This new river-to-sea journey from Venice to the Greek Isles is the ultimate summer upgrade

Seabourn and Uniworld have joined forces to sail you from Venice to the Greek Isles aboard two elegant ships.

There’s nothing quite like spending summer in the Mediterranean, swimming in turquoise waters, admiring the cinematic coastline, and basking in the effortless allure of life lived under the sun. A new way to make the most of summer in the region is now possible thanks to an exciting partnership between Seabourn and Uniworld Boutique River Cruises – sailing from Venice to the Greek Isles on not one, but two luxury ships.

Explore Croatia, Montenegro and the Greek Isles aboard the luxurious Seabourn Quest.

The first collaboration between luxury ocean and river cruise lines, the new Venice & Mediterranean Sea journey offers a combined itinerary across 15 days of pure luxury and immaculate summer vibes. The collaboration is a no-brainer, with both brands offering all-inclusive luxury, small-ship intimacy, high-end service and rich cultural depth. 

This partnership offers travellers a unique opportunity to experience the best of both worlds: the intimate nature of river cruising with the expansive journey of ocean cruising – because why not have both? The adventure also includes exclusive experiences such as a private after-hours visit to St Mark’s Basilica and a wine tasting at Domenico di Baglio, one of Europe’s oldest wine estates.

Your journey begins with eight days aboard the 126-capacity S.S. La Venezia, which sails directly through the romantic Venetian Lagoon. Along the way, you’ll visit iconic landmarks such as the Doge’s Palace and the Rialto Bridge. Chanelling the grandeur of early 20th-century Venice, this dreamy vessel is outfitted with opulent Murano glass, sumptuous Fortuny fabrics, gilded accents and intricate mosaics. Expect elegant staterooms and French balconies to watch the world go by from.

You’ll then sail to the scintillating Italian islands of Burano, Mazzorbo and Torcello, exploring quiet canals and Renaissance cities, savouring regional dishes and enjoying curated excursions in elevated Uniworld style. 

Next, head to the open sea and step aboard the yacht-like Seabourn Quest with its luxurious oceanfront suites and open bars. The seven-day adventure to Greece includes mesmerising stops in Croatia’s historic towns of Vodice and Primošten, as well as Montenegro’s idyllic Bay of Kotor. Arriving in Greece, you’ll explore the sun-drenched islands of Corfu and Cephalonia, and meander around the historical streets of Nafplion and Piraeus. Summer has never looked so good.
