Startseite / Diemelsee

The nature and holiday region of the Diemelsee lies on the edge of the beautiful Sauerland. Not only nature lovers and hikers, but also water and active sports enthusiasts and above all families get their money’s worth here.
The Sauerland is not without reason one of the most popular holiday regions in Germany. Attractive leisure activities and offers await you all year round. In our blog we will regularly show you why it is worth visiting Diemelsee and Holiday HOUSE Marta. This gives you as our guest the opportunity to plan excursions even before your holiday and to enjoy the anticipation of your holiday.

With great attention to detail, Holiday HOUSE Marta invites you to a dream holiday:


At the Holiday HOUSE Marta you will find everything you need to make your family happy during the holidays. The baby equipment includes a baby bed, a high chair and a toilet seat.
Our selection of games has the right material for every age. In the morning everyone is motivated to walk to the lake, but in the evening the children’s legs are too tired to walk uphill? Our handcart is at your disposal free of charge.
For first hikes with your children you will find the Estenberg right next to the park with an adventure circular trail for children.
In summer, of course, the Diemelsee beach, only 200 metres away, invites you to swim and splash around. There you will find a big water slide, playground equipment, lots of sand and a snack bar with WC. Further playgrounds are located at the lidos along the Diemelsee shore and directly in Heringhausen next to the golf park.
There is no boredom even in winter: Go on a winter hike, snowball fight or sleigh ride with your offspring right outside the door. Afterwards you can bake fresh waffles with the whole family in Holiday HOUSE Marta. Or how about a sled dog adventure tour?
The easily accessible neighbouring town of Willingen is also always ideal for an excursion: whether it’s the summer toboggan run, the famous ski jump or the game park – there’s something for every taste and every weather condition.

Active holidaymakers and winter sports enthusiasts…

The forests and mountains of the Sauerland are ideal for mountain bikers and racing cyclists. The mountain bike stronghold of Willingen is only 14 km away. At the Holiday HOUSE Marta we have maps with the most beautiful routes ready for you. Also those who want to enjoy the picturesque scenery by bike or e-bike will find pleasure bike tours around the Diemelsee.
In winter the neighbouring town of Willingen offers ideal conditions for skiing and tobogganing, at weekends also with floodlight and après-ski. For those who like it a little quieter, there are two cross-country ski runs in Schweinsbühl, 8 km away, with optimal conditions and a breathtaking view.
Riders also get their money’s worth at Diemelsee.

Nature lovers and people seeking relaxation…

On your arrival you will feel it: Already on the last few kilometres you will leave everyday stress behind and the holiday can begin.

In the surroundings you will find great cafés and restaurants for pleasurable hours. Enjoy the fresh, regional cuisine and let us spoil you with culinary delights.

Peace of mind

The people from the Sauerland have set out and chosen their soul places. These are places that are particularly impressive and important – places of the soul. There, guests and locals alike can experience the silence, distance from everyday life, solidarity and home. Around the Diemelsee there are 5 such soul places, which we will introduce bit by bit. If you want to get to know them beforehand, take a look here:

If you enjoy being out in the fresh air and love the varied and unique nature, a hiking holiday on Lake Diemelsee is just the thing for you! Enjoying the fresh green in spring or the colourful flower fields in summer, running away from the autumn blues on a hike through the colourful forests or walking through the silence of a snow-covered winter landscape – hiking is a trend for young and old. When you return in the evening from the wonderful nature, you can enjoy the peace and quiet in HolidayHOUSE Marta.

“And then you still have to have time to just sit there and look ahead” (Astrid Lindgren).

Sit on the balcony with a bottle of wine and enjoy the great view of the Diemelsee and the mountains. Or let your soul dangle during a comfortable wellness day in the sauna of HolidayHOUSE Marta.

Water sports and fishing

The excellent water quality attracts swimmers, surfers, fishermen, sailors, canoeists and divers to the Diemelsee.
Idyllic bays, a water depth of up to 34 m but also shallow banks offer the anglers among you a picturesque and varied scenery. The lake Diemelsee is also divided into two arms: just behind the dam the lake divides into the Itterarm and the Diemelarm.
Thanks to the boat rental you can be your own captain and explore the Diemelsee comfortably by electric boat or sporty by pedal boat or rowing boat. Furthermore, the MS Muffert regularly invites you to take a tour of the lake, offers food and drink on board or a ferry boat tour with a combination of hiking and boat trips.
The Diemelsee is the focus of activities in summer: swimming, paddling, surfing and paddling. Or how about the trend sport of summer 2020: Stand up Paddling (SUP)?

Stand Up Paddling at the Diemelsee

Since summer 2020 at the latest, there is a new trend sport: Stand Up Paddling (SUP). Originally from Hawaii, standing paddling, which has been translated into German, has now developed into a worldwide leisure sport. Great that it is also possible to book courses or rent the complete equipment at Diemelsee. Of course we don’t want to miss that. […]

Ball track at the summer toboggan run in Willingen

The summer toboggan run in Willingen is also known far beyond the borders of the Sauerland. Since the summer of 2019, there is a great addition right next door: on a 60 m long wooden marble run, even the smallest children can race with the balls. It’s great fun that provides plenty of exercise and is also easy on the […]

The Dommel tower

A day in January. The air is freezing cold, it is still early. The sun makes its way through the fog and suggests that a great day lies ahead.
What can you do in the Diemelsee holiday region today? We immediately have an idea: let’s go to the Dommel. 738 m high and at the top the Dommel tower rises […]

The Estenberg: really hikable for children

The Estenberg right next to the Holiday HOUSE Marta is a great place to go on a discovery tour with little hikers. We have tested him. Most children do not like to walk long distances – unless they have an interesting destination in mind. This is exactly what the Estenberg offers, because here you can follow the squirrel trail […]
