You can go fishing either on Bobr or Kwisa- the 2 biggest rivers of the area or on lakes and ponds. All rivers and some lakes are state ownership (by PZW- Polish Angling Union) and some lakes are private. For the state rivers and lakes you have to get a daily or few- days' license (which is included in my fishing tour) and on the private ponds/ lakes you pay an entrance fee (+ caught fish fee according to its weight). Some places have BBQ facilities!
I also have 2 rods to rent if you cannot bring yours.
