Let’s walk from the lungs to the heart through a large vein-corridor. Or no, wait: maybe first look inside the head to examine the brain. Corpus is a very special museum near Leiden where you are guided through the human body and learn everything about how everything works. You don’t often get the opportunity to have such a peek, do you? A tour in Corpus lasts 55 minutes. The museum is best reached by taking the train to Leiden and from there the bus to Oegstgeest. On the way back, stop in beautiful Leiden for hutspot, a typical dish of the city containing potatoes, carrots and onions.
