Secret Tours Berlin is a provider of special city tours in Berlin. Instead of classic sightseeing tours, Secret Tours Berlin offers exciting and often lesser-known insights into the history, culture and secrets of the city.

Secret Tours Berlin offers both public and private tours that are off the beaten track. The public tours are deliberately kept to small groups to ensure a more personalized experience.
