Why Berlin is worth visiting
Berlin carries its twentieth century history openly, from the Cold War scars along the East Side Gallery to the rebuilt Reichstag dome that turned a former parliament into a public landmark. Reunified since 1990, the city keeps two very different downtowns instead of one, plus a museum collection recognised by UNESCO and a nightlife scene that never quite decides when to close.
Neighbourhoods to know
Mitte holds the historic core: the Brandenburg Gate, the government quarter and Museum Island, all walkable from each other. Kreuzberg and Friedrichshain, across the river, keep the alternative edge of reunified Berlin, with the East Side Gallery, canalside bars and street art. Charlottenburg, further west, is City West, built around Kurfurstendamm's shopping and the baroque palace. Prenzlauer Berg mixes restored townhouses with Mauerpark and its Sunday flea market.
When to go and for how long
May to September brings the longest days and outdoor beer gardens, with June to August the busiest and warmest stretch. Spring and autumn stay mild with thinner crowds, and December fills Gendarmenmarkt and Alexanderplatz with Christmas markets. Three to four days cover the historic centre and one of the outlying districts at an easy pace.
Getting around
The U-Bahn and S-Bahn networks reach almost everywhere on a single BVG ticket that also covers trams and buses, with day passes covering unlimited rides. Central Mitte stays walkable between its main sights, and bike lanes make cycling a realistic way to cover the wider city.
