Baltic Sea holiday home with sauna - Nature, relaxation & comfort

A special holiday home on the Baltic Sea - with sauna, design and an exceptional location in the middle of Schleswig-Holstein's nature.

A holiday home on the Baltic Sea - rethought

Are you dreaming of a Baltic Sea holiday in a holiday home with a sauna?
A high-quality alternative to the classic holiday home awaits you at the Baltic Sea tree house hotel: fully equipped, architecturally designed tree houses, quietly located and deliberately reduced - high above the treetops.

Generous glass fronts, clear lines and well thought-out room concepts create a feeling of space and tranquillity. Instead of dense holiday home settlements, here you will find distance, nature and time for yourself.
Our exclusive wellness area with sauna and whirlpool offers relaxation in the midst of nature - quietly embedded, without the hustle and bustle, deliberately designed as a retreat.

Why a tree house instead of a classic Baltic Sea holiday home?

Exceptional location
Spend the night at treetop level - surrounded by meadows, ponds and old trees.

Exclusive wellness area
Sauna and whirlpool surrounded by greenery - as an offer for relaxation, not as a compulsory programme.

Peace & distance
Extensive natural area, deliberately reduced structure and no dense development.

Year-round comfort
High-quality construction, heating and air conditioning - cosy all year round.

Sustainable architecture
Durable materials, clear design and respectful treatment of the landscape.

Pleasure & lightness
Breakfast basket in the tree house or culinary offerings on site - uncomplicated, quiet, conscious.

A holiday home experience for every season

Summer: beach days, bike tours and balmy evenings on your own terrace.
Autumn: Clear air, peaceful nature and soothing warmth after long walks.
Winter: Retreat, tranquillity and relaxing wellness moments with a view of the countryside.
Spring: A blossoming landscape, light and new energy - ideal for conscious time-outs.

Baltic Sea holidays with wellness & nature

In addition to walks, coastal excursions and nature experiences, our Baumhaus SPA offers additional opportunities for relaxation.
Selected, dog-friendly tree houses are available for guests with dogs; there is also deliberately pet-free accommodation for allergy sufferers.

The Baltic Sea, Fehmarn, Heiligenhafen and the region's nature reserves are within easy reach - and yet you return to a place of peace and quiet in the evening.

Your overnight stay in nature - The tree house hotel

The Ostsee Baumhaushotel is the only tree house hotel of its kind in Schleswig-Holstein - and a real insider tip for anyone who loves nature, design and relaxation and would like to spend the night in a tree house.
Situated between rolling hills, old fruit trees and a small, rustic alder forest, our tree houses offer a stylish break high up in the treetops. With sophisticated Scandinavian design, sustainable construction, air conditioning, high-speed WiFi and a private terrace, each tree house combines modern amenities with the feeling of freedom and security in nature.

You won't find mass accommodation here, but a retreat for special moments - whether as a romantic couple, a short break alone or an oasis of inspiration for creative minds.

Your breakfast awaits you in a picnic basket, the starry sky flickers over the natural pond, and if you like, you can enjoy our wellness area with sauna and hot tub in the middle of the countryside. Welcome to the first tree house hotel on the Baltic Sea - one with nature, sustainable with a vision.
