Hotel Sonnengut: greetings from the front desk
The Hotel Sonnengut lies on the Aunhamer Berg in Bad Birnbach — in the region travel guides list as the “Lower Bavarian Tuscany”, because hills, hours of sunshine and a vineyard-like feel come together. The Franzke family runs the four-star-superior house with its own thermal bath, fed with Bad Birnbach healing water straight from the spring, an extensive sauna landscape and a medical-wellness area. Four culinary addresses under one roof (Sonnengut Restaurant, Hirschstube, Arthur's 1994 Bar, Sonnengut Terrasse) and an activity programme that ties in the Rottal yoga trails and several golf courses.
Spa, thermal bath and sauna landscape
The spa area spans 3,000 m². At the centre stands the in-house thermal bath with Bad Birnbach healing water, complemented by a brine pool and a freshwater pool. The sauna landscape is broad, plus a rest area that takes the spa seriously as a place to spend the day. Beauty and medical-wellness treatments — up to CoolSculpting-like procedures — are set up as a line of their own.
Four culinary addresses
The Sonnengut Restaurant as the main address, the Hirschstube for the more upmarket programme, Arthur's 1994 Bar as the day and evening bar and the Sonnengut Terrasse for the warm season. Concept: sustainable regional cuisine with seasonal events (wine parties, Italian and Spanish evenings, truffle menus).
Rooms and suites
From single and comfort double rooms (~30 m²) via wooden-floor double and comfort gallery rooms (~40 m²) to suites (56–100 m²), plus family rooms for guests with children. Design concept: light, modern Bavarian, plenty of wood.
Rottal yoga trails, golf and an activity programme
Four specially signposted “Rottal yoga trails” lead through the Lower Bavarian natural backdrop — a mixture of guided movement and nature experience. Add several golf courses within immediate reach, cycle paths, hiking trails and Nordic-walking routes.
Klimapakt Bayern and e-mobility
The Sonnengut is a Klimapakt Bayern partner — an initiative of the Bavarian hotel trade to reduce CO₂ and resource consumption. E-charging points for guests' vehicles are standard; sustainable regional cuisine and energy management are systematically integrated.
Bad Birnbach and the Lower Bavarian Tuscany
Bad Birnbach lies in the Lower Bavarian Rottal — between Passau and Bad Griesbach, part of the spa triangle of Bad Füssing, Bad Birnbach and Bad Griesbach. The hilly landscape with above-average sunshine carries the nickname “Lower Bavarian Tuscany”. In-house thermal baths, golf courses and cycle and hiking paths are within walking distance or a short journey.

Frequently asked questions about the hotel
What does the 3,000 m² spa area comprise?
At the centre stands the in-house thermal bath with Bad Birnbach healing water, complemented by a brine pool and a freshwater pool. The sauna landscape is broad, and the rest area takes the spa seriously as a place to spend the day.
Alongside runs a beauty and medical-wellness line of its own — from classic massages and facial treatments to equipment-based procedures.
What is special about the thermal water in the house?
The thermal bath is fed directly from the house's own spring — Bad Birnbach healing water, which has established the town as a spa since the 1970s. Whoever stays at the Sonnengut bathes in healing water without leaving the house; it is used both in the therapy context and in the classic spa programme.
“Lower Bavarian Tuscany” — why this nickname?
The Rottal around Bad Birnbach, Bad Füssing and Bad Griesbach carries the nickname “Lower Bavarian Tuscany” — because of its gentle hill landscape, a duration of sunshine above average for Bavaria and a travel tradition that combines the spa triangle with culinary and scenic pleasures.
What are the Rottal yoga trails?
Four specially signposted trails through the Lower Bavarian hill landscape that combine guided movement with nature experience — the Sonnengut ties them into its activity programme. Add several golf courses within immediate reach as well as cycle, hiking and Nordic-walking routes.
Where do you eat at the Sonnengut?
At four addresses under one roof: the Sonnengut Restaurant as the main address, the Hirschstube for the more upmarket programme, Arthur's 1994 Bar for day and evening and the Sonnengut Terrasse in the warm season.
The line is sustainable regional cuisine, given rhythm by seasonal events — wine parties, Italian and Spanish evenings, truffle menus.
How sustainable is the Sonnengut?
The house is a partner of Klimapakt Bayern — the initiative of the Bavarian hotel trade to reduce CO₂ and resource consumption. E-charging points for guests' vehicles are standard, and energy management and sustainable regional cuisine are systematically integrated.
