Driving from Warsaw thru the Baltics
I'll be driving from Warsaw, Poland on my way towards St. Petersburg, Russia but will be driving through Belarus, Lithuania, Latvia, Estonia, and Finland prior to entering Russia.
Are there any other cities aside from the capital cities of Minsk, Vilnius, Riga, Talinn, and Helsinki to visit in these countries? I'll be driving so any scenic roads or drives are welcome and time is not an issue. Is the Russian territory of Kaliningrad worth a visit?
I'd also love any and all recommendations of places to go,. see, excursions, etc in any of these countries. Much obliged!
