — a small, relaxed harbour town with good tavernas and a helpful boat-trip booking office. Pick up a rental scooter or car here.
  2. 10:00 · Chora (Old Village)
    The abandoned hilltop village slowly being restored by hippies and artists who moved here in the 1970s. Extraordinary views, medieval lanes, and a completely different atmosphere to the port.
  3. 12:00 · History & Folklore Museum
    Small museum in Patitiri covering the island's fishing and seafaring heritage. The exhibits on the monk seal and marine park are worth seeing before the boat trip.
  4. 15:00 · Roussoum Beach
    Pebble beach just south of Patitiri — calm, clear water, easy access. Good for a first-day swim while you find your feet.

Day 2: Marine Park Boat Trip

Overnight: Patitiri · Drive: 5 km, ~10 min

  1. 09:30 · Patitiri — Boat Departure

  3. 14:00 · Peristera Island
    Uninhabited island opposite Alonnisos with deserted sandy beaches and crystal water. Most boat tours stop here for swimming and snorkelling.

Day 3: North Beaches & Departure

Overnight: · Drive: 25 km, ~35 min

  1. 10:00 · Agios Dimitrios Beach

  2. 12:30 · Leftos Gialos Beach
    Sandy beach midway up the west coast — calmer than the north coast beaches and slightly easier to reach. Good swimming and a small taverna.
