Baltic Ideas?

Sounds like a good idea! Where are you flying from? How much time do you have and how do you want to spend it?

Which transportation option is the best depends on where you are going. Ferries are a great option across the Baltic sea, trains are a good option on land and in the Baltic states, buses are often a good option.

March is not the best time to travel that far north due to cold temperatures. Tallin's average low temperature is 25 degrees F and the average high temperature is 37 degrees f. Over 20 days in March either have rain or snow.

We love Tallin in the Summer as it's a very lush, green place due to melting snowfall. But that early in the year I'd be catching RyanAir to somewhere warmer--like Rome. AirBaltic also flies to most of the major European cities from Tallin.

Note: We've been to all the Baltics including St. Petersburg and Norway. The best traveling that far north is from June to the first 2 weeks of September. It's not only temperature, but precipitation, wind and sunshine must be considered.

Yeah, the weather may or may not be awesome, so do be prepared for cold/wet in case you don't get especially lucky.

That said, consider renting a car, as it is the best way to efficiently reach parts of all three Baltic countries outside the main tourist centers (most tourists only go to the capital cities, and while they are great, there's lots more outside of them). There are plenty of good things to see/do in each of the three countries to fill two weeks (shhhh, they are overlooked gems).

What the best time is to travel to a certain place can be debated, but I don't think March is a bad time to travel to the Baltics. Also note that neither Norway, nor St Petersburg are in the Baltics.

And, the Estonian capital is spelled TALLINN! That is important to remember.

Keep in mind that ferry connections cover the Baltic, depending on the geographic extent of your travels.

Aside from the three Scandinavian countries connecting to each other by ferry, from Sweden to Poland is a ferry connection or two, likewise between Helsinki and Germany, Germany and Oslo, and also Germany to Lithuania, plus Germany and Poland. Y

Bottom line ...you have numerous ferry options.

There are FlixBus and Econolines buses from Tallinn to Riga and Riga to Vilnius. A random date in March shows each FlixBus ticket as less than $20. In the past, I found that some of the "extras" (baggage and seat selection) were cheaper in almost any other currency than dollars.

For bus travel I'd recommend Lux Express instead of Flixbus. https://luxexpress.eu/en/

My advice to you would be to go to more than the capital city in each country, but since you are traveling in March, I would avoid the resort cities along the coast. They might be pretty dead. Check before you go.

For transportation, train routes are more limited. We used the train a couple of times in Lithuania and Latvia ( also limited destinations in Estonia but we did not use the train there). The bus system is extensive and easy to use. You can look at schedules and prices on the internet and even buy tickets.

Be careful about opening hours. We were in Estonia in September and the web was not always reliable when it came to opening schedules. Tourist destinations were changing from summer to off-season schedules in September and we had some confusion.

I would not include Poland. With only 2 weeks, I would stick to the Baltic countries. We spent 10 days in Lithuania, 6 in Latvia on one trip. We were there in the summer. We spent about 9 days in Estonia and 6 in Finland on another trip. Poland needs more than 2 weeks. There are frequent ferries between Helsinki and Tallinn.

I really loved our trips to these countries and hope you have a wonderful time.

If the itinerary ends up with visiting the Baltic countries, are you including Lithuania? If so, I suggest Klaipeda, if you want to get into the history.

In August 2007, I went to a Yiddish class in Vilnius, Lithuania that I got college credit for. The old town and perhaps the surrounding neighborhoods too, in Vilnius, is a good city. There is the restored 3-storey tower of a castle on a hill that you can pay to go in; the ruins of another castle; I vaguely going to some kind of archaeology/history museum; multiple historic churches; there is a Jewish/holocaust museum; you could check to see if you can get a Jewish themed and/or generic not-jewish-specific English guided walking tours. There are plaques in Yiddish; you need to know where to look for them or you are likely to miss them. There may be a kgb museum in the basement of a building, where soviet authorities tortued people... possibly a royal palace - I don't remember seeing it; when I was there they were building a replica of a royal palace that is supposed to be an event venue and/or museum. Check a guidebook. I was on a guided tour in Kovno (Kaunas)... I didn't make time to go other places in the baltics... look up the Trakai castle in Lithuania; Riga, Latvia; check the Lonely planet guidebook; see if there is a Rough Guide; Tallinn is supposed to have a well-preserved medieval neighborhood. Lithuania is pleasantly uncrowded; I would go back (as a tourist, not to spend more money on a class).
