We are halfway through March and the weather is also March. Rain and snow, frost and the occasional sunny day. Spring is still far away. Maybe time is not conducive to trips, but if someone loves nature, they will always have a nice time. The most attractive is the forest with flowing rivers. Interesting places are located in the Knyszyńska Forest, which surrounds Białystok from the north and east. Here are some photos from the trip to the Słoja river in the vicinity of Lipowy Most near Supraśl.
