Adults-only hotel on the Baltic Sea - Your retreat in nature

As an adults-only hotel, our tree house hotel is deliberately aimed at those seeking peace and quiet who want to enjoy nature, privacy and time for themselves.

Our unique tree house lofts and tree house lodges float five metres above the ground and give you a sublime view of the greenery.

Who is the tree house hotel suitable for?

For couples, single travellers and small families looking for peace, nature and special architecture - and who can consciously do without traditional children's facilities. At the Baltic Sea tree house hotel, the focus is not on the classic family programme, but on peace, nature and a conscious experience. Small families with children are welcome here if they appreciate this reduced form of holiday. However, our hotel is not geared towards children or toddlers.

Why our adults-only hotel is the perfect choice for your holiday:

Pure peace & nature - No hustle and bustle, just the gentle sound of the trees.
High-quality tree houses - Scandinavian design, large panoramic windows & modern furnishings.
Relaxation & wellness - Our Baumhaus SPA with sauna & whirlpool for adults only.
Culinary delights - breakfast baskets & fine snacks in the Baumhaus Bistro (from 2026).
Privacy & exclusivity - your own tree house with terrace for undisturbed moments.
Dog or allergy sufferer? - Choose between pet-friendly or pet-free treehouses.

Adult preffered means for us at the treehouse hotel: We do not have any offers that are specifically aimed at children.
Our concept is deliberately aimed at those seeking peace and quiet who want to enjoy a relaxing holiday in nature.

Sleep at the height of the treetops - Our Baltic Sea tree houses & tiny houses

High up, at treetop level, you will find a new temporary home. Our tree houses are more than just accommodation - they are quiet observers of the forest, warm retreats with views into the distance and places full of peace and magic.
Scandinavian in design, cosy at heart - here you sleep above things and wake up to the sounds of nature.

Built with high-quality materials, sustainably designed and lovingly furnished, our tree house lofts & lodges invite you to simply let go.

Even the first night in a treehouse feels special - but it takes time to really arrive.

That's why a stay of two nights or more is deliberately part of our concept. We don't offer a quick overnight stay, but a real time-out in nature - at treetop level.

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.
