Kjellersmauet is too narrow and steep for driving by car to Claus Ockenssmauet 3. The closest place is the outer Markevei 1 on the Hol Berg public (link to Google Maps).
the airport bus is fastest and rimeligiste transport is second by taxi. From the Lido corner between the public square and the fish market several times an hour. It’s 700 yards to go and take 9 minutes. Here you will find directions.
Beffenfergen is a charming little ferry. Timetables can be found here.
