Buy an ABC ticket for the airport
BER airport sits in fare zone C, so get a 72-hour ABC ticket from a BVG machine or the BVG app to cover your arrival, departure and city travel. Paper tickets must be stamped in the red or yellow validator before your first ride, and plain-clothes inspectors fine 60 EUR on the spot.
Carry some cash
Cards are much more widely accepted than a few years ago, but many Kneipen (traditional pubs), Spaetis, doener stands and some club doors are still cash only. Keep 40-60 EUR on you and use bank ATMs rather than standalone Euronet machines, which charge high fees.
Tipping and the bottle deposit
Round up or add 5-10 percent in restaurants by telling the server the total you want to pay rather than leaving cash on the table. Most bottles carry a Pfand deposit of 8-25 cents, which you can return at any supermarket machine.
Book the Reichstag dome early
Visits to the Reichstag glass dome are free but require advance registration on the Bundestag website, and slots often fill several days ahead. Museum Island venues such as the Neues Museum also use timed tickets, so reserve online in high season.
Know the club door rules
At Berghain, Sisyphos or Tresor, arrive in small groups, dress down in dark casual clothing, stay quiet in the queue and know who is playing. Photos are banned inside most clubs and stickers are put over phone cameras; Saturday night often runs well into Sunday afternoon.
Best time to go
May to September is the best season, with long days, 20-28 C temperatures and open-air beer gardens and canal bars. Winters are grey and around 0-5 C, though December's Christmas markets at Gendarmenmarkt and Charlottenburg Palace are a highlight.
Watch your bags in busy spots
Berlin is generally safe, but pickpockets work Alexanderplatz, Warschauer Strasse, the U8 line and crowded S-Bahn trains. Ignore clipboard petitioners near the Brandenburg Gate, a common distraction scam.
Plan around Sundays and Mondays
Almost all shops and supermarkets close on Sundays, so stock up on Saturday or use station shops and Spaetis. Many museums close on Mondays, so put Museum Island visits on other days.
