Mainau Island

Mainau Island, Germany

A paradise in Lake Constance

In addition to the sumptuous variety of flowers in bloom in the park and garden, every season promises its own special highlights, not only during the holidays. Unique attractions, even for cooler, rainy days, include the palm house and the butterfly house. Take a look at our rainy- day programme, for example exclusive palace tours are available if it is raining. The insect garden, the “Wasserwelt”, “Blumis Uferwelt” and “Zwergendorf” play areas and the treasure hunt offer children fun, variety and a true nature experience.


Bright colours and sweet scents
The most colourful of all seasons on Mainau is when the bulb flowers open. From March through May, you will discover a magnificent carpet of snowdrops, crocuses, daffodils, blue stars and tulips. From the end of May until the first frost, 12,000 rose plants adorn this Bodensee island, followed by dahlias in autumn. Imagine 12,000 sun-seeking tuber plants with 250 varieties and species along the island’s southern slopes in late summer and autumn.

Count's festivities
The highlights of the Mainau year include the annual Count's festivals. "Strolling, shopping, enjoying" is the motto at the Count's Island Festival and "Nobless Oblige" at the Count's Castle Festival.


Wander through and enjoy the wintry landscape of Mainau Island. Once you have explored the island, there are two attractions in particular you may want to visit: the Butterfly House and the Palm House. From 16 October 2020 to 7 February 2021, you can discover the winter exhibition „Remember your childhood as you rediscover the varied world of wooden toys“ at Mainau Palace. Also this year the palace court- yard is transformed into Scandinavian winter wonderland. 

Paradise for children 

Nature, fun and variety for children are guaranteed at Mainau with one of the largest butterfly houses in Germany, the newly opened insect garden, the playgrounds "Waterworld," "Blumis Shoreline,” and “Dwarf Village,” as well as the treasure hunt. Best of all: children up to 12 years are free of charge.
