Warsaw and Vilnius sit at the southern and northern ends of the old Polish-Lithuanian Commonwealth, and that history is still visible in both cities. They're not the easiest combination logistically, with no fast direct train, but the overnight bus connection makes it workable without losing a full travel day.

Why This Combination Works

The shared history of Poland and Lithuania runs deep: Vilnius was part of Poland for much of the 20th century, and the Jewish heritage of both cities overlaps in ways that make visiting them together genuinely illuminating. Beyond the history, they're both underrated by Western European standards and significantly cheaper than equivalent trips to Paris or Amsterdam. Travellers who enjoy cities that haven't been completely packaged for tourism will get a lot out of both.

For a 8-day trip: 4 nights Warsaw, 4 nights Vilnius. Even split works because neither city is dramatically larger than the other in terms of what's on offer for visitors.

For a 6-day trip: 3 nights Warsaw, 3 nights Vilnius. Solid and manageable. Include the overnight bus and you only lose one evening.

For a 5-day trip: 2 nights Warsaw, 3 nights Vilnius (or the reverse). Vilnius gets the nod for the extra night because it's slightly more compact and easier to explore thoroughly.

Getting Between the Cities

There is no direct fast train between Warsaw and Vilnius. The bus is the main option. Lux Express and FlixBus run the route in 8 to 9 hours. Overnight departures are the practical choice: you board in the evening and arrive in the morning. Cost is 20 to 40 euros. The overnight train exists (via Belarus historically) but direct services are limited and routing is complicated. The overnight bus is the standard move.

Which City to Visit First

Start in Warsaw. It's better connected internationally by air, and Warsaw to Vilnius is slightly more intuitive as a northward route through the old Commonwealth territory.

What Each City Adds to the Trip

Warsaw

Warsaw gives you the capital city experience with historical weight: the Warsaw Rising Museum, the POLIN Museum, Lazienki Park, and the rebuilt old town. The city moves fast, has strong food and nightlife, and is easy to navigate. Two days covers the core; three days gives you room for the Praga district and Wilanow Palace.

Vilnius

Vilnius delivers the baroque old town, the Uzupis bohemian district, the Gate of Dawn, and the Hill of Three Crosses viewpoint. It's a quieter, more contemplative city than Warsaw, and cheaper. The Paneriai memorial site outside the city, where 70,000 Vilnius Jews were murdered during World War II, is a significant and sobering excursion that is directly relevant if you've visited POLIN in Warsaw.
