Top marks for Berlin's 100 bus
From Zoologischer Garten to Alexanderplatz, Berlin's 100 bus winds its way past many of the city's top sightseeing attractions.
Kurfürstendamm? Check. Tiergarten? En route, too. Not to mention the Reichstag, Brandenburg Gate, Museum Island and Berlin's iconic television tower.
The double-decker vehicles provide optimum viewing opportunities, although admittedly you'll need to be lucky to bag a premium seat at the front of the top deck.
But best of all, perhaps, is the fact that since this unofficial bus tour is part of the regular public transport system, it'll cost you nothing more than a standard single ticket.
And because these always include up to two hours of travel time (click here for more details), you're effectively purchasing a hop-on, hop-off deal that's perfect for a budget perusal of Berlin's main attractions.
How's that for a top-scoring tourist tip?
During peak tourist seasons the 100 bus can get crowded, but the 200 route (which also travels between Zoo and Alexanderplatz) offers a good sightseeing alternative.
