The northern lakes with the Mauersee, which is 104 square kilometer big, are surrounded by dense mixed forests and fertile ground - because of that the Prussian nobility built their most beautiful mansions in this area. Lötzen (Gizycko) is the capital of water sports because of its location and size. In the end of the 19th century the swing bridge was completed and since this day it controls car and boat traffic. The bridge is an interesting attraction in this town. Near to the bridge is the waterfront; there are planted beautiful flowers and it has a free WiFi hotspot. There are also a variety of small shops.
The maritime center is the marina Steinort in the northern area next to Lötzen. The harbor is protected, very well maintained and equipped with many maritime services. Steinort (Sztynort) is a good starting point for a trip through the german history. The port area adjoins the castle of Steinort from the family von Lehndorff (Heinrich Graf von Lehndorff was executed in 1944 for his involvement in the assassination attempt on Hitler). If you have some time, leave your boat for a day and make a bike trip to Hitler's head quater in the village of Wolfsschanze, which is a good museum and memorial of the assassination.
When you reach Angersburg (Wegorzewo) you have reached the most northern point of your journey. It is worth to pass several marinas and moor in the last corner of the waterway, in front of the castle at the old town harbor. There you can also go to the open-air museum and sample Masurian country life from the last century.
