Peaceful, invigorating, challenging and very beautiful. Very little habitation around the lake. Areas surrounding the lake are partly owned by, Lithuania, Russia, Poland.
Don't get out of your boat on Russian soil without a visa.
Restaurant will supply substantial packed lunches and beer is only 0.60EUR per bottle.
Most of the food is organic and locally grown. Hotel will cook your fish - no charge.
Location is also great for hunting in season, boar, wolves, deer, elk, fox, hare etc.
Just about totally undiscovered by foreigners and not everyone speaks English but they do try!!!
