Germany's "Flower Island" in Lake Constance

Mainau, nicknamed "The Flower Island," is the most popular tourist attraction on Lake Constance (a.k.a. the Bodensee).

The small island, which is about 5 km or 3 miles from the city of Konstanz, has a semitropical climate that inspired Prince Nikolaus von Esterházy to create a botanical garden in the first half of the 19th Century.

Later, under Grand Duke Friedrich I, the gardens were expanded with an arboretum, an Italian rose garden, and other features that visitors enjoy today.

In the 1930, Prince Wilhelm (then the island's owner) turned the administration of Mainau over to his son, the Swedish Prince Lennart Bernadotte II. The prince, who had renounced his Swedish royal lineage after marrying a commoner, devoted the rest of his life to turning the island into a privately-operated park.

Mainau is now maintained in perpetuity by a foundation that the prince and his second wife established, and the island's manager is their daughter, Countess Bettina Bernadotte. Their son, Count Björn Bernadotte, manages the foundation.

What to see and do

Mainau's 45 hectares or 111 acres of gardens and landscaped grounds attract more than a million visitors each year.

The flower season begins in spring with an orchid show in the Palm House and a million tulips that bloom from March until May. Rhododendrons follow the tulips, and in summer another 350,000 flowers are on display. Dahlias bloom in September, pleasing visitors until the gardens wrap up their season in late October.

(Other attractions include a rose garden and exotic plants such as banana and palm trees, bougainvillea, and fuchsias.)

In addition to flower gardens, Mainau has an arboretum, a butterfly house, a gallery with special exhibitions, an area for children, a castle, a baroque chapel, and a variety of restaurants.

Allow a minimum of several hours for a visit, and plan on spending the entire day on Mainau if you're seriously interested in gardens.

Shopping in Mainau, Germany

After buying tickets to the private island of Mainau and its gardens, visitors pass through an outdoor shopping area with souvenirs, crafts, and food stands.

This area is near the boat pier. Mainau has another entrance just before the short causeway that leads from the mainland parking lot to the island, which you'll use if you're arriving by bus or car.
