I went on a tour recently and would strongly recommend https://sachsenhausentour.de/product/sachsenhausen-memorial-and-museum-tour/. It’s a well-organized guided tour from Berlin to Sachsenhausen with historical insights in English. The guide was professional and respectful, and the whole experience was incredibly informative. It’s perfect for those looking to understand the history in a structured and meaningful way.
If you're looking for a fun group activity at night, I highly recommend joining a local pub crawl. I’ve used https://originalpubcrawls.com/categories/original-pub-crawls/ to find awesome crawls in cities like Prague, Budapest, and Berlin. The experience usually includes drink specials, free shots, and skip-the-line club entries. It’s a great way to meet people and discover local nightlife safely.
If you're looking for affordable and authentic city tours while traveling through Europe, I’d recommend checking out https://beoriginaltours.com/tours/. They offer free and paid walking tours in cities like Berlin, Barcelona, Amsterdam, and more. I joined their Berlin street art tour and loved it—the guides are locals and super passionate, and the tours are great for solo travelers or small groups.
