In the middle of Holbæk, just a short distance from the rhythm of the city, lies a green oasis where the world feels like it has quietly come to a standstill. Holbæks Grønne Lunge – Holbæk's Green Lung – is a 45-hectare nature and outdoor recreation area that offers shelter stays for anyone who wants to sleep under the open sky without travelling far. Here, nature is not simply a backdrop: it is the entire point.

The shelters are situated within the animal park area, surrounded by woodland, meadows and abundant wildlife. Fallow deer, sika deer, wild geese and wild boar make their home here, and an early morning walk through the park at first light is the kind of experience that sets the tone for the whole day. The area has been developed as Denmark's first biodiversity zoo, created with the ambition of letting nature set its own terms, rather than staging it for human convenience.

For overnight guests, there are fire pits and natural surroundings that make it easy to step away from screens and everyday noise. Wake to birdsong in the tree canopy, head out along one of the marked trails and discover how Holbæk's green heart beats both quietly and vibrantly. An equipment library offers gear for hire, making it simple to explore the area on foot, by bike or by canoe – whether you are a seasoned outdoor enthusiast or completely new to the experience.

The area forms part of Destination Sjælland and Holbæk Municipality's commitment to sustainable outdoor recreation. From here, you have easy access to the town of Holbæk, the fjord and the wider West Zealand landscape – making it the ideal base for a nature-filled weekend close to everything and yet far from the everyday.

As Denmark's first biodiversity zoo, Holbæk's Green Lung takes a distinctive approach: rather than exotic animals behind fences, native wildlife roams freely in its natural habitat. Fallow deer, sika deer, wild geese and wild boar share the grounds with visitors, and early risers may encounter the animals during their morning routines.

Experiences in and around Holbæk

Holbæk's Green Lung lies within walking distance of the town centre and the fjord harbour, making it easy to combine a shelter night with a trip into town. Holbæk Fjord offers swimming, kayaking and sailing, and the old harbour has cafés and restaurants overlooking the water. For history enthusiasts, Holbæk Museum tells the story of the town's medieval roots and the cultural heritage of the surrounding landscape. Nature trails connect the Green Lung with Holbæk Plantage and onward into the open countryside towards Tuse Næs, where the quiet coves of Isefjord and small villages create a feeling of island idyll on the mainland. Cycling routes run along the fjord and through rolling terrain to the Orø ferry or northward towards Lammefjorden, where Denmark's flattest landscape meets the horizon.
