Of course, even a few! Our favorite place (at Lake Krzywa Kuta) is less than 10 minutes away by car, 30 minutes by bike. It is quiet, surrounded by forest, with a pier and clean water. However, it is not guarded, if it matters to you, this type of beach is located (here and here) at lake Gołdapiwo, 10-15 km from our house.
