It’s not for nothing that Fehmarn is known as the ‘Sun Island’. It’s one of the sunniest regions in Germany, and yet every holidaymaker is bound to experience a grey day sooner or later. The good news is that a rainy day here isn’t a wasted day.
On this page you’ll find the island’s indoor attractions, sorted by what really matters on a rainy day: are they even open? After all, some of the attractions operate seasonally, and that’s exactly what most ‘must-visit’ lists fail to mention. We checked their opening times in August 2026. All distances are given from Burg on Fehmarn.
In summer, you’ve got plenty of choice on Fehmarn. In winter, it’s a different story: several of the best-known attractions are closed then, as they’re geared towards the holiday season. Anyone visiting in November or February should take this into account, rather than relying on a list compiled in July.
That is why this page states for each destination whether it is open all year round. We have deliberately chosen not to list specific opening times and admission prices, as these change regularly. Please check these directly with the relevant provider before you set off.
And there’s one more thing to bear in mind: on Fehmarn, a shower is rarely a long-lasting phenomenon. The weather changes quickly here, and what looks like a wasted day in the morning may well have cleared up by the afternoon. It’s therefore worth not scrapping your whole itinerary straight away, but instead choosing a destination for a few hours.
The Marine Centre in Burg is the island’s most reliable attraction. An underwater tunnel leads through a large tank, and there are also sand tiger sharks, lemon sharks and nurse sharks. It is open all year round, although opening hours are restricted in winter and it is partially closed over the festive period. Further details can be found on our page about the Fehmarn Marine Center.
The FehMare Water Park on the Südstrand promenade in Burgtiefe combines a seawater wave pool with a spacious sauna and wellness area. A rainy day spent in the warmth, whilst the wind sweeps across the beach outside, certainly has its charm. Please note: in winter, the pool is closed for several weeks for maintenance. With the Ostseecard, you’ll get a discount on admission. You can find out what other wellness facilities are available on our website at Wellness on Fehmarn and to the Sauna.
There are cinemas on the island too: the Burg Filmtheater on Breite Straße in Burg shows the latest films in a 1970s-style cinema. It’s often the easiest option for a rainy afternoon with teenagers.
The Vitarium in Burgtiefe is a 3,000-square-metre glass-roofed conservatory that connects the panoramic viewing pavilions of the IFA Fehmarn Hotel. Set amongst palm trees and fountains, it features an indoor playground, a game of pit-pat, restaurants and shops. As access depends on the hotel’s opening hours, it’s worth checking the current times in advance. Find out more on our page about the Vitarium Fehmarn.
The Galileo Knowledge World at the entrance to Burg is the region’s largest hands-on museum and is divided into a BioWorld and a TechWorld. It operates seasonally and is mostly closed in winter.
The Butterfly Park in Burg features free-flying butterflies in a warm, tropical hall. It is open from around April until well into November. On a cool, wet day in particular, the warmth there is a draw in its own right.
The FUNtasia Adventure Mini Golf at Burgstaaken Marina is housed in a large boathouse and features 22 holes. It operates during the summer months only, so it is not a year-round alternative for rainy days. You can find out where else you can play on our website Golf and Mini-Golf on Fehmarn.
The Submarine Museum in Burgstaaken harbour, which features the walk-in U11, also operates on a seasonal basis and is closed in the depths of winter. Experience has shown that the published opening times are not always up to date, so it’s worth giving them a ring before you set off. Right next door is the Sea Rescue Museum, which tells the story of sea rescue and displays a rescue cruiser. Together, they’ll keep you busy for an afternoon. More on Submarine Museum.

Farmworld Fehmarn, the miniature world of agriculture, continues to feature in many recommendations for things to do on the island when the weather is bad. It is permanently closed. Its own website states it quite clearly: on 19 April 2026, after twelve years, the operators closed their doors for good because the lease had expired and no new premises could be found.
We’re mentioning this here because a wasted journey on a rainy day is doubly frustrating. So if you come across a list that still includes Farmworld, it’s not up to date.
Fehmarn has more museums than the island might suggest at first glance. There are six venues, ranging from the Fehmarn Museum – housed in a pastor’s widow’s house dating from 1581 – through maritime technology to Schleswig-Holstein’s oldest working windmill. The history of German windsurfing is also chronicled here.
Opening times vary considerably from one venue to another, and several close for the winter. You can find out which six these are and what they are exhibiting in our guide to the Museums on Fehmarn.
Visiting a museum on a rainy day has one underrated advantage: the buildings are small enough that even impatient companions won’t feel overwhelmed. Visiting two of them in one afternoon works well, as they are close to one another in Burg and the surrounding area.
Anyone interested in art will also find traces of Ernst Ludwig Kirchner on Fehmarn. The painter spent several summers on the island and created part of his body of work here. You can find out which of these works are on display today on our website at Ernst Ludwig Kirchner on Fehmarn.
Not every rainy day has to cost you money. A stroll through the island’s capital, Burg, is still enjoyable even when it’s drizzling, as the shops on Breite Straße and around the market square are all close together. Find out more on our page about the Shopping on Fehmarn.
The churches on the island are well worth a visit even for those with no connection to the church, as they are among the oldest buildings on Fehmarn. Our page on the Churches on Fehmarn.
Here’s a tip that hardly anyone is aware of: with the Ostseecard, you can borrow items from the municipal library free of charge, and there’s free Wi-Fi at several hotspots across the island. The daily newspapers in the foyer of the tourist information centre are also available free of charge.
And finally, there are the farm cafés and farm shops. A long breakfast in the rain is almost nicer than one in the sunshine, and the farm shops are also the best chance to take a little something from the island home with you. You can find out where to stop off on our page at Dining on Fehmarn.
Between November and March, the choice becomes considerably more limited, and that is the most honest piece of advice this website can offer. The Butterfly Park, Galileo Knowledge World, indoor mini-golf course and submarine are usually closed during this period. Even so, there is still more to do than you might expect.
The Marine Centre is also open in winter, albeit on fewer days. The Burg Filmtheater continues to screen films, the shops in Burg are open, and the FehMare water park is the warmest place on the island outside its annual maintenance weeks. Then there are the courtyard cafés, which have a completely different, quieter atmosphere in winter than they do in August.
If there really is nothing to do on the island, the mainland is close by. Weissenhäuser Strand, with its subtropical water park, is about half an hour away and can be enjoyed whatever the weather. Further destinations in the area can be found on our page about the Day trips from Fehmarn.
With children, the order is usually clear: first the Marine Centre, then the water park, and once you’ve done both, the indoor play area at the Vitarium. During the season, the Butterfly Park, Galileo World of Knowledge and the mini-golf hall are added to the list.
You can find out what else makes the island a great destination for families – from the lifeguard-patrolled beaches to the cycle routes with no hills – on our website at Fehmarn with Kids.
Not everything that’s beautiful on the island works in bad weather. The cliffs in the east become slippery when wet, and the view that draws visitors there disappears into the grey. Birdwatching in Wallnau also depends on good visibility and tranquillity – neither of which is guaranteed in a storm.
The same applies to cycle rides: there’s nowhere to take shelter on the open dyke, and when it rains, the wind comes from the side. If you still want to go out, it’s better to plan a short ride through the island’s interior rather than a coastal route. And simply postpone the long ride until the next day, as the weather here often changes more quickly than the forecast suggests.
It’s on a grey day that you really see what a place to stay is made of. Enough space so you don’t trip over one another, and a location from which indoor attractions are just a few minutes’ walk away – that’s what makes the difference between a wasted day and a cosy one.
