Greece Travel Guide 2026: Islands, Itineraries & Essential Tips

When is the best time to visit Greece?

The best time to visit Greece is during the shoulder seasons of May, June, September, and October. You will experience pleasant beach weather (20–28 °C) without the extreme heat, peak prices, and large crowds of July and August.

How many days do you need in Greece?

You need at least 7 to 10 days for a first-time trip to Greece. That gives you 2 days for the historical sites in Athens plus 5 to 8 days island-hopping between two islands such as Santorini and Naxos, or Santorini and Crete.

Do I need a visa to visit Greece?

Visa requirements depend on nationality and trip length. Many visa-exempt non-EU visitors can use the Schengen short-stay rules for up to 90 days in any 180-day period. For non-EU nationals using the Schengen short-stay rules, the passport must be valid for at least 3 months after the intended EU departure date and have been issued within the previous 10 years. ETIAS is not operational. It is planned for the last quarter of 2026, but the exact start date has not been announced. The application fee will be €20.

How much does a trip to Greece cost?

A budget traveler should plan for €60–€80 per day. Mid-range travelers should budget €150–€250 per day including hotels, ferries, and dining. Popular islands like Santorini and Mykonos run 30–50% higher than the mainland or quieter Cyclades islands.

What new 2026 fees should I budget for?

From April through October, Greece's climate-crisis resilience fee per room and night is €2 for 1–2-star hotels, €5 for 3-star hotels, €10 for 4-star hotels, and €15 for 5-star hotels; lower rates apply from November through March. Cruise visitors to Santorini should confirm the applicable disembarkation fee with their cruise operator before travel.

How do I get between the Greek islands?

Ferries are the most common option, with high-speed routes connecting Santorini, Mykonos, and Naxos in under two hours. Domestic flights from Athens cover Crete, Santorini, Mykonos, and Rhodes in roughly 45 minutes. Book peak-season ferries 2–3 months ahead.

Meltemi winds can trigger Coast Guard sailing bans in July and August — keep a domestic-flight backup for time-sensitive connections.

How are heat waves affecting sightseeing in Greece?

The culture ministry closes the Acropolis and other open-air sites during 40 °C+ surges, and the same protocol applies for 2026. Book the earliest entry slot, carry water, and plan indoor activities (museums, food tours) between noon and 5 p.m.

When should I book accommodations and tours?

Reserve peak-season stays 3–4 months ahead (longer for Santorini caldera hotels) and lock in ferries and tours at least 3 weeks in advance. Shoulder-season trips can usually be booked 4–6 weeks out with free-cancellation rates.
