By air: Friedrichshafen Airport (FDH) is 4 km north of the city centre and has flights to major German hubs (Frankfurt, Munich) plus a handful of European destinations. Bus line 7394 connects the airport to the city in about 15 minutes. The airport is small enough that check-in rarely takes more than 20 minutes. Zurich Airport is the main regional hub for more flight options and is about 75 minutes away by car or train via the lake ferry.

Direct trains run to Stuttgart (about 2.5 hours), Ulm (around 1.5 hours), and Munich (around 2 hours with a change). The main station for long-distance services is Friedrichshafen Stadt; Friedrichshafen Hafen station is smaller and is mainly used for the ferry connection.
By ferry from Switzerland: The car ferry from Romanshorn (Switzerland) to the Friedrichshafen harbour dock runs several times daily throughout the year and takes around 45 minutes. It is the most direct route from the Swiss rail network. The Romanshorn ferry landing is directly in front of Romanshorn station. Foot passengers and cyclists are well catered for; cars can also travel with advance booking in summer.
