Introduction

Norwegian Cruise Line's 2027 Greek Isles program is built around 39 tracked departures between May 2 and October 13, 2027, split across Norwegian Gem, Norwegian Viva and a single long-haul voyage on Norwegian Sun. The defining feature of the season is its shape: every one of those 39 sailings is a one-way itinerary, with Norwegian Gem running a continuous 7-night shuttle between Venice (Ravenna) and Athens (Piraeus) while Norwegian Viva threads longer 8 to 10-night routes between Ravenna, Istanbul, Rome and Barcelona. That structure means the Aegean and the Adriatic show up on the same itinerary far more often than they would on a conventional round trip.

2027 Season Highlights

The season opens on May 2, 2027 with a Norwegian Gem 7-night run from Ravenna to Piraeus that calls at Mykonos, Kusadasi, Istanbul, Dubrovnik and Heraklion, and it closes with a Norwegian Viva 10-night Istanbul to Civitavecchia crossing departing October 13, 2027. In between, Norwegian Gem alternates two 7-night patterns almost every Sunday: southbound Ravenna to Piraeus by way of Mykonos, Kotor, Dubrovnik, Santorini, Olympia (Katakolon) and Corfu, then northbound Piraeus to Ravenna by way of Santorini, Olympia, Corfu, Kotor, Split and Koper. Twenty-two of the 24 Norwegian Gem sailings follow one of those two rotations.

Norwegian Viva's 14 sailings are the longer-format option, ranging from 8 to 10 nights and connecting four different cities: Ravenna, Istanbul, Rome (Civitavecchia) and Barcelona. Two of them, departing July 21 and September 15, 2027, run west from Ravenna to Barcelona with calls at Kotor, Villefranche, Salerno, Livorno, Palma and Dubrovnik, which makes them the widest-ranging Mediterranean routes in the set. The outlier is Norwegian Sun's 21-night September 5, 2027 departure from Piraeus, which continues through the Suez region to Dubai and is a repositioning voyage rather than a Greek Isles cruise in the usual sense. Verify all itinerary details with Norwegian Cruise Line, since port sequences and call times change.

Why Choose the Greek Isles in 2027?

Greek Isles cruises earn their place by density: on a single 7-night Norwegian Gem itinerary you can wake up in Santorini, Olympia (Katakolon) and Corfu on consecutive days, then cross the Adriatic to Kotor, Split and Koper before disembarking in Italy. Very few cruise regions pack that many distinct cultures and landscapes into a week. For 2027 the one-way structure is the real differentiator. Because none of the 39 tracked sailings returns to its embarkation port, an NCL Greek Isles cruise doubles as a transfer between two cities worth visiting in their own right, which suits travelers who want to build a land stay onto one or both ends.

Departure-port variety helps as well. Athens (Piraeus) puts you inside the Aegean from day one, Venice opens the Adriatic route, Istanbul anchors Norwegian Viva's longest itineraries, and Rome links the Greek Isles to the western Mediterranean. Season timing matters too: the region is a strictly summer deployment for Norwegian in 2027, with nothing scheduled before May or after mid-October, so shoulder-month departures in May and October are the only way to see these ports outside peak crowds.

Port Breakdown by Departure City

Venice (Ravenna), Italy - 17 departures. The busiest embarkation point of the 2027 season, and the northern anchor of Norwegian Gem's weekly shuttle. Ravenna departures are typically 7 nights on Norwegian Gem, running south to Piraeus with Mykonos, Kotor, Dubrovnik, Santorini, Olympia and Corfu in the sequence. Norwegian Viva also starts three longer voyages here, including the July 21 and September 15, 2027 nine-night runs to Barcelona and 10-night crossings to Istanbul on June 13, August 8 and October 3, 2027.

Athens (Piraeus), Greece - 13 departures. Twelve of these are Norwegian Gem's northbound 7-night itinerary to Ravenna, calling at Santorini, Olympia (Katakolon), Corfu, Kotor, Split and Koper. Piraeus is the most convenient starting point if the Greek islands themselves are the priority, since Santorini falls on the first sea day of that pattern. The thirteenth Piraeus departure is Norwegian Sun's 21-night September 5, 2027 repositioning voyage toward the Arabian Gulf.

Istanbul, Turkey - 6 departures. All six are Norwegian Viva, in 9 and 10-night formats, running either west to Civitavecchia (June 23, August 18 twice, and October 13, 2027) or northwest to Ravenna (July 11 and September 5, 2027). These itineraries pair the Aegean with Sicily and southern Italy, adding calls such as Valletta, Catania and Salerno alongside Santorini, Mykonos and Kusadasi.

Rome (Civitavecchia), Italy - 3 departures. Norwegian Viva sails east from Civitavecchia on July 2, August 27 and August 28, 2027, in 8 and 9-night formats bound for Istanbul, with Malta, Kusadasi, Salerno, Catania, Santorini and Piraeus appearing along the way. This is the natural choice if you want to start in Italy and finish in Turkey.

Most-Visited Ports of Call in 2027

Counting every port call across all 39 tracked 2027 sailings gives a clear picture of which stops you are most likely to get. Note that because these itineraries are one-way, Athens (Piraeus) and Venice (Ravenna) appear both as embarkation cities and as intermediate calls, which is why they top the list.

Smaller counts round out the list, including Salerno and Rome (Civitavecchia) at 9 calls each, Catania at 7, Valletta at 5, and Rhodes, Bar and Livorno at 4 each. Port assignments and call times are subject to change, so always verify the final itinerary with Norwegian Cruise Line.

Month-by-Month Greek Isles Cruise Calendar for 2027

May 2027

The season opens with five Norwegian Gem departures on May 2, 9, 16, 23 and 30, 2027, all 7 nights. The May 2 sailing from Ravenna is one of only two that use the eastern variant of the route, calling at Mykonos, Kusadasi, Istanbul, Dubrovnik and Heraklion before reaching Piraeus. Late spring in the Aegean generally means milder temperatures and lighter crowds at Santorini and Mykonos than midsummer, though sea conditions in the Adriatic can still be breezy. Ships: Norwegian Gem. Destinations: Greek Isles, Adriatic. Duration: 7 nights.

June 2027

Six departures, as Norwegian Viva joins the deployment. Norwegian Gem continues its weekly alternation on June 6, 13, 20 and 27, 2027, while Norwegian Viva starts a 10-night Ravenna to Istanbul run on June 13 and a 9-night Istanbul to Civitavecchia crossing on June 23, 2027. The Viva itineraries add Rhodes, Thessaloniki, Bar and Valletta to the mix, ports the 7-night pattern never reaches. Ships: Norwegian Gem, Norwegian Viva. Destinations: Greek Isles, Adriatic, Turkey, southern Italy. Duration: 7 to 10 nights.

July 2027

Seven departures. Norwegian Gem sails July 4, 11, 18 and 25, 2027, and Norwegian Viva adds three: a 9-night Civitavecchia to Istanbul run on July 2, a 10-night Istanbul to Ravenna crossing on July 11, and the 9-night Ravenna to Barcelona westbound itinerary on July 21, 2027 that calls at Kotor, Villefranche, Salerno, Livorno, Palma and Dubrovnik. July is high summer across the region, so expect the warmest conditions and the busiest shore excursion demand of the year. Ships: Norwegian Gem, Norwegian Viva. Destinations: Greek Isles, Adriatic, western Mediterranean. Duration: 7 to 10 nights.

August 2027

The peak month, with 10 departures. Norwegian Gem runs five 7-night sailings on August 1, 8, 15, 22 and 29, 2027, and Norwegian Viva adds five more: a 10-night Ravenna to Istanbul on August 8, two Istanbul to Civitavecchia voyages both leaving August 18 (one 9-night, one 10-night), a 9-night Civitavecchia to Istanbul on August 27, and an 8-night version of that route on August 28, 2027. If you want the widest choice of dates and durations in a single month, this is it. Ships: Norwegian Gem, Norwegian Viva. Destinations: Greek Isles, Turkey, Adriatic, southern Italy. Duration: 7 to 10 nights.

September 2027

Seven departures, and the most varied month of the season. Norwegian Gem sails September 5, 12, 19 and 26, 2027; Norwegian Viva runs a 10-night Istanbul to Ravenna crossing on September 5 and the second 9-night Ravenna to Barcelona itinerary on September 15, 2027. Norwegian Sun's 21-night Piraeus departure on September 5, 2027 heads east and south toward Dubai, calling at Rhodes, Alexandria, Aqaba, Jeddah, Muscat and Abu Dhabi. September typically retains summer sea temperatures with somewhat thinner crowds ashore. Ships: Norwegian Gem, Norwegian Viva, Norwegian Sun. Destinations: Greek Isles, Adriatic, western Mediterranean, Red Sea and Arabian Gulf. Duration: 7 to 21 nights.

October 2027

Four departures close the season. Norwegian Gem sails October 3 and 10, 2027, with the October 3 Ravenna departure using the eastern variant that includes Kusadasi, Istanbul and Heraklion. Norwegian Viva runs a 10-night Ravenna to Istanbul on October 3 and the season's final voyage, a 10-night Istanbul to Civitavecchia departing October 13, 2027 that calls at Mykonos, Kusadasi, Salerno, Livorno, Catania, Piraeus, La Spezia and Santorini. Early autumn in the Aegean is generally still warm, though rainfall becomes more likely toward the end of the month. Ships: Norwegian Gem, Norwegian Viva. Destinations: Greek Isles, Turkey, Italy. Duration: 7 to 10 nights.

Ship Deployment

• Norwegian Gem - May 2 through October 10, 2027; 24 sailings, all 7 nights, alternating weekly between Ravenna and Piraeus. Carries the Adriatic-plus-Aegean combination that defines the season, with Santorini, Olympia, Corfu and Kotor on nearly every departure.
• Norwegian Viva - June 13 through October 13, 2027; 14 sailings of 8, 9 or 10 nights linking Ravenna, Istanbul, Rome (Civitavecchia) and Barcelona. The wider-ranging option, adding Valletta, Catania, Salerno, Rhodes, Thessaloniki and Livorno to the Greek Isles core.
• Norwegian Sun - a single 21-night departure from Piraeus on September 5, 2027, running through the Red Sea to Dubai. Treat this as a repositioning voyage with a Greek Isles starting point rather than a Greek Isles itinerary.

Deployments are announced well in advance but can be adjusted. Confirm the assigned ship for your date with Norwegian Cruise Line.

Planning Tips

• Plan for two cities, not one. Because all 39 tracked 2027 sailings are one-way, you will fly into one country and out of another. Open-jaw airfare and pre- or post-cruise hotel nights in both Athens and Venice are worth pricing early.
• Match the rotation to your priorities. The northbound Piraeus-to-Ravenna week front-loads Santorini and Olympia; the southbound Ravenna-to-Piraeus week leads with Mykonos and puts Dubrovnik mid-voyage. Pick the direction that puts your must-see port on a day you are willing to spend entirely ashore.
• Consider the shoulder months. With departures only between early May and mid-October, May and October are the only options outside peak summer heat and crowd levels at Santorini and Dubrovnik.
• Check documentation early for the Turkey calls. Itineraries touching Istanbul and Kusadasi may carry different entry requirements than the Greece and Italy portions. Requirements vary by citizenship and itinerary, so verify current rules with Norwegian Cruise Line and official government sources before you travel.
• Book tender ports deliberately. Santorini and Mykonos are the two highest-frequency Greek island calls in 2027, at 34 and 18 calls respectively, and both commonly involve tendering. Confirm arrival and all-aboard times with the ship, since they vary by sailing.
• Solo travelers should compare cabin categories. Norwegian Gem and Norwegian Viva both list studio inventory in the tracked data alongside inside, oceanview and balcony cabins, and the gap between categories on a per-night basis is often smaller than expected on longer itineraries.

How to Find the Best Deals on Greek Isles Cruises

Norwegian Cruise Line pricing fluctuates based on demand, booking time, and availability. Here's how to time your booking:

• Book early - Promotional fares are often available 12-18 months in advance, which for a 2027 Greek Isles season means the window is open now
• Monitor price drops - Fares change weekly; set up deal alerts to track your preferred sailings
• Consider shoulder season - May and October carry the lightest departure counts of the season, with 5 and 4 sailings respectively, and the lowest observed per-night figure in the tracked window came from an October 10, 2027 Norwegian Gem departure at approximately $314 per night for a solo traveler at single occupancy (subject to change)
• Compare the two Norwegian Gem directions - The northbound and southbound 7-night rotations visit overlapping ports at different points in the week and are frequently priced differently
• Weigh duration against per-night cost - Across the 39 tracked sailings, inside-cabin fares typically ran approximately $354-443 per night for solo travelers at single occupancy based on CabinSaver's own fare tracking as of August 2026 (subject to change), and the 7-night Norwegian Gem itineraries generally sat toward the lower half of that band while the longer Norwegian Viva crossings sat toward the upper half

Our deal finder shows real-time pricing across all 39 tracked 2027 departures, helping you compare fares for your preferred dates and ports.

Between a weekly 7-night shuttle, four embarkation cities, and longer crossings that reach Barcelona and Istanbul, the 2027 Greek Isles season offers more route variety than its 39-sailing count suggests. Solo travelers weighing the single supplement against those options may also want to understand why solo cruises are so expensive before comparing categories.

Frequently Asked Questions

When does the 2027 Greek Isles cruise season start and end?

Norwegian Cruise Line's tracked 2027 Greek Isles season runs from May 2, 2027 through a final October 13, 2027 departure, with no winter sailings in the region. August is the busiest month with 10 departures, followed by July and September with 7 each. Schedules are subject to change, so verify sailing dates directly with Norwegian Cruise Line.

Which ports do 2027 Greek Isles cruises depart from?

Four embarkation ports appear across Norwegian's 39 tracked 2027 sailings: Venice (Ravenna), Italy with 17 departures, Athens (Piraeus), Greece with 13, Istanbul, Turkey with 6, and Rome (Civitavecchia), Italy with 3. Every one of the 39 Norwegian sailings is a one-way itinerary rather than a round trip, so your return flight typically leaves from a different city than your arrival.

Which ships sail the Greek Isles for Norwegian in 2027?

Three ships appear in the tracked 2027 data: Norwegian Gem with 24 sailings, Norwegian Viva with 14, and Norwegian Sun with a single 21-night repositioning voyage that leaves Athens on September 5, 2027.

Because most itineraries are one-way, Athens and Venice appear both as embarkation points and as ports of call. Itineraries are subject to change.

How much do 2027 Greek Isles cruises cost for a solo traveler?

Based on CabinSaver's fare tracking as of August 2026, inside-cabin fares on the 39 tracked 2027 Greek Isles sailings typically ran approximately $354 to $443 per night for solo travelers at single occupancy, which includes the single supplement (subject to change).
