A Greece itinerary works best when it balances two countries in one, the mainland of ancient sanctuaries and mountain monasteries, and the islands of caldera sunsets.
Encounters Travel runs the mainland loop as the Classic Greece tour, a guided week through Athens, the Peloponnese, Olympia, Delphi and Meteora.
This guide joins both halves without rushing, then hands the final days to the Aegean with a short flight to Santorini.
You will see how many days each region genuinely needs, what to skip, and how the pieces fit into ten days.

How many days do you need in Greece?
Seven days is the honest minimum for Athens plus the mainland loop.
That week covers Mycenae, Olympia, Delphi and Meteora without padding, but it leaves no room for the islands.
Ten days is the sweet spot for a first visit.
You keep the full mainland circuit and still get three or four nights on an island, which is what most people picture when they dream of Greece.
Two weeks opens up the wider Cyclades, Crete or the northwest.
Beyond that, you are adding places rather than improving the trip.
One warning about short visits.
Day trips that promise Athens in a day from cruise ports leave no room for the museum, the old town or any meal that involves sitting down.

Athens deserves more than a layover
Give the capital three nights.
Many routes treat Athens as an airport with ruins attached, and that is a mistake, because the city rewards slow evenings as much as sightseeing.
Start high.
The Acropolis holds the Parthenon above the modern city, and morning visits beat both heat and crowds.
Below it, the Acropolis Museum puts carvings and sculptures in context.
Seeing the originals up close changes how the hilltop monuments read afterwards.
Save the afternoon for the old town.
Plaka tumbles down the hillside in narrow lanes, while nearby Monastiraki mixes flea markets, kebab stalls and rooftop bars under the Acropolis.
Evenings belong to a taverna.
Order simply and eat slowly, because in Athens dinner is a social event that starts late.
The city also layers newer history, from the Panathenaic Stadium to the Temple of Olympian Zeus, Hadrian's Arch and the neoclassical trilogy of Academy, University and Library.
Into the Peloponnese: Mycenae, Nafplio and a canal
Leave Athens by road and the mainland opens up.
The first stop is engineering rather than antiquity, the Corinth Canal, a narrow slot cut through rock in the 19th century.
An hour on, Mycenae appears.
This was Homer's rich in gold, the Bronze Age citadel of Agamemnon, entered still through the Lion Gate beneath walls the ancients believed giants built.
Nafplio makes the natural pause.
This seaside town of Venetian balconies and sheltered harbour suits lunch and a slow wander, while the Palamidi fortress above rewards the climb with views across the Argolic Gulf.
The same region holds Epidaurus.
Its ancient theatre is famed for acoustics so precise that a whisper on stage carries to the top row.

Olympia and Delphi: sanctuaries that shaped the ancient world
West into the hills lies Olympia, where the Games began in 776 BC as a festival for Zeus.
You can still stand on the original stadium's grass starting line.
The museum holds the Hermes of Praxiteles, one of the great sculptures of the ancient world.
Together site and museum explain why athletes travelled here from every corner of the Greek world.
Delphi feels different.
High on Mount Parnassus, this was Apollo's sanctuary, where rulers consulted the oracle before going to war.
The Greeks called it the navel of the world.
Today hillside ruins and the bronze Charioteer make it, for many travellers, the highlight of the mainland.
Meteora: monasteries balanced on rock
The mainland saves its strangest landscape for last.
At Meteora, active monasteries perch atop stone towers that rise hundreds of metres from the valley floor.
Monks first reached these summits by rope and basket.
Six communities remain, and several welcome visitors, provided shoulders and knees are covered.
Visiting brings quieter roads, cooler mountain air and views that explain why the first hermits stayed.
From here the route runs south toward Athens, often pausing at Thermopylae, where a monument marks the Spartan stand.

Island time: why Santorini closes the trip well
After a week of ruins and road, an island resets the rhythm.
Santorini is the classic choice, and its geography alone justifies the reputation, the rim of a drowned volcano.
Villages such as Fira, Imerovigli and Oia line the caldera edge, whitewashed above one of the Mediterranean's great views.
An Oia sunset has become a nightly event, and crowds are real.
The remedy is simple, arrive early, find a wall to lean on, and watch the caldera change colour.
Below the rim, beaches run black and red rather than gold.
Vineyards produce distinctive white wines, and a tasting makes an easy afternoon, while boat trips sail to the steaming crater and pause for a swim in warm springs.
Prefer sand and swimming?
Mykonos is the other headline Cyclades island, known for beaches, windmills and Little Venice alleys, and ferries link the two.
For a quieter close, Naxos and Paros offer a slower pace, while Crete and Milos suit longer trips.
The same mainland loop runs guided as our Classic Greece tour, with island nights easy to add at the end for a ten day shape.
One week in Greece? Keep it simple
If you cannot stretch past a week, cut the road loop rather than the island.
Athens plus Santorini, roughly three nights each plus travel, still delivers ancient history and a caldera sunset.
Avoid adding a second or third island.
Every ferry crossing costs half a day of checking in and out, and two bases beat three on a short trip.
Ferries, flights and getting around
Flying from Athens to Santorini takes about 45 minutes.
Fast ferries take around five hours, but arrival through the caldera is a spectacle in itself.
On the mainland, distances deceive.
Roads are good, but mountain routes between Olympia, Delphi and Meteora eat hours, which is why the loop works best with a driver or guide who knows them.
Athens airport connects by metro, rail and taxi, and most central hotels sit within a short walk of a metro stop, so a car is unnecessary in the capital.
Book peak season ferries and island stays early.
August crossings fill fast, and caldera view rooms go months ahead.
When is the best time to visit Greece?
May, June, September and October are ideal.
The sea is warm, sites are open, and light is kind to photographers.
July and August bring intense heat and the biggest crowds.
Winter is quiet and atmospheric on the mainland, though island schedules shrink.
Plan smart: Greece essentials for first-timers
A few practical points turn this outline into a booking.
- Keep budget for entrance fees at major sites, which vary by season and are settled as you go.
- Expect a small hotel residence tax, paid directly to your accommodation.
- Arrange travel insurance covering medical care before you travel.
- Pack for churches and monasteries as well as beaches, with covered shoulders and knees.
- Stay near Plaka or Monastiraki to keep Athens evenings car free.
- Check your passport validity and current Schengen entry rules before booking.

What stays with you after ten days in Greece
Greece rewards travellers who give each half its due.
Spend days among sanctuaries, fortresses and monasteries, with a taverna table waiting each evening.
Then let the Aegean do what it does best, turning gold, then pink, then dark blue above the caldera.
Everything you need to know before you go
How many days do you need for a Greece itinerary?
Seven days covers Athens and the mainland loop of Mycenae, Olympia, Delphi and Meteora. Ten days lets you add Santorini without rushing either half.
Is 10 days in Greece enough for Athens and an island?
Yes. Three nights in Athens, three on the mainland loop and three or four on an island is a balanced shape that avoids constant packing.
Should I choose Santorini or Mykonos?
Santorini suits caldera views and the Oia sunset, while Mykonos suits beaches and nightlife. Ferries connect the two, so some visitors see both.
Is it better to fly or take the ferry from Athens to Santorini?
Flying takes about 45 minutes, fast ferries take around five hours. In peak season, book either well ahead.
Do I need a visa for Greece?
Greece is in Schengen, and many nationalities, including UK, US, Canadian and Australian holders, enter visa-free for short stays. Check current rules before booking.
When is the best time to follow this Greece itinerary?
May, June, September and October offer warmth with fewer crowds than peak. July and August are hottest and busiest, winter quiets the islands.
