Beyond the flora, the island of Mainau's other colorful extravagance is Das Schmetterlinghaus, Germany's largest butterfly conservatory. On a circular walk through a semitropical landscape with water cascading through rare vegetation, you'll see hundreds of butterflies flying, feeding, and mating. The exhibition in the foyer explains the butterflies' life cycle, habitats, and ecological connections. Like the park, this oasis is open year-round.
