We spent a good couple of hours enjoying the Zeppelin Museum in Friedrichshafen today. Before I begin - Friedrichshafen is a very busy city, so it's probably more relaxing to arrive by bus, boat, or train. All of them stop right outside the museum. Driving is pretty busy in the city, but if you do drive, there is a large car-park next door.
This is a wonderfully interesting museum on the history of airships in Europe starting in the late 1800's, their use in WW1, luxury travel in the 30's, and the fate of the Hindenburg. There's lots of detail for those who want to know all there is to know about airship development, and just enough for those who want a "cole's note" version. There is both english and german information throughout the museum.
When you're finished, you can walk the promenade along the lake, enjoy the fabulous views of the Swiss Alps, and enjoy watching all the folks riding their bikes or embarking from the various ferries. It's too bad we didn't have time to enjoy it for long - maybe next time!
