21-Day Europe backpackr Itinerary: London to Vienna

How much does 3 weeks in Europe cost for a backpacker hitting the major capitals? On this six-city route from London to Vienna, the answer is about $40 per day, which adds up to roughly $840 over 21 days for food, accommodation, and local transport (not counting intercity travel). That average masks real variation: London and Paris push daily costs to $50 to $60, while Prague and Berlin bring them back down to $25 to $30. The math works because the route deliberately mixes expensive and affordable stops. All prices on this page are in USD.

The itinerary threads six cities that each justify their spot. London delivers world-class museums (most are free), theater, and a food scene that has quietly become one of Europe's best. Paris is the art and architecture capital, with the Louvre, Musee d'Orsay, and neighborhood bakeries that make $2 croissants taste like a life achievement. Amsterdam combines canal-side charm with a cycling culture that makes the city feel smaller than it is. Berlin is history, nightlife, and the best doner kebab value on the continent. Prague has $2 beers, a medieval old town, and a creative energy that rivals cities three times its size. Vienna closes with coffeehouse culture, classical music, and Hapsburg grandeur.

Hostel prices across these six cities show the full European spectrum. London dorms run $30 to $45 per night, making it the most expensive bed on the route. Paris is close behind at $28 to $40. Amsterdam sits at $25 to $35. Then the relief kicks in: Berlin offers quality dorms at $15 to $22, Prague at $12 to $18, and Vienna at $18 to $28. Booking a few days ahead in London and Paris is essential during summer. In Prague and Berlin, walk-in availability is common even in peak season.

Ground transport between the six cities totals $750 to $950. The key money-saving moves are FlixBus connections (London to Paris from $15, Berlin to Prague from $12) and overnight buses that double as free accommodation. Food costs follow the same pattern as accommodation: London and Paris require discipline (grocery store lunches, market food), while Berlin's street food scene makes $5 meals easy and Prague's restaurant prices feel like a rounding error compared to the first two stops.

Three weeks is enough time to give each city real depth without rushing. A functional split is four days in London, three in Paris, two in Amsterdam, four in Berlin, four in Prague, and four in Vienna. That leaves buffer days for travel and the inevitable moments when a city earns an extra afternoon. The route flows west to east, getting cheaper as it goes, which means the budget relaxes right when travel fatigue might otherwise set in.
