This tiny island on the waters of Lake Constance hides numerous delights, including a Baroque castle, beautiful gardens and exotic wildlife.

Mainau Island, nicknamed the “Island of Flowers,” is just over 110 acres (45 hectares) in size and yet it offers enough in its compact borders for hours of entertainment. The small, wooded island on Lake Constance is not only a beautiful location, but it also contains a castle, gardens and glasshouses where multitudes of tropical plants grow.

Follow in the footsteps of the Teutonic Order of Knights, the first occupiers of the island who lived here in the 13th century. They built a castle on the island, which later became the palace that still stands here today.

Make the palace your first stop on your trip to the island. Admire the Baroque stylings of the castle, which dates back in its current form to 1746. Explore the other buildings on the island, such as the Gatehouse and the Castle Church of St. Mary.

Wander the formal gardens surrounding the castle. Thousands of flower species line the water features and paths. Don’t miss the Rose Garden, which was created in 1871 for the Duke of Baden.

Travel to the tropics in the Palm House. This ornate glasshouse creates a climate suitable for growing over 20 different kinds of palm tree. Marvel at the fragile beauty of the orchid collection that also grows here.

Surround yourself with butterflies in the Schmetterlingshaus. Around 1,000 of the delicate creatures live in the house. Children will also enjoy visiting the farm animals in the Bauernhof, where you can ride ponies and meet rare livestock breeds.

When walking around the island, look for the Viktoria lime and the knotted pagoda trees, both of which are about 150 years old. Wander along flower-lined terraces that look out across the lake.

Mainau Island is north of the city of Constance. Ride passenger ferries from the city to reach the island and its attractions, which are open daily from sunrise to sunset. Adult visitors will have to pay a fee, while children under 12 get in for free.

9.2/10 Wonderful! (142 reviews)
A basic, no-frills hotel offering the essentials without extras like a mini fridge or coffee/tea-making facilities. The bed was a little on the hard side, but the room was clean and functional. The real highlight is the location—within easy walking distance to the charming old town, making it a convenient base for exploring the area.

Quaint new hotel, very helpful staff. Rooms small and somewhat cramped but with a beautiful view of the mountains. Still working out the kinks of a new property including renovations/beautification of landscaping and pool which was very loud from 7am-10pm every night.
