Where do you recommend visiting in the Baltic states?

Q I’m meeting my wife at the end of an academic conference in Tampere, Finland, next August.

We are planning a couple of days in Helsinki, followed by the ferry to Riga. We have a couple of weeks in total and would like your favourite recommendations for the Baltic states - ideally ending up somewhere on the coast for a few days. We plan to travel by public transport. A What a well-timed conference. You will be in the eastern Baltic at the time of year when the sea is at its warmest (though at least 10 degrees celsius lower than the Caribbean). The days will be long, too, allowing you plenty of time to see one of the most fascinating corners of Europe.
