Our family tradition
Respect and sharing

As the Knaller Family, we’ve been managing the Gralhof and its forests and meadows for over 500 years. And across these centuries, a special approach has emerged and established itself. An approach rooted in respect for nature and natural resources and the belief that we are all merely nature’s guests.

If one treats nature with care, one is repaid many times over – and in ways that are unique to this region. We share these treasures with our guests. It is this that generates the very special relationship between the Gralhof, its guests and the surrounding nature. Our role is to shape this relationship and develop it further, together with our team.

The story of the Gralhof

Our story begins more than 500 years ago, when the Knaller Family settles on Lake Weissensee and establishes a farm.

1902
The first steps towards the development of tourism: the newly-built railway line connecting the east with the south makes the region easier to reach via Greifenburg-Weissensee station and attracts summer visitors.

1967
The Gralhof’s first central heating system is installed in 1967 and 1968. There is hot water and heating in every room – a real luxury for the period.
