Friedrichshafen is located at the northeastern corner of Lake Constance (Bodensee), near the lake's widest point in the German federal-state of Baden-Württemberg. This mostly modern city was almost completely rebuilt after bombing in World War II. It has one of the longest waterfront promenades of any town along the lake. It also has a nice view of Austria and Switzerland and the alps across the lake on a clear day. In addition, the town's other highlights are three interesting museums and the dome-capped Schlosskirche, the premier remaining reminder of Friedrichshafen's baroque past.
Friedrichshafen's small international airport  with direct flights from Dublin, London, Berlin, Prague. From the airport's train station, there are regular commuter trains to Friedrichshafen (or in the opposite direction to Ravensburg and an hourly service to Ulm). A cab from the airport to downtown will cost between € 10-15, depending on where you go.
You could also consider to fly to Zurich/Switzerland and take one of the hourly trains to Romanshorn and take the ferry over the Lake of Constance. Since the last ferry in the offseason period leaves around 19:30h this is not an option for late arrivals.
There is a regular train service from Stuttgart and Ulm to Friedrichshafen. Another train line runs along the Lake of Constance (though mainly inland and not very scenic) from Lindau via Friedrichshafen to Radolfzell, Schafhausen and Bale. In summer time, the trains to and from Friedrichshafen might be crowded with groups of cyclists (making the long-distance travel to the lake on the train).
The town of Friedrichshafen covers a fairly large area along the lake side and the hinterland. There is public transportation, esp. a fairly priced night-bus system, but the best way to get around is by bike or car. During high-season in summer roads can get quite crowded and traffic jams getting in and out of Friedrichshafe are frequent. In particular on the B31 (Lindau-Friedrichshafen-Immenstaad-Hagnau-Meersburg-Überlingen).
There are plenty of opportunities to rent bikes in Friedrichshafen.
Sights and museums
Rent a bike or bring your own and cycle along the lake to Meersburg (in the west) or Lindau (in the east). It is also fairly popular to do a tour around the entire lake in one (sportive with shortcuts), two (reasonable), three or more (leissure)days.
There are probably more scenic locations along the lake where you can do canoeing, but there is a canoe rental in Friedrichshafen and they also organise tours on one of the small tributaries into the Lake of Constance. Canoe rental
Besides an indoor climbing facility by the DAV (Deutscher Alpenverein)for its members and affiliates see website for details, there is a "adventure park" in nearby Immenstaad (about 12km from Friedrichshafen) that is more geared to families, children or groups on a team building exercise.
