Be prepared to have your mind bent, blown and rewired as you walk into the Lange Voorhout Palace where the illusory work of famous graphic artist M.C. Escher is exhibited. The palace is home to such legendary Escher paintings as 'Air and Water' in which birds are blended into fish and 'Waterfall' in which water appears to flow upwards instead of down. There are interactive experiences on the second floor, dedicated to the Eye of Escher where guests are encouraged to solve some of Escher’s most perplexing mysteries, including the impossible Penrose Triangle. On the third floor, there is a large-scale optical illusion where adults can appear to be children and vice versa. Audio tours and guided tours are available and there are additional temporary exhibitions taking place on occasion.

You can surf right in the heart of the city at Eisbachwelle. For over 40 years, this spot has been a magnet for both surfers and spectators. It's known worldwide as the most consistent, biggest, and best river wave in an urban setting. Just a heads up, though — it's really only for highly skilled pros. The waves are tricky and can be dangerous, so it's not the place for beginners. But even if you're not up for surfing, it's definitely worth stopping by to watch the experts show off their moves.
