In August 2006 we took the bus from Riga (Latvia) to Tallinn in Estonia. 300 km in 6 hours, but only 14 € cost. Landscape is flat, wooded, poor soil, stony and lonely. I liked Tallin very much, modern culture and well tidied up. Pubs very pleasant.
2017 with Klaudi 3 days in the Baltic States, by plane to Riga, by car to Lithuania and Estonia.
