The estate on the southern shore of the Röblinsee Lake

A stroll around this, probably the most beautiful part of Fürstenberg /Havel is highly recommended. For example, the shoreline path, the 'Uferweg' will give you a superb view across the fully navigable Röblinsee Lake.
Cyclists on the „Berlin- Copenhagen“ long-distance cycle path will follow the Steinförder Straße direct through the estate. Walkers can also use the Röblinsee Estate as the starting point for exploring the extensive mixed woodland in the surrounding area.
The Röblinsee Estate is well prepared for tourists. Here, you can rent quaint holiday apartments, pamper yourself in a hotel and boaters can charter a houseboat for a relaxing cruise around the many lakes of the region (no licence required).
