Interesting places
 

Hey there,
We will be traveling on motor bikes from the UK into Europe sometime in July via the ferry to France and from there through into Germany and up into Sweden and Norway, Finland down into Russia and heading east to the Urals and possibly beyond then heading south and then west back into the Ukraine and then meandering back to the UK through the more interesting countries.
While planning? this trip I need to know if anyone has any recommendations for interesting places to visit?
We would prefer to look at things such as places of industrial interest like Chernobyl and places where interesting things have happened like Auschwitz.
The route is flexible and if anyone has any suggestions that would be good.

Curonian Spit, Auschwitz/Birkenau, Berlin, Tallin, Riga, Vilnius.

Poland
The Solidarity museum in Gdansk. There is a good campsite in Sopot (called ‘Kamienny Potok’) five minutes walk from the station with trains every fifteen minutes to Gdansk.
Wilczy Szaniec (Hitlers Wolf’s Lair) in the north east corner. There is a hotel in a converted bunker at the Lair itself as well as a basic campsite.
Lithuania
The statue park (Gruto Parkas) is well worth a visit and there is a campsite in nearby Druskininkai.
The Hill of Crosses near Siauliai.

You might want to visit Peenemunde . I hope to either this or next year.... BMW/Enfield :)
