The easiest way to get to Tartu from abroad is via Tallinn. To reach Tartu from the Tallinn airport, you can take a bus (Lux Express; buy beforehand) directly from the airport or a train (Elron; can be bought on the train) from Ülemiste station (a 10-minute walk from the airport). Both are excellent options. Riga is also an option, but there are only minimal bus connections to/from Tartu (Lux Express; buy beforehand).
Arriving late at Tallinn airport or leaving early from Tallinn airport typically requires spending the night in Tallinn, so make sure to check the bus/train schedules and find a place to stay in Tallinn, if necessary (the Mercure hotel is a five-minute walk from the airport).
Tartu is small enough that you can walk everywhere within 30 minutes. For other options, see:
