Wieliczka Salt Mine
 

Hey, did we forget to mention the salt mines - a UNESCO world heritage site near Krakow..?

In case you feel like a change from the military history.

YES! Check concert dates...

Maybe you should go through Eagle Nests Trial? I've never been there but it look pretty nice if you are intrested such a travel:)
Here you have a couple of websites
Szlak Orlich Gniazd - Wikipedia, wolna encyklopedia in polish but there are some pictures
Szlak Orlich Gniazd map of Eagle Nests Trial
FORTYCK.PL - Fort 44a Pêkowice it is web page about Kracow Stronghold unfortunately in PL language
Also if you plan to travel near Warsaw visit Modlin Stonghold
Modlin Fortress - Wikipedia, the free encyclopedia
Have a nice trip :D

The area near Rastenburg is called the Masurian Lakes, well worth a few days of idling along quiet country lanes. The castle at Malbork is pretty impresive, at one time the largest brick built building in the world. The Elblag canal which carries boats overland on cradles is worth a look, there's a camp-site on the canal on the edge of Elblag which is run by a really friendly old chap. The facilities are top notch for Polish camp-sites which isn't really saying much, it's not worth lugging the gear all that way when decent, cheap hotels abound. The Hel peninsula near Gdansk is definitely worth exploring for a few days, it's the point where the first shots of WW2 were fired. The town of Hel is a quaint fishing port with ferry or train links into Gdansk. As mentioned in previous posts Stalagluft 3 at Sagan (now Zagan) is worth spending an afternoon finding.

Thanks for all the suggestions guys, I have located the various places with Mapsource/Google Earth and incorporated them on my route. Fortunately I have quite a long time available to do all this.

I hope that's not too late for suggestions.

So I think that if you are interested in WWII you should see also Warsaw (however the city itself is not so spectacular). We have here the best history museum (new style). It's about the Warsaw Uprising in 1944 - check the site Warsaw Rising Museum Also a huge Jewish and Catholic "Powązki" cementery here with beautiful sculptures and a lot of history. ...and the lovely Palace of Culture (our biggest gift from Stalin) - the only one in Poland. In old USRR the have a lot of them everywhere.

You should also see the Hel peninsula with some germans fortifications, bunkers and rocket launchers. Near Łeba you can see the old german polygon in Rębka with V1 and V2 rockets launchers - eg. RHEINNTOCHTER

If you need a garage in Warsaw I have one. I can also show you around if I have time. Have a nive trip in Poland! Do not forget to buy enough Żolądkowa Gorzka - Wódka ¯o³±dkowa Gorzka ;)
