Sonnenalp Resort

The hotel has been managed by the same family since 1919 - today Anna-Maria & Michael Fäßler are constantly working on the concept of a modern resort with a traditional character. More and more the focal points are crystallizing, which make the hotel the incomparable address in the alpine region: Wellness, culinary delights, golf and winter sports, combined with a wide range of amenities for families. Sonnenalp has been completely renovated in recent years and now shines in new splendour for its 100th birthday in 2019. The traditional 5-star luxury resort Sonnenalp in the Allgäu Alps is a year-round destination for connoisseurs, active people, wellness holidaymakers and golfers. Whether through the creative culinary art in various restaurants or the sun-drenched winter sports on world class level at the Ofterschwanger Horn - here every guest experiences his individual moment of well-being. Externally renovated and internally completely renovated, the entire resort awaits you with a harmonious combination of alpine and traditional elements as well as modern elegance crowned by loving details.

First-class feel-good factor

The rooms have been re-styled with natural materials such as wood and stone, creating unique moments of surprise. A symbiosis of colours and elements specially adapted to each room type gives each room its own unique charm. The outdoor wellness area was extended in 2018 with natural lakes, numerous sun decks, pools and a natural playground. A further highlight in the newly created wellness park is the nature spa for adults with log cabin and panorama sauna, large outdoor whirlpool and relaxation area with a picturesque view of the Ofterschwanger mountains. The holistic indoor spa programme ranges from soothing body and cosmetic treatments to activating fitness courses and medical wellness services. Also impressive is the colourful activity programme with up to 35 points from sport, culture and entertainment every week. Sonnenalp also offers Germany's largest hotel ski school in winter, three golf courses, its own Tennis Academy, a riding school and the rental of mountain bikes, e-bikes, trekking bikes and children's bikes of the best brands in summer. In addition, the award-winning children's and youth programme includes over 70 age-appropriate and adventurous activities, making the holiday unforgettable for the whole family.
