The Baumhaus am Kellerberg sits in the village of Siegertshofen, tucked inside the Augsburg-Westliche Wälder Nature Park near Fischach. From the moment you step off the meadow path and into the trees, the scale of things shifts. The noise of ordinary life drops away. What replaces it is birdsong, moving leaves, and a quietly remarkable treehouse waiting among beech and spruce.

Inside, the design keeps faith with the forest outside. Pale timber floors, honeyed walls, and wide windows bring in light and green in equal measure. A comfortable double bed anchors the main living space. A wooden ladder leads up to a loft that delights children and quietly tempts most adults too. The whole space suits up to four guests, though two will feel especially at home here.

The kitchenette is honest about what it is: stove, fridge and solid cookware for simple meals between walks. That is all you need. The bathroom is modern and reliably comfortable, keeping "rustic" firmly in the realm of aesthetics rather than experience. A cosy seating nook rounds out the interior — the right place for a slow afternoon with a book or a long evening of conversation and games.

The balcony is the heart of the place. Elevated, spacious and aimed directly at the treetops, it earns its keep from the first morning coffee to the last glass of wine at dusk. Birds announce themselves at dawn. Leaves shift and settle through the afternoon. The light changes slowly and generously. Few spaces this simple feel this rewarding.

Down at ground level, a dairy goat farm sits next door and gives the stay its agritourism warmth. Children can meet the animals and sometimes help at feeding time. The hosts are genuinely knowledgeable about the land around them and share that knowledge lightly and well. Spring and early summer bring the most vivid conditions: mild air, strong birdsong, and trails at their best. Autumn offers a quieter, more atmospheric mood — golden light, cooler evenings, and noticeably fewer visitors.

The nature park unspools in every direction with walking and hiking routes that reward both gentle strollers and more ambitious hikers. Augsburg sits close enough for a day trip and offers a full change of register: the cathedral's cool interior, the Fuggerei — widely cited as the world's oldest surviving social housing complex — and the beloved Augsburger Puppenkiste puppet theatre. Nightly rates run approximately €200–€300, varying by season and availability, which places this firmly in moderate territory for a private treehouse with this level of character and setting.

For guests travelling without a car, the Siegertshofen bus stop lies approximately 250 metres from the property and serves bus lines 604, 606, 607, 694 and 707. Langenneufnach train station sits approximately 3 km away and provides a rail connection into the wider regional network. Fischach station offers an alternative at approximately 4 km. That said, most visitors arrive by car given the rural setting, and the address is straightforward to reach from the regional road network around Augsburg.

Baumhaus am Kellerberg suits anyone who wants genuine natural immersion without sacrificing comfort. It works equally well for couples wanting unhurried days and real quiet, and for small families looking for something more memorable than a hotel room. Augsburg is close enough to fill a day with culture. The forest is close enough to fill the rest of the time with everything that actually matters.
