The name Mainau immediately conjures up visions of fabulous flower displays – the lake’s third-largest island is famous far and wide.  Visitors to the beautiful 45-hectare island find themselves transported to a Mediterranean oasis. It is a place for strolling, relaxing, admiring and exploring.

The one-kilometre-long island is owned by the aristocratic Bernadotte family, who originally came from Sweden. The family still lives in the castle on the island to this day. And while some parts of the 18th-century baroque building are open to the public, this is not the reason why the majority of people visit the island. Most people come to admire the island’s stunning natural and horticultural scenery.

Flower island Mainau

The park-like arboretum has around 500 varieties of deciduous and coniferous trees, some of them more than 150 years old. In addition to Atlas cedars, Lebanon cedars and imposing tulip trees, the island’s collection also includes one of the oldest giant sequoias in Germany. It can be found to the north-west of the castle.  If you love tropical and Mediterranean plants, head for the Palm House. Here you will find more than 20 different types of palm, including a 15-metre-high Canary Island date palm that was originally planted on Mainau in 1888. An equally exotic experience awaits visitors to the Butterfly House and there’s always a chance that one of the colourful butterflies from Africa, Asia, Central and South America will actually land right on the end of your nose!

Mainau open all year round

The flower island is a wonderful place to visit at any time of year. In spring there is a spectacular display of over 3,000 orchids in the Palm House and the unforgettable “sea” created by 400 tulip varieties in the gardens.  In summer, the flowers in the Italian Rose Garden are in full bloom, while 12,000 dahlias produce a veritable firework display of colours and shapes from the end of August onwards.
There is always something to see, so the island (which belongs to Konstanz) is open to visitors 365 days a year, from dawn to dusk. You can get to Mainau by public transport (bus, boat) or by bike or car (parking available on the mainland).
