The Third Man

Chase The Third Man? While Carol Reed's classic post-war film noir actually takes place in Vienna, you can recreate its dark atmosphere by taking a guided tour of Basel's underground sewerage system (don't worry, this being Switzerland, it's not overly smelly). After entering a tunnel at Heuwaage, you follow the Birsig river underground to its estuary in the Rhine. The 1 hour 15 min tour ends at Restaurant Safran-Zunft in the city center, where you are taken up into the light again - and to tasty snacks. The tour requires a group to justify the somewhat high cost of Fr. 250 (per group, not person); you should either find like-minded folks or try to join an existing group. Contact the urban planning firm Lindenberg 3,, for details and reservation.

Basel Herbstmesse
autumn fair
Two weeks beginning on the last Saturday of October every year. Rides, booths, shooting alleys and lots of food in several locations all over the city, including Messeplatz (biggest site with most attractions, including rollercoaster and the like), Barfüsserplatz and Münsterplatz (where you get nice views from the Ferris wheel). Recommended: the cosy market at Petersplatz, near the main University building, where you can take a leisurely stroll and buy almost anything you never needed - from china, spices and tea, hand-drawn candles, knitted sweaters, leather goods to the latest household cleaning tools - and of course tons of tasty fast food, from healthy corn on the cob to less healthy Wurst varieties.

Basel ferry
The Basel Rhine ferry is an icon of the city and a visit to Basel without a ride on a ferry would be incomplete. It only takes two-three minutes but it offers a great view (during sunshine).

BaselWorld
International Watch and Jewelry fair. Late March-Early April. The world's biggest watch and jewelry trade show. The city's population more than doubles during this convention. The watch displays are particularly elaborate, with the exhibition space set up like an indoor version of New York's 5th Avenue.

Chienbäse
Combine Fasnacht with the amazing fire spectacle of Chienbäse parade in nearby town of Liestal, capital of the neighboring canton Basel-Landschaft (15 minutes by train from the SBB Station), which starts at 19:15 on the Sunday evening preceding Morgestraich. Locals clad in (kind of) fireproof garb parade through the narrow and spectator-lined streets of the town, carrying large burning wooden brooms (bäse) above their heads. Other groups are drawing iron carts with huge bonfires - which they even rush through some of the old town gates, as the flames lick the structures above. There are a number of inconclusive interpretations of this pagan-seeming custom but, again, you don't necessarily need to understand any of them to appreciate the eerie and even mildly threatening beauty of the parade.
