About Mainau Island

Recommended Travel Resource: Lonely Planet Germany (Travel Guide)

Located in the Lake of Constance (Bodensee), the flower island of Mainau didn’t always have a flowery past.

The history of the island stems all the way back to 2000 years when it was originally used as a strategic fortress by the Romans. Eventually Mainau Island was inhabited by the Teutonic Knights after which it fell into the hands of the Swedes.

Yes, the island has a history that can be likened to that of fairytales!

Mainau was eventually sold to Grand Duke Friedrich I of Baden who transformed the island into a personal garden park for the castle he inhabited as a summer palace. This botanical paradise didn’t get its modern-day status until 1932 when his grandson, Count Lennart Bernadotte, modified the gardens to the flower wonderland it is today.

Best Time to Visit Mainau Island

Since Insel Mainau is in the temperate zone in Germany, the island experiences all four seasons. While each season on the island comes with its own share of attractions, the best time to visit Mainau Island is in Spring or Summer.

I mean, we’re all about that warm flowery vibe aren’t we? (Pretty sure we are!)

It’s the best way to optimize your vacation in Europe and also guarantees bang for your buck!

However, if you’re still curious to find out what Mainau Island offers in each season, here’s what you can expect.


Spring marks the true awakening of the flowers on Mainau Island. Beginning mid-March the island is covered in nature’s colourful beauties. A spectacular display of tulips, cherry blossoms, narcissi, daffodils, hyacinths, pansies, forget-me-nots, and primroses are sure to get you in the Spring mood. By mid-May running in to June you’ll be able to enjoy rhododendrons and azaleas.


Already in full flower swing, the transition from Spring to Summer brings along with it a change in floral displays. Unlike Spring whose main stars are the tulips, Summer exhibits a myriad of rose and dahlia species.

Mainau Island also becomes much busier in the summer time as it is filled with curious nature loving tourists. However, if crowds aren’t your thing you can, either go in the early morning or in the late evening to avoid the crowds.


Autumn is the last hurrah of the colourful spread as the dahlias carry the show into the winter season. The dahlia blossom is usually over when the temperature falls below the frost limit, which is typically in the second half of October.


Unfortunately, in Winter, there is no flower display. However, if you are still interested in a visit, you could still enjoy a walk around the park, explore the indoor palm garden or even explore the Mainau Castle.

The easiest and closest city to traverse from to get to Mainau Island is the city of Konstanz (Constance). From Konstanz you’ll find varying options to choose from.

If you’re travelling with a personal vehicle, you’ll need to follow the federal highway B 33 which leads you to the island. Once you’ve arrived and payed entry, you’ll take a short walk across a pedestrian bridge that leads you onto the stunningly beautiful flower island.


Another fantastic option is to travel by ferry to Mainau’s harbour (Mainau Hafen). Personally, I’d love this option since it gives me the true sense of arriving on an island!

Special Attractions at Insel Mainau

Even though I’m sure we’re all visiting Insel Mainau for its beautiful flowers, I’m here to also tell you that the flower island offers much more.

Mainau Castle (Schloss Mainau)

Open Daily: 10 am- 5pm

As if the island didn’t seem enough of a fairytale, let’s add a real-life castle to the mix. Yes, the Mainau Castle (Schloss Mainau) is an actual attraction on Mainau Island.

Fashioned in the Baroque style of architecture, this historical gem should be a key feature to visit on your trip. Explore the castle then take a quick snack break by its restaurant.

Butterfly House (Mainau Schmetterlingshaus)

Open Daily (Summer Season): 10 am- 7 pm

Adding also to the whimsical feeling of the island is the Butterfly House (Mainau Schmetterlingshaus). Immerse yourself among the millions of free flying butterflies in this gorgeous tropical sanctuary. How many times can you say you’ve done that?

Italian Floral and Water Cascade

Particularly impressive for me was the Italian floral and water cascade. This stepped water feature seemed like one straight out of a royal garden in the 18th century.

Palm House

Open Daily: (Summer) 9 am- 9 pm, (Winter) 9 am- 5 pm

Another tropical feature you’re sure to like is the Palm House. Explore the various species of palms as well as the special showcase of orchids (seen only in Spring and Summer).
