The Nikolsdorfer Lauen are groundwater outflows, always flow crystal clear, are winter-warm and summer cool. We have a pure game stock of brown trout, mixed with some graylings and some rainbow trout. The shores are partly overgrown and in the open routes you should approach the water very carefully. The Lauen are a good school - you learn to throw very precisely and can watch the fish in the attack on the flies on a short leash.
