Alonnisos — Patitiri

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.

Getting there

⛵ via Skopelos€20–35

No airport. The most remote Sporades island — reach from Volos/Agios Konstantinos via Skopelos. Marine park around the island protects monk seals.

Tip: Combine with Skopelos for a quieter Sporades trip — Skiathos can be skipped.

When to Visit

Alonnisos sits inside Greece's biggest marine park (Mediterranean monk seal habitat) — boat trips to the protected islands of Kyra Panagia and Peristera are the main attraction. Quieter than Skiathos and Skopelos. Best May-October. June and September. This is a hiking and snorkelling island.

Jun
Sea warming, the marine park boat tours starting (seal-spotting at its best in low season), the Old Chora hill paths walkable. The realistic best month for the island.
Jul
Hot, peak Sporades summer, Patitiri harbour busy. The interior pine paths and the small fishing coves (Megalos Mourtias, Tzortzi Gialos) stay quiet.
Aug
Peak — small island fills up, marine park boats fully booked, prices at maximum. Alonnisos is small (64 km²); August feels more like Skiathos than the quiet island the rest of the year. The marine park itself stays uncrowded — that's why it exists.
Sep
Charter season winding down, the seal-spotting boats returning to small groups, the maquis trails (Old Chora to Megalos Mourtias) walkable in golden afternoon light.

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
    Full-day boat trip into the National Marine Park — the largest protected marine area in Europe and home to the Mediterranean monk seal. Book from the harbour the day before.
  2. 11:00 · Gioura Island
    Wild uninhabited island in the marine park. The cave here is claimed to be the cave of the Cyclops Polyphemus from the Odyssey. Extraordinary wildlife — wild goats, rare birds.
  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.
  4. 16:00 · Monk Seal Spotting
    The waters around Alonnisos have the highest concentration of Mediterranean monk seals in the world — about 40 individuals. Patient boat skippers often spot them in the late afternoon.
  5. 17:30 · Return to Patitiri
    Boat returns to Patitiri Port in late afternoon (about 90 min from the marine park area). The harbour fills up at dinner time — Patitiri's fish tavernas are some of the best in the Sporades.

Day 3: North Beaches & Departure

Drive: 25 km, ~35 min

  1. 10:00 · Agios Dimitrios Beach
    Remote sandy beach on the north coast — accessible by a rough road or by boat. White sand, crystal water, almost always empty. One of the finest beaches in the Sporades.
  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.
  3. 16:30 · Patitiri — Departure
    Ferry to Skopelos, Skiathos, Volos or Thessaloniki. Alonnisos is the end of the Sporades line — ferries are less frequent than on the other islands, check timetables.
