Via Baltica, officially known as European route E 67, goes from the Estonian capital Tallinn to the Polish capital Warsaw. It is the most important highway between the Baltic States, and fairly important for traffic from Finland and Russia to Central Europe as well as the other way around. Some travel brochures exclude the Polish part of the road, and end the road in Kaunas or at the Polish-Lithaunian border.
The distance from Tallinn to Warsaw is about 970 kilometers, not including any detours. The road is mostly two-lane highway and it is possible to drive the whole way in less than 24 hours but plan for at least three days if you want to see more than just the road. The overwhelming part of the travellers drive, but it is also possible (but uncommon) to go by bus.
Documents and regulations
All the countries are Schengen countries, that is there are no regular border inspections and people from most of Europe do not need any visa. However, authorities may stop your vehicle in order to check your travel documents and the registration documents of the car. More information about entering the individual countries are to be found in their articles. Travelers should observe that it is mandatory to have a first-aid kit and a fire extinguisher in the vehicle in the Baltic countries. Good maps are invaluable especially in bigger cities.
There are hotels and campings along the road.
At this point Estonia, Latvia and Lithuania use euro as their currency. Poland has its own currency (zlotys), though in some hotels it is possible to pay with euros. The price level is slightly lower than in Western Europe, however imported goods of international brands like cost the same or more than in Western Europe.
If you can't speak the local languages Estonian, Latvian, Lithuanian or Polish, keep yourself to larger establishments and larger cities where it is comparatively easier to communicate in English than in the countryside. In hotels there is generally always someone who speaks English. Some basic knowledge of Russian is useful, one should however not assume that everybody understands or wants to speak Russian. German becomes more common towards the southern end of the trip, however don't count on that.
Generally the Baltic countries are safe as long as you use your common sense. Car thefts and burglaries are unfortunately more common in this part of Europe, but as long as you don't leave any valuables on display the risk is small. In the night it is also good to choose a hotel with guarded parking or a camping. As elsewhere in Eastern Europe and in Poland some people tend to drive fast and take great risks, sometimes there are four cars beside each other on a two lane road. The best tip is to keep calm and drive on the right side, however, one has to look out for pedestrians and bikers.
If your trip ends in Warsaw you can continue to the country's second largest city, Krakow, along the E67 to Prague or to Berlin. If you end your trip in the northern end you can continue to Helsinki or Stockholm by ferry or to St.Petersburg by road.
