Münster Botanical Garden sits directly behind the Schloss and belongs to the university, which gives it a calm, lived-in academic feel. The grounds mix formal beds, old trees, ponds, and greenhouses, all within an easy walk of the old town.
It is not a blockbuster garden, but it is one of Münster's nicest pauses. Come between museums or after cycling the Promenade ring, and use it as a quiet reminder that this is as much a university city as a historic one.
