Klækken Hotell Sauna

Historic hotel sauna with lakeside Flyt Fjord Sauna one hour from Oslo

Hønefoss, Eastern Norway

Klækken Hotell is one of Ringerike’s most established hotel properties, a 156-room retreat set at the edge of Nordmarka — the vast forest and lake landscape that stretches north of Oslo and defines so much of the Norwegian outdoor character. The hotel’s sauna and pool facilities make it a legitimate spa destination, and the addition of a lakeside Flyt Fjord Sauna takes the outdoor thermal experience to another level.

Located approximately one hour from Oslo by car, Klækken occupies a natural sweet spot between city accessibility and genuine countryside tranquillity. It is a popular destination for Oslo residents seeking a longer weekend escape without the need for a long drive.

Hotel Spa and Indoor Pools

The main spa area at Klækken centres on indoor and outdoor pools, a classic hotel sauna, and access to cold plunge facilities. The indoor pool allows year-round swimming regardless of weather, while the outdoor pool brings the natural surroundings directly into the bathing experience. The sauna is heated to traditional temperatures and is well-suited to longer sessions before or after pool use.

The Lakeside Flyt Fjord Sauna

The standout feature of the Klækken spa offering is the Flyt Fjord Sauna — a floating sauna moored on the lake that gives the hotel its characteristic character. This floating sauna sits directly on the water, surrounded by forest, and offers a deeply atmospheric alternative to the main hotel spa. In winter, the contrast between the heated floating cabin and the cold lake or snow-covered forest edge is striking and memorable. In summer, stepping from the sauna directly into the lake is one of the simple, perfect pleasures of Norwegian outdoor life.

Dining and Accommodation

Klækken Hotell’s restaurant serves classic Norwegian and international cuisine, and the hotel bar is a comfortable gathering point after an evening spa session. The 156 rooms cover a range of categories from standard to more spacious options, and the hotel’s event facilities make it a popular choice for conferences and group stays. For those visiting for the spa, the combination of high-quality thermal facilities and a genuine forest setting makes Klækken one of the more complete offerings within easy reach of the capital.
