With so many, there's always one nearby. Sit down and listen to the audio guide as you pass by the most important monuments, and when you see something you like, hop-off and explore at your own pace. Get a full uninterrupted tour by hopping on board and staying seated for the full 2.5-hour bus tour. From the Brandenburg Gate to Potsdamer Platz and from the Berlin Zoo to the Reichstag, you’ll see it all. At SEA Life Berlin, discover the world under the water, with octopuses, jellyfish, clownfish, and 5000 other sea creatures. See how tropical reefs are formed and support life, or feel the tickling of cleaner shrimps on your skin when you hold your hands in the touch pool. Take an underwater journey by following aquatic life from the Spree river to the depths of the Atlantic ocean. You can watch as the animals are fed by supervisors and try to guess their favorite food and also learn how you can help prevent pollution.
