One of the best walking tours I have ever been on. It's around 4 hours long, which feels a bit…read moredaunting on paper, but by the end I was wishing for it to have another few hours.
Berlin is a city that you could have 4 days and barely cover the basics, so I am so impressed with OBW for squeezing so much history, culture, and art into 4 hours.
The tour covers many different areas and eras of Berlin, and I think it is a must do for any first time visitors to Berlin. Really helped me find my footing of Berlin's history, culture, and geography.
