Hotel with outdoor pool
The DIEDRICH Wellnesshotel & Spa in the Hochsauerland region is a hotel with an outdoor pool. Heated and offering picturesque views, the swimming pool is designed as an infinity pool where you can spend many hours of the day enjoying the view of the valley and the long hours of sunshine.


Why we have an outdoor pool
For many people, water is simply part of their vacation, both in the warm and cold months—and we personally feel the same way. It's so wonderful to listen to the splashing of the water while relaxing in the open air in the sun, to watch the sun reflecting in the cool water, or to refresh yourself in the water after sunbathing. No wonder that many people see the pool as the heart of a wellness hotel, especially in summer. It's a great place to enjoy yourself when the temperatures rise.
Look out over the edge of the infinity pool and relax
The 20-meter x 5-meter infinity pool extends four meters beyond the existing hotel building, offering a unique swimming experience. From the edge of the infinity pool, you can look out over the Hallenberg Valley and enjoy the rising sun – pure romance. Around the pool, you will find a cozy spot where you can relax and enjoy the beautiful weather in the Hochsauerland region – both in the shade and in the sun.

Frequently asked questions about our hotel with outdoor pool in North Rhine-Westphalia
Is the infinity outdoor pool at DIEDRICH heated all year round?
Yes. Our outdoor infinity pool is open all year round and heated to a comfortable 31°C. So you can swim in the warm water while enjoying the view of the Hallenberg Valley—under blue skies in summer and with snow on the hills in winter.
Is the outdoor pool more suitable for swimming or just for relaxing?
Both. The outdoor pool measures 20 x 5 meters, allowing you to swim laps in a relaxed manner while still having enough space to simply float around. Many guests start their day with a few quiet strokes and then enjoy the gentle current with a view over the valley.
Who would particularly enjoy a stay at a hotel with an outdoor pool in the Sauerland region?
As an adults-only wellness hotel for guests aged 16 and over, DIEDRICH is aimed at couples, friends, and solo travelers who appreciate peace and quiet. If you are looking for a heated outdoor pool, saunas, relaxation rooms, and good food in a relaxed atmosphere—without the hustle and bustle of children and dogs—you will find the perfect retreat here in North Rhine-Westphalia.
Can I also use the outdoor pool as a day guest?
Yes, as part of our day spa offers, day guests can also use the wellness area with indoor and outdoor pools. As we deliberately limit the number of day spa places, it is important to book in advance so that the spa and outdoor pool area remain pleasantly quiet and you can really enjoy your time out.
How is the outdoor pool integrated into the overall spa area?
The infinity outdoor pool is directly connected to the indoor pool and spa areas. You can comfortably move between the indoor and outdoor areas, saunas, relaxation areas, and bathrobe bistro in your bathrobe without having to leave the building. This means that the outdoor pool feels like a natural part of your wellness break at any time of year.
Are there enough sun loungers and seats around the outdoor pool?
Yes, there are various loungers and comfortable seating options around the infinity pool and on the adjoining terrace. Depending on the time of day, you can find a spot in the sun or shade and enjoy the view of the Hochsauerland countryside—with plenty of space to breathe deeply.
Is the hotel with outdoor pool in a quiet location, or is it in a busy area?
Our hotel is located in Hallenberg in the Hochsauerland region, about 15 kilometers south of Winterberg. From the infinity pool, you can look out over a green valley with half-timbered towns and hills instead of a big city backdrop. This allows you to combine easy accessibility in North Rhine-Westphalia with genuine nature and a deliberately peaceful environment for your wellness vacation with an outdoor pool.

Wellness in every season
We want to be a wellness hotel where you can feel good – whatever the season. Our holistic approach to wellness is complemented by the outdoor pool and plenty of places to relax in the fresh air. We want to do justice to the four pillars of wellness – nutrition, exercise, relaxation, and social and emotional well-being – all year round, and have created wellness areas that invite you to explore and linger. The spa area therefore includes not only the heated infinity outdoor pool and the spa terrace, but also the sauna area, the spa bistro, the fitness area, the indoor pool, and much more. The goal behind this is to offer guests a wide range of relaxation options. Every guest is unique, and so are their needs for comprehensive relaxation.



As a wellness hotel with an outdoor pool, it is a summer destination.
We love what we do. Our hotel, our everyday life, our region. The Sauerland is particularly popular with many guests for wellness vacations in winter. Images of snow-covered landscapes quickly come to mind. Nothing fits better than a relaxing break in the warmth. Gaze out from the heated outdoor pool into the cool of winter, enjoy the pleasant heat in the sauna, or dine to the crackling sound of the fireplace. Yes, the Sauerland is almost perfect for a wellness vacation in winter.
However, what many people don't know is that it is also beautiful here during the warmer months.
Here in the Hochsauerland region, there are many lush green meadows where horses, sheep, and cows graze contentedly. There are gentle mountains that can sometimes be strenuous to climb, but which offer wonderful views of the Sauerland from many places. Hiking trails crisscross the landscape and give an impression of the diversity of the region. There are lakes all around, such as the Edertalsperre, the Hillebachsee, and the Weddelsee. Each has its own attractions—water sports, idyllic fishing, beaches, or picturesque shores. There are sights, monuments, and lively culture. Just think of the open-air stage, where the Passion of Christ is performed every ten years, the small ice museum, or the Kump with its interesting exhibitions in the city center. Despite all this, the Hochsauerland is still an insider tip for a relaxing wellness vacation in summer.


Summer vacation in the Hochsauerland region
The region alone offers enough reasons to visit the DIEDRICH Wellnesshotel & Spa during the warmer months. But there was always one thing missing in summer: water. And by that we mean an opportunity for you to enjoy the cool water in the fresh air on beautiful days while the sun pampers your skin. To watch the sun rise in the morning while floating in the water. To take a refreshing shower after a strenuous hike and then go for a gentle swim. Or simply to lie outside, relax, and consciously enjoy the moment. We want to fulfill this wish for our guests all year round with the heated pools at the wellness hotel.
Your wellness vacation at a hotel with heated indoor and outdoor pools
At DIEDRICH Wellnesshotel & Spa, the hotel focuses on wellness, so relaxing moments are the order of the day—exactly as you feel best. For this reason, our wellness hotel offers various places to retreat, cozy corners, and lots to discover.
The wellness area includes a light-flooded indoor pool, which is somewhat reminiscent of a Roman thermal bath and which we therefore affectionately refer to as the column bath. On two levels around the indoor pool, you can choose your favorite lounger and relax here while enjoying the view outside.

Hotel with heated outdoor pool and sauna area
Interplay between cold and heat
In addition to the swimming pool, the sauna area includes a Finnish panorama sauna with a large window, another Finnish sauna, a steam bath, a tecaldarium, a Swiss stone pine sauna also with a view of the outdoors, and our snow grotto, where you can cool off perfectly—ideal on hot days or after a sweaty sauna session. Here you can experience every temperature in a new way. There is also a large lounge area between sauna sessions and a relaxation area where you can enjoy the reflections of the water in the pool above through a round glass peephole. An incomparable feeling of space that has a calming effect with its gentleness. The heated outdoor pool is probably the most striking feature of our wellness area. Here you can relax and enjoy the moment on hot summer days. The pool is heated, so the water temperature of the infinity pool is always pleasant and invites you to swim in the heated water all year round.




Pamper your body – actively and passively
Interplay between movement and relaxation
Exercise—or at least the opportunity to exercise—is also part of a wellness vacation. Work out in our fitness room, take part in yoga or meditation classes in our Haus der Mitte, or enjoy the fitness facilities in the large fitness room. All course rooms are bright and have windows, so you can be motivated by the sun during your morning workout or enjoy the colorful twilight in the evening.
Of course, you can still pamper your body with a treatment. Whether it's a relaxing massage, a soothing facial treatment, or an Ayurvedic ritual, you'll find it easy to enjoy the moment and take a break from everyday life. In our treatments, we use natural cosmetics that are good for your body in the long term.
Enjoyment with all the senses
Cuisine is one of our strengths
Delicious food is also an essential part of your vacation in the Hochsauerland region. Take a seat in our restaurant, which is divided into different areas. Discover the "Alte Post," "Poststübchen," or "Antons" areas, all of which are decorated in earthy tones. We serve our half-board menu in the cozy Stammhaus Restaurant. Fine cuisine—and the desire to satisfy the culinary wishes of our guests—has always been a high priority for us. Whether with friends, buddies, or during a romantic dinner with your loved one, we do everything we can to make you feel completely at home.
