Two harbours to know before booking Alonissos
Patitiri is where travellers arrive on Alonissos. Steni Vala is the designated departure port for dives on the ancient Peristera wreck. Staying near Patitiri is handy for the ferry and restaurants. A room closer to Steni Vala makes more sense if the dive centre expects you at the harbour early. Confirm the meeting point before reserving a transfer.
Can I dive Peristera on a day trip?
An overnight stay gives you room for the centre’s check dive and the museum slot. Triton usually runs requested wreck trips once or twice a week when conditions allow. Get the proposed dates from the centre before booking a ferry or choosing which night to spend on Alonissos.
What can we see together on land?
The visitor information centre in Patitiri offers a virtual dive among the amphorae. It works especially well for families when only one traveller qualifies for the wreck dive. Leave time for the hillside old village too. Its lanes offer a very different afternoon from the working harbour below.

Some of the oldest stories and myths that are known to man come from ancient Greece. Tales of the Greek Isles entice us with both ancient and modern wonders. From Ancient temples to modern nightclubs, from the top of a mountain where a “god” once sat to seeing a pristine underwater world, Greece awaits to entertain and educate us.

Where to stay?
Patitiri works well for ferry arrivals, restaurants and a visit to the museum information centre. Steni Vala is convenient for the dive harbour. On Santorini or Crete, apply the same test to a hotel you like: how will you reach the centre when the morning boat leaves?
Activities and excursions in Greece
In Athens, pair the Acropolis with the Acropolis Museum to see the sculpture and architecture in context. Around Santorini, Fira and Oia look across the flooded caldera. On Alonissos, a virtual wreck visit and a walk through the old village fit into a day ashore without a ferry connection.
Best time to visit Greece
The peak tourist season runs from late June until early September. August is the busiest month and the prices are highest. Also, July and August see the temperatures soar with many days at 100°F/+40°C.
If water activities are high on your list, the best months may be late May and early June or September and early October. The water temperatures are suitable and the crowds are not at their peak.
Finally, lots of people will agree that, unless you plan on swimming, Spring and Fall are outstanding times to visit Greece!
Health and Safety
On a small island, ask the dive centre how it arranges emergency assistance and onward transport. Eligible EHIC holders can access medically necessary public care under local rules. Separate cover matters for private care and repatriation. European Health Insurance Card guidance
If you are planning an upcoming dive trip or travelling to Greece, it is a really good idea to invest in travel insurance for scuba diving, because you never know what could happen and when you might need it (because accidents do happen!). I recommend this diving insurance as they offer worldwide coverage and focus on providing scuba divers a quality insurance and medical assistance service.
Where is Greece located in the world?
Mainland Greece lies between the Ionian Sea to the west and the Aegean to the east. Alonissos belongs to the Northern Sporades. An itinerary for the Cyclades, including Santorini, uses different ferry connections.
How to get to Greece?
Choose the island before the airport. Alonissos arrivals come through Patitiri harbour, so a ferry timetable matters just as much as the flight schedule. Check the actual connection for your travel date and leave room for a delay before a reserved dive.
Do I need a visa for Greece?
For visitors covered by the Schengen short-stay rule, time spent in other Schengen countries counts towards the same limit of 90 days in any rolling 180-day period. Whether you need a visa depends on your passport and circumstances. Check the official guidance for your nationality before travelling. European Commission visa guidance
Getting Around
Island ferries and local buses solve different parts of the journey. On Alonissos, the ferry leaves you at Patitiri. Ask the centre about the onward ride to Steni Vala, especially for an early departure. For a multi-island trip, check the return sailing as well as the outward one.
Overall, Greece is a dreamy and charming destination. Whether you’re fond of mythology and history, or you’re just looking for a great outdoor adventure and some beach time, Greece has something for you!
