Athens and Santorini in 7 Days: Complete Itinerary (+ Mykonos) 2026

A week in Greece is the perfect length to combine the antiquity of Athens and the magic of the Cyclades: 2 days in Athens for the Acropolis and historic districts, 3 days in Santorini for the caldera and its sunsets, then 2 days in Mykonos for its windmills, beaches and nightlife. Here is the day-by-day itinerary, flight and ferry connections, 2026 prices, the total budget and the best season. Each stop can then become your personalized itinerary in 30 seconds with NavorAI.

Greece in 7 days: the plan at a glance

Days 1-2: Athens, the Acropolis, its museum, Plaka and Monastiraki. Days 3-5: Santorini, Oia, Fira, the caldera, Akrotiri and the volcanic beaches. Days 6-7: Mykonos, Little Venice, the windmills and the beaches. The easiest route: a flight from Athens to Santorini, a fast ferry from Santorini to Mykonos, then a flight or ferry from Mykonos back to Athens.

Days 1-2: Athens and the Acropolis

Start with the Acropolis at 8am opening time, with a slot booked online: the ticket costs €30 in 2026, and the hill is far more pleasant before the heat and the groups. Then walk down to the Acropolis Museum (about €20), whose glass walls face the Parthenon. In the evening, dine in the lanes of Plaka. On day two, visit the Ancient Agora and the Temple of Olympian Zeus, wander around Monastiraki and end at sunset on Lycabettus or Philopappos Hill, with the Acropolis lit up.

Days 3-5: Santorini, the caldera and its sunsets

Fly to Santorini, about 45-50 minutes from Athens. Stay in Fira, Firostefani or Imerovigli for caldera views, or in Oia for the world's most famous sunsets. Day 3: the cliffside hike from Fira to Oia, about 3 hours with spectacular views. Day 4: the Akrotiri site (about €12), a Bronze Age city buried by the eruption, then Red Beach and dinner in Pyrgos. Day 5: a caldera cruise with a swim in the hot springs, or an Assyrtiko white wine tasting at an estate.

Days 6-7: Mykonos, windmills and beaches

Take the fast ferry from Santorini to Mykonos, about a 2.5-hour crossing, to book ahead in summer. On the first day, get lost in the white lanes of Chora, admire the windmills and Little Venice at sunset, then dine by the water. On the second day, choose your beach: Psarou and Platis Gialos to relax, Paradise and Super Paradise for a party vibe, or Agios Sostis, wilder. Return to Athens by a 40-minute flight or by ferry.

How much does 7 days in Greece cost?

Indicative prices per person in 2026, in shoulder season. • Visits: about €70 (Acropolis €30, Acropolis Museum €20, Akrotiri €12, Ancient Agora). • Transport: Athens-Santorini flight, Santorini-Mykonos ferry and return to Athens, about €180-320 depending on when you book. • Meals: €35-60 per day in tavernas, so €245-420 for the week. • Caldera cruise: about €60-120. • Total excluding accommodation: about €560-930 per person. • Accommodation: allow €100-180 per night in Athens, €180-400 in Santorini with a caldera view, and €150-300 in Mykonos. For two people, a comfortable week comes to around €2,300-4,000 all in, excluding international flights.

Where to stay in Athens, Santorini and Mykonos?

In Athens, Plaka and Koukaki are perfect for doing everything on foot, at the foot of the Acropolis. In Santorini, Imerovigli and Firostefani offer the best caldera views, with more calm than Oia; Kamari and Perissa, on the beach side, are more affordable. In Mykonos, stay in Chora for the evening atmosphere, or near Ornos and Platis Gialos for the beach.

What to eat in Greece?

Moussaka, souvlaki and gyros, Greek salad with feta, tzatziki and grilled octopus are must-tries. In Santorini, taste fava, a yellow split pea purée, and the local cherry tomatoes, with an Assyrtiko white wine. In Mykonos, kopanisti, a spicy cheese, and the small fishermen's tavernas. Everywhere, finish with Greek yogurt and honey.

Our tips for a great week in Greece

Book the Acropolis, flights and ferries as soon as your dates are set: in July and August, everything fills up fast and prices climb. Allow some slack for ferries, sometimes delayed by the meltemi, the Cyclades' summer wind. Visit sites early in the morning to avoid the heat. And do not try to see too many islands: two islands in a week is the right pace.
