Things to Do in Alonnisos: Villages, Beaches & Marine Park
The best things to do in Alonnisos revolve around its wooded landscape, coastal villages and protected seas. Part of the Northern Sporades, the island offers a different setting from the whitewashed landscapes of the Cyclades, with pine-covered slopes, tiled roofs and pebble beaches.
Patitiri is the main arrival point and a practical base for exploring. Above it, the Old Village provides narrow lanes and elevated views, while coastal settlements such as Steni Vala offer opportunities for leisurely meals beside the water.
The surrounding National Marine Park adds another dimension. Visitors can explore permitted areas by boat, learn about marine conservation or arrange a specialist dive to an ancient shipwreck.

1. Explore the Old Village of Alonnisos
The Old Village, also called Chora or Palia Alonnisos, stands on a hill above Patitiri.
Its narrow lanes, stone houses and tiled roofs make it one of the island’s most rewarding places to explore on foot. Restoration has brought new life to the settlement while retaining much of its traditional character.
Allow time to wander rather than following only the main route through the village. Small passages reveal courtyards, churches and views between the buildings.
Late afternoon suits a visit when the heat eases, followed by dinner or a drink. Visitors returning after dark should establish their transport arrangements beforehand.
The lanes include slopes, steps and uneven paving, so comfortable shoes are useful even for a short visit.
2. Spend Time Around Patitiri Harbour
Patitiri is Alonnisos’s main port and an important centre for accommodation, shops and transport.
Although many visitors first encounter it while collecting luggage or meeting a transfer, it deserves time beyond arrival day. A walk around the waterfront provides an introduction to the island’s working harbour and everyday activity.
Cafés and restaurants make it convenient for a relaxed breakfast or meal. It is also a useful place to ask about boat excursions and confirm practical arrangements for exploring elsewhere.
Keep ferry boarding areas and working sections of the harbour clear. Visitors planning a final meal before departure should allow time to collect bags and reach the correct boarding point.
3. Take a Boat Trip Through the National Marine Park
The National Marine Park of Alonnisos and Northern Sporades protects an extensive area of sea, islands and rocky islets.
A boat excursion offers a way to appreciate this landscape beyond the main island. Depending on the operator, route and conditions, trips may include coastal sightseeing, permitted swimming stops and visits to accessible neighbouring islands.
Choose an excursion by its actual itinerary rather than the general description “marine-park cruise.” Some trips cover a limited area, while others involve longer periods at sea.
Ask whether any required park entry charges are included and which stops are planned.
The park is important habitat for Mediterranean monk seals, but sightings should never be expected or guaranteed. The protected landscape is the main reason to visit.
4. Discover the Ancient Peristera Shipwreck
The ancient wreck near Peristera is one of Alonnisos’s most distinctive attractions.
Its cargo of amphorae provides evidence of maritime trade in the ancient Aegean. The site can be visited through organised diving arrangements when operating conditions and permissions allow.
This is a specialist archaeological dive, rather than an activity suitable for every visitor. A participating dive centre should assess certification, recent experience and suitability before accepting a booking.
Divers must follow the guide’s instructions and avoid touching or disturbing archaeological material.
Anyone interested should contact an authorised operator early in the planning process. Availability, equipment requirements and operating dates should be confirmed directly.
5. Visit the Underwater Museum Information Centre
Visitors do not need to dive to learn about the Peristera wreck.
The underwater museum’s information centre occupies the Old School in the Old Village. Its interpretation introduces the shipwreck and the underwater natural and cultural environment.
Interactive and digital material provides an alternative way to understand a site that would otherwise remain inaccessible to many travellers.
This is particularly useful for mixed groups in which only some members dive. It also adds context before a specialist excursion.
Check opening arrangements and the availability of digital experiences before visiting, especially outside the main summer season.
6. Explore the Historical and Folklore Museum
The Historical and Folklore Museum in Patitiri offers a different perspective on Alonnisos.
Also associated with the names Kostas and Angela Mavrikis, the museum brings together material relating to maritime history, traditional occupations and everyday island life.
Its collections help explain the island beyond its beaches, introducing the work, objects and customs that shaped local households.
A visit can fit around time in Patitiri, making it a useful option when taking a break from swimming or waiting for an afternoon activity.
As a privately operated museum, its current opening days and admission arrangements should be checked before travelling specifically to visit.
7. Walk Between the Old Village and Patitiri
The traditional path connecting the Old Village with Patitiri is a rewarding introduction to walking on Alonnisos.
It allows visitors to experience the relationship between the hilltop settlement and the port rather than travelling entirely by road.
The direction matters: walking downhill from the Old Village is less demanding than climbing from Patitiri. However, the descent still requires attention on uneven surfaces.
Use a current route description or map, carry water and wear shoes with a reliable grip.
A practical approach is to arrange transport uphill and walk down during daylight, leaving enough time to enjoy the route without rushing.
8. Explore More of the Island on Foot
Beyond the Old Village connection, Alonnisos has walking routes through woodland, agricultural areas and coastal landscapes.
Options link settlements and beaches, including routes around Isomata, Agios Petros and Steni Vala. Choose a walk according to distance, elevation and current path conditions.
Do not assume that every route is continuously marked or maintained. A recent map or local walking guide is more useful than relying on occasional signs.
In summer, begin early and avoid exposed walking in the hottest hours. Carry sufficient water, a charged phone and an offline map.
For one-way walks, arrange the return journey before setting out.
9. Visit Steni Vala
Steni Vala is a small fishing settlement on the island’s eastern side, north of Patitiri.
Its narrow harbour provides an attractive setting for a slower visit. Walk along the waterfront, watch the boats and allow time for a meal rather than treating it simply as another photograph stop.
The journey also introduces more of the island’s wooded coastal landscape.
Steni Vala can be combined with exploring nearby swimming areas, provided transport and access are checked in advance.
Visitors relying on buses should confirm current services, particularly for an evening return. A daytime visit may be simpler when transport choices are limited.
10. Spend a Day Beside the Sea
Swimming deserves an unhurried place in an Alonnisos itinerary.
The island’s coast includes pebble shores, rocky sections and smaller coves, with access and facilities varying considerably. Some beaches suit a straightforward day by car, while others involve walking or a boat journey.
Choose according to the weather and the facilities required. Visitors travelling with children may prefer easy access and nearby refreshments over a more remote setting.
Water shoes can be useful on pebbles, but they do not replace checking the water entry and conditions.
Avoid attempting several distant beaches in one day. Time spent enjoying one suitable bay is often more rewarding than repeated journeys.
11. Try Alonnisos’s Local Food
Local food offers another way to understand the island.
Alonnisos is particularly associated with tuna, including preserved preparations, while cheese pie is another speciality worth seeking out.
Tavernas also provide opportunities to try cooked vegetable dishes, seafood and familiar Greek meals.
Ask what has been prepared that day and which fish are available. Locally branded tuna products can make practical souvenirs, provided packaging and transport requirements are suitable.
There is no need to make every meal a restaurant search. A few planned visits, balanced with convenient places near the accommodation, leave more time for the island itself.
How Many Days Do You Need in Alonnisos?
Three nights allow time for Patitiri, the Old Village and a beach day or boat excursion.
Four or five nights provide more flexibility for walking, museums and exploring the eastern coast.
Visitors planning a dive or a particular boat trip should allow spare time for weather-related changes. Avoid leaving the most important sea-based activity until the final available day.
Do You Need a Car?
A car makes it easier to explore different beaches and settlements, but it is not essential for every stay.
Visitors based in Patitiri can combine local walking with buses, taxis and boat excursions. Current bus routes and seasonal timetables should be checked against the intended itinerary.
Accommodation in a quieter location requires more planning. Establish how meals, groceries and evening journeys will work before booking.
Exploring Responsibly
The marine park is a protected environment with different access rules across its zones.
Follow current guidance from the park authorities and the excursion operator. Do not approach seals, enter wildlife caves or assume that every island and landing place is open to visitors.
Carry litter away and avoid disturbing plants, animals or archaeological remains. Respecting these limits helps preserve the landscapes that make Alonnisos worth visiting.
